[0019] Hereinafter, embodiments of an X-ray diagnostic apparatus and an X-ray photography control method will be described with reference to the accompanying drawings. In the following embodiments, parts with the same reference mark perform the same operation, and repeated descriptions are omitted as appropriate. In addition, an X-ray diagnostic apparatus for performing examinations and treatments of the digestive tract, urinary organs, plastic surgery, IVR (Interventional Radiology), etc. will be described as an example of an X-ray diagnostic apparatus involved in the present application. In addition, the embodiments involved in the present application are not limited to these.

[0020] (Implementation Method)

[0021] use Figure 1 , an example of the X-ray diagnosis apparatus 100 according to the embodiment will be described. Figure 1 FIG. 1 is a diagram showing an example of the appearance of an X-ray diagnosis apparatus 100 according to an embodiment. Figure 1 As shown, an imaging device (also referred to as an imaging system, an imaging system or an imaging device) 110, a proximity operation table 120 having a fluoroscopic monitor 121, etc., a remote operation table 130 having an image processing device 131, a system monitor 133, a fluoroscopic monitor 135, etc., and a microphone 150 are connected to each other by any wireless or wired method. The imaging device 110 includes an X-ray tube 1a for generating X-rays, an X-ray aperture device 1b for limiting the irradiation range of X-rays, an X-ray detection unit (also referred to as an X-ray detector) 3 for detecting X-rays, and a diagnostic bed 5 on which a subject P to be irradiated with X-rays is placed. In order to make the description more specific, the following describes a case where the microphone 150 is provided in the imaging device 110.

[0022] For example, an operator such as a technician outside an examination room such as an operation room operates the remote operation table 130 to cause the imaging device 110 to perform actions such as raising and lowering the diagnostic bed 5 on which the patient (subject) is placed, or moving the imaging system such as the X-ray tube 1a and the X-ray movable aperture 1b up and down, while performing fluoroscopy or imaging. Then, the operator observes the fluoroscopic image displayed on the fluoroscopic monitor 135 of the remote operation table 130, or the imaging image or fluoroscopic image displayed on the system monitor 133. In addition, for example, an operator in the examination room operates the adjacent operation table 120 provided in the examination room, thereby performing the same processing as the above processing on the imaging device 110, and observing various images displayed on the fluoroscopic monitor 121 of the adjacent operation table 120 or the examination room monitor.

[0023] The remote operation table 130 and the adjacent operation table 120 correspond to, for example, a control console device. Figure 1As shown, the console device (remote operation table 130 and adjacent operation table 120) has input devices 137 such as various buttons and various handles related to the control of the photographic device 110, and output devices such as various monitors. The output device corresponds to, for example, the above-mentioned system monitor 133, perspective monitor 135, perspective monitor 121 and other displays. The input device 137 corresponds to various input interfaces. The input device 137 will be described later. In addition, in order to make the description specific, the console device connected to the photographic device 110 is described as the remote operation table 130.

[0024] Figure 2 1 is a diagram showing an example of the configuration of an X-ray diagnostic apparatus 100 according to the present embodiment. The X-ray diagnostic apparatus 100 includes an imaging device 110, a console device 130, and a microphone 150. The imaging device 110 includes an X-ray generator 1, a high voltage generator 2, an X-ray detector 3, a holding arm 4, a diagnostic bed 5, and a mechanism control unit 7. In addition, the imaging device 110 and the console device 130 may be collectively referred to as an X-ray diagnostic system.

[0025] The X-ray generating unit 1 generates X-rays. The X-ray generating unit 1 includes, for example, an X-ray tube 1a and an X-ray aperture device 1b. The X-ray generating unit 1 may also be referred to as an X-ray generating device. The X-ray tube 1a is a vacuum tube that generates X-rays by applying a high voltage from a high voltage generating unit 2 and supplying a filament current, and irradiating thermal electrons from a cathode (filament) toward an anode (target). X-rays are generated by the collision of thermal electrons with a target. Among the X-ray tubes 1a, for example, there are rotating anode type X-ray tubes that generate X-rays by irradiating thermal electrons to a rotating anode. In addition, the type of the X-ray tube 1a is not limited to the rotating anode type, and any type of X-ray tube can be applied.

[0026] The X-ray aperture device 1b forms an irradiation field of X-rays of the X-ray tube 1a. The X-ray aperture device 1b is arranged in front of the X-ray radiation window in the X-ray tube 1a. The X-ray aperture device 1b has a plurality of aperture blades. For example, the X-ray aperture device 1b has two aperture blades facing each other as the plurality of aperture blades. Specifically, the X-ray aperture device 1b has four aperture blades made of metal plates such as lead. Each of the four aperture blades is driven by a driving device not shown in the figure according to the region of interest input by the operator via the input interface 141 or the like. The X-ray aperture device 1b adjusts the area where the X-rays are shielded to an arbitrary size by sliding these aperture blades by the driving device. The X-ray aperture device 1b shields the X-rays outside the opening area by the adjusted aperture blades. Thus, the X-ray aperture device 1b limits the X-rays generated by the X-ray tube 1a to the region of interest that irradiates the subject P.

[0027] The high voltage generating unit 2 has a circuit such as a transformer and a rectifier, and an X-ray control device. The high voltage generating unit 2 has the function of generating a high voltage applied to the X-ray tube 1a and a filament current supplied to the X-ray tube 1a. The high voltage generating unit 2 can also be called a high voltage generating device. The X-ray control device controls the output voltage corresponding to the X-ray irradiated by the X-ray tube 1a. The high voltage generating unit 2 can be either a transformer type or an inverter type. In addition, the high voltage generating unit 2 can also be set on the holding arm 4.

[0028] The X-ray detection unit 3 detects the X-rays generated by the X-ray tube 1a. The X-ray detection unit 3 has, for example, a flat panel detector 3a corresponding to the X-ray detector, an image data generation unit 3b, and a gate driver 3c. The flat panel detector 3a is implemented, for example, by a flat panel detector (Flat Panel Detector: hereinafter referred to as FPD). The FPD has a plurality of semiconductor detection elements. The semiconductor detection element includes a direct conversion type that directly converts X-rays into electrical signals, and an indirect conversion type that converts X-rays into light using a phosphor and converts the light into electrical signals. Either method can be used in the FPD. The electrical signal generated by the FPD is output to the image data generation unit 3b.

[0029] The image data generating unit 3b is composed of a charge / voltage converter 3b-1, an A / D (Analog to Digital) converter 3b-2, and a parallel / serial converter 3b-3. The charge / voltage converter 3b-1 converts the electrical signal output from the flat panel detector 3a into a voltage signal, and outputs it to the A / D converter 3b-2. Under the control of the system control unit 11, the A / D converter 3b-2 converts the electrical signal converted into a voltage signal into X-ray image data as digital data, and outputs it to the parallel / serial converter 3b-3. Under the control of the system control unit 11, the parallel / serial converter 3b-3 converts the X-ray image data after the A / D conversion from parallel data to serial data, and outputs it to the image storage circuit 9. The image data generating unit 3b can also be called an image data generating device.

[0030] The gate driver 3 c drives the detection elements of the flat panel detector 3 a under the control of the system control unit 11 .

[0031] The holding arm 4 holds the X-ray tube 1a that generates X-rays and the flat panel detector 3a that is opposite to the X-ray tube 1a and detects X-rays so that they can move. In other words, the X-ray tube 1a and the flat panel detector 3a are opposite to each other and are mounted on the end of the holding arm 4. The holding arm 4 supports the X-ray aperture device 1b and the flat panel detector 3a so that they can rotate freely, with the straight line connecting the focus of the X-ray generated in the X-ray tube 1a and the center of the flat panel detector 3a as the rotation axis. The holding arm 4 rotates the X-ray aperture device 1b and the flat panel detector 3a around the rotation axis by the operation of the holding arm moving mechanism. In addition, the holding arm 4 can also hold the X-ray generating unit 1 and the X-ray detecting unit 3 in a manner that can change the source image receiving surface distance (Source Image Distance: hereinafter referred to as SID), for example.

[0032] The diagnostic bed 5 has a top plate and a base. The subject P is placed on the top plate. The base supports the top plate so that it can move parallel to the long axis direction, the short axis direction and the vertical direction of the top plate, for example. In addition, the base supports the top plate so that it can rotate with the short axis direction, the long axis direction and the vertical direction of the top plate as the rotation axis.

[0033] The mechanism unit (not shown) (may also be referred to as a mechanism device) has a holding arm moving mechanism and a diagnostic bed moving mechanism. The holding arm moving mechanism and the diagnostic bed moving mechanism are implemented by, for example, a motor or an actuator. Under the control of the mechanism control unit 7, the holding arm moving mechanism moves the holding arm 4 to a position indicated by the operator or preset. Under the control of the mechanism control unit 7, the diagnostic bed moving mechanism moves the top plate in the diagnostic bed 5 to a position indicated by the operator or preset.

[0034] The mechanism control unit 7 controls the mechanism unit under the control of the system control unit 11. For example, the mechanism control unit 7 controls the movement of the holding arm moving mechanism and the movement of the diagnostic bed moving mechanism based on the input operation received from the operator via the input interface 141. Specifically, the mechanism control unit 7 reads out the mechanism control program stored in the storage device and expands it on the memory in the processor in the mechanism control unit 7, and controls the movement of the holding arm moving mechanism and the movement of the diagnostic bed moving mechanism according to the expanded mechanism control program. The mechanism control unit 7 can also be called a processing circuit (mechanism control circuit) that controls the mechanism device.

[0035] The microphone 150 collects the user's voice. The user is, for example, a doctor who performs various treatments on the subject P. The microphone 150 is implemented by a microphone (microphone) composed of electronic components that convert sound into electrical signals. The microphone 150 outputs the collected voice to the remote operation table 130. Figure 1 and Figure 2As shown in the figure, the microphone 150 is mounted on the imaging device 110, but the position of the microphone 150 is not limited thereto. That is, the microphone 150 may be installed on the ceiling and / or wall of the examination room or near the operation table 120 as long as it can collect the user's voice.

[0036] The image processing device 131 includes an image storage circuit 9, a system control unit 11, a memory 143, and a processing circuit 145. The image storage circuit 9 is composed of a hard disk drive (HDD), a semiconductor memory, etc. The image storage circuit 9 stores the X-ray image data output from the image data generator 3b.

[0037] The system control unit 11 controls the X-ray generator 1, the high voltage generator 2, the gate driver 3c, the A / D converter 3b-2, the parallel / serial converter 3b-3, the mechanism control unit 7, the image storage circuit 9, the display unit 10, etc. based on the input operation etc. received from the operator via the input interface 141. Specifically, the system control unit 11 reads out the system control program and expands it on its own memory, and controls each part of the X-ray diagnosis apparatus 100 according to the expanded control program. For example, the system control unit 11 performs a magnification process or an image operation process etc. on the X-ray image data stored in the image storage circuit 9, and generates an X-ray image to be displayed.

[0038] In addition, the system control unit 11 outputs the X-ray image stored in the image storage circuit 9 to the display image memory 10a of the display unit 10 in response to the operator's instruction for image display, etc. In addition, the system control unit 11 outputs the electric signal corresponding to the voice output from the microphone 150 to the processing circuit 145. In addition, the electric signal corresponding to the voice may be directly output to the processing circuit 145 without passing through the system control unit 11. The system control unit 11 is implemented, for example, by a processing circuit (which may also be referred to as a system control circuit) that controls various parts of the X-ray diagnosis device 100. In addition, the system control unit 11 may also be simply referred to as a control unit.

[0039] Specifically, the system control unit 11 sets a region of interest (ROI) for the X-ray image through the setting function 111 according to the instruction of the operator through the input interface 141. The system control unit (system control circuit) 11 for realizing the setting function 111 corresponds to the setting unit. In addition, the system control unit 11 performs image processing on the entire region or ROI of the X-ray image through the image processing function 113 according to the instruction of the operator through the input interface 141. For example, a program (image processing program) for executing the image processing is stored in the memory 143. At this time, the image processing function 113 reads the image processing program from the memory 143, expands it on the memory in the system control unit 11, and executes it, thereby executing the image processing. The system control unit (system control circuit) 11 for realizing the image processing function 113 corresponds to the image processing unit. This image processing can use known processing, so the description is omitted. In addition, various image processing is not limited to being executed by the system control unit 11, and can also be implemented by an image processing circuit or processing circuit 145 that is not shown and is separately provided.

[0040] The display unit 10 includes a display image memory 10a, a D / A (Digital to Analog) converter 10b, a display control unit 10c, and a monitor 10d. The display image memory 10a stores image data output from the image storage circuit 9 and outputs it to the D / A converter 10b. The D / A converter 10b converts the image data output from the display image memory 10a into an analog signal and outputs it to the display circuit 10c. The display circuit 10c displays an X-ray image based on the image data output from the D / A converter 10b on the monitor 10d.

[0041] In addition, the display unit 10 can be implemented as a display and / or various monitors. That is, the display unit 10 corresponds to, for example, Figure 1 The perspective monitor 121, the system monitor 133, the perspective monitor 135, etc. in the display. At this time, as a display, for example, a liquid crystal display (LCD: Liquid Crystal Display), a CRT (Cathode Ray Tube) display, an organic EL display (OELD: Organic ElectroLuminescence Display), a plasma display or any other display can be appropriately used. In addition, the display can be either a desktop type or a tablet terminal that can communicate wirelessly with the system control unit 11 and the image storage circuit 9. In addition, when the monitor 10d displays the X-ray image as digital data, the D / A converter 10b is not required.

[0042] The input interface 141 receives various input operations from the operator, converts the received input operations into electrical signals, and outputs them to the system control unit 11. The input interface 141 receives operations for moving at least one of the holding arm 4 and the diagnostic bed 5, X-ray conditions related to the generation of X-rays, conditions related to image processing, operations of the four aperture blades, etc. from the operator. As the input interface 141, for example, a mouse, a keyboard, a trackball, a switch, a button, a joystick, a foot switch, a touch pad, a touch panel display, etc. can be appropriately used. The input interface 141 corresponds to Figure 1 The input device 137 in.

[0043] In addition, in the present embodiment, the input interface 141 is not limited to physical operation components such as a mouse, a keyboard, a trackball, a switch, a button, a joystick, a touchpad, and a touch panel display. For example, a processing circuit for receiving an electric signal corresponding to an input operation from an external input device provided separately from the device and outputting the electric signal to the system control unit 11 is also included in the example of the input interface 141. In addition, the input interface 141 may also be composed of a tablet terminal or the like that can communicate wirelessly with the system control unit 11.

[0044] The memory 143 stores a program (speech recognition program) related to the implementation of the speech recognition function 151. The memory 143 stores a program (calculation program) related to the implementation of the movement amount calculation function 153. The speech recognition program is a program that recognizes the speech uttered (spoken) by the user using an electrical signal corresponding to the user's speech output from the microphone 150. For example, the speech recognition program recognizes a numerical value corresponding to the speech based on the user's speech collected by the microphone 150. As the speech recognition program, a known application related to speech recognition can be used, so the description is omitted.

[0045] The calculation program is a program for calculating the movement amount of at least one device among the multiple devices in the camera system based on the recognized numerical value and the current positions of the multiple devices in the camera system. The processing content of the calculation program will be described later in the movement amount calculation function 153. The processing achieved by implementing the voice recognition program and the calculation program is a processing related to the control of the movement of various devices in the camera system, and can also be called voice movement control processing. The voice movement control processing will be described later.

[0046] The memory 143 stores position information of various components in the imaging device 110 when performing X-ray imaging on the subject P. The position information of various components is, for example, the position of a plurality of aperture blades in the X-ray aperture device 1b, the position of the diagnostic bed 5 relative to the X-ray tube 1a, etc. In accordance with the X-ray imaging, for example, the position information is updated each time a fluoroscopic image is generated.

[0047] The memory 143 is implemented by a storage device such as a HDD, SSD (Solid State Drive) or an integrated circuit storage device that stores various information. The memory 41 may be implemented by a drive device that reads and writes various information with a removable storage medium such as a CD (Compact Disc), a DVD (Digital Versatile Disc), a flash memory, or a semiconductor memory element such as a RAM (Random Access Memory) in addition to a HDD or SSD.

[0048] The processing circuit 145 calculates the movement amount related to the voice movement control processing for the photographing device 110 by executing the voice recognition function 151 and the movement amount calculation function 153. If an electrical signal corresponding to the voice is received from the microphone 150, the processing circuit 145 performs the voice recognition processing on the electrical signal through the voice recognition function 151, and generates the result of the voice recognition processing (hereinafter referred to as the recognition result). The processing circuit 145 for implementing the voice recognition function 151 corresponds to the voice recognition unit. In addition, the processing circuit 145 for implementing the movement amount calculation function 153 corresponds to the movement amount calculation unit.

[0049] In order to make the description more specific, the control object of the voice movement control process is set to at least one aperture blade in the X-ray aperture device 1b. At this time, the user says, for example, "aperture voice operation". "Aperture voice operation" corresponds to the start word for starting the voice movement control process. In addition, the start word of the voice movement control process is not limited to the above-mentioned "aperture voice operation", and any voice, such as "voice operation, aperture", which has the intention of operating the aperture by voice, can be used, or other voices. In addition, other voices can also be words related to the words used by the doctor to instruct the technician to operate the aperture. The microphone 150 collects the voice and outputs an electrical signal corresponding to the collected voice to the remote control table 130. The voice recognition function 151 recognizes that the control object of the voice movement control process is the aperture based on the user's voice. The voice recognition function 151 outputs the recognition result indicating that the control object is the aperture (hereinafter referred to as the aperture control instruction) to the system control unit 11.

[0050] In addition, the control object of the voice movement control process is not limited to the aperture blades. For example, when the control object of the voice movement control process is the diagnostic bed 5, the activation word is "diagnostic bed voice operation" etc. The case where the control object of the voice movement control process is other than the aperture blade will be described later in the modification examples.

[0051] In response to the reception of the aperture control instruction, the system control unit 11 causes the display unit (display) 10 to display multiple numerical values ​​indicating the positions in the X-ray image generated by the X-ray photography of the subject P by the photography device 110 together with the X-ray image. That is, the display unit 10 displays the multiple numerical values ​​indicating the positions together with the X-ray image in response to the reception of the aperture control instruction. At this time, the display unit 10 may also display multiple scales corresponding to the multiple numerical values.

[0052] After saying "aperture voice operation", the user says the configuration of the aperture blades to be moved, and the numerical value of the coordinates of the aperture blades at the destination of movement. The configuration of the aperture blades to be moved is the configuration of the aperture blades corresponding to the top, bottom, left, and right in the X-ray image displayed on the display unit 10. In addition, the numerical value of the coordinates of the aperture blades at the destination of movement corresponds to the numerical value (coordinate value) displayed on the display unit 10. For example, the coordinates of the destination of movement correspond to the position in the coordinate system set for the X-ray image displayed on the display unit 10. The origin of the coordinate system is set to, for example, the upper left end of the displayed X-ray image. In addition, the origin of the coordinate system can be set arbitrarily. The coordinate system is stored in the memory 143 in correspondence with the position information of various components in the imaging device 110. That is, the correspondence between the position information and the coordinate system is stored in the memory 143 in association, for example, as a correspondence table (hereinafter referred to as a position coordinate correspondence table).

[0053] For example, when the diaphragm blade on the left side relative to the X-ray image is to be moved to a position with a numerical value of 15, the voice spoken about the arrangement of the diaphragm blade to be moved and the numerical value of the coordinate of the diaphragm blade to be moved is, for example, "diaphragm left, 15" or the like. This voice means that the diaphragm blade on the left side relative to the X-ray image is to be moved to the coordinate indicating "15" displayed together with the X-ray image. In addition, the voice spoken about the arrangement of the diaphragm blade to be moved and the numerical value of the coordinate of the diaphragm blade to be moved is not limited to the above-mentioned "diaphragm left, 15" or the like, and may be other voices such as "15, diaphragm left" or the like.

[0054] The microphone 150 collects the user's voice (hereinafter referred to as a movement instruction word) related to the configuration of the aperture blade to be moved and the numerical value of the coordinates of the aperture blade indicating the movement destination, and outputs an electric signal corresponding to the collected movement instruction word to the remote control desk 130. The voice recognition function 151 recognizes, for example, one of two opposing aperture blades based on the user's voice, that is, the movement instruction word. Specifically, the voice recognition function 151 recognizes the configuration of the aperture blade to be controlled by the voice movement control process and the numerical value of the coordinates of the aperture blade indicating the movement destination based on the user's movement instruction word. The voice recognition function 151 outputs the recognition result (hereinafter referred to as the aperture movement instruction) indicating the information for determining the aperture blade to be moved and the coordinates of the movement destination to the movement amount calculation function 153.

[0055] The processing circuit 145 calculates the movement amount of the moving object based on the aperture movement instruction through the movement amount calculation function 153. For example, the movement amount calculation function 153 obtains the current position information and the position coordinate correspondence table of the aperture blade of the moving object from the memory 143, and calculates the movement amount of the moving object using the current position information, the position coordinate correspondence table, and the coordinates of the moving destination. The movement amount calculation function 153 outputs the calculated movement amount to the system control unit 11. At this time, the system control unit 11 moves the moving object (for example, the aperture blade) according to the calculated movement amount.

[0056] That is, the system control unit 11 controls the imaging device 110 according to the position (coordinates of the moving object of the moving destination) corresponding to the recognized numerical value among the plurality of numerical values ​​displayed on the display unit 10 together with the X-ray image. For example, the system control unit 11 controls the X-ray aperture device 1b so as to move at least one aperture blade among the plurality of aperture blades to the position corresponding to the recognized numerical value. Specifically, the system control unit 11 controls the X-ray aperture device 1b so as to move one aperture blade among the two opposing aperture blades to the position corresponding to the recognized numerical value.

[0057] The processing circuits for implementing the above-mentioned mechanism control unit 7, system control unit 11, etc., and the processing circuit 145 have processors such as CPU (Central Processing Unit), MPU (Micro Processing Unit) or GPU (Graphics Processing Unit), and memories such as ROM (Read Only Memory) or RAM (Random Access Memory) as hardware resources. In addition, the processing circuit can also be implemented by processors such as Application Specific Integrated Circuit (ASIC), Field Programmable Gate Array (FPGA), or other Complex Programmable Logic Device (CPLD), Simple Programmable Logic Device (SPLD) and the like.

[0058] The various functions executed in the processor are stored in a memory (not shown) in the form of a program that can be executed by a computer. The processor is a processor that realizes the functions corresponding to each program by reading out and executing the program from the memory. In other words, each circuit that has read out the state of each program has a function corresponding to the read program.

[0059] The above is an explanation of the overall structure of the X-ray diagnosis apparatus 100 according to the embodiment. Based on this structure, the X-ray diagnosis apparatus 100 according to the embodiment displays the numerical value and scale of the coordinate system together with the X-ray image in response to the user speaking the start word, and performs the voice movement control process for moving the imaging system in response to the user speaking the voice related to the aperture movement instruction. Figures 3 to 7 Describe the process of voice mobile control processing.

[0060] Figure 3 2 is a flowchart showing an example of the procedure of the sound movement control process. As described above, in the sound movement control process in the present embodiment, the aperture blade is described as an example of a control object. Figure 4 This is a diagram showing an example of an overview of the process of voice movement control processing.

[0061] (Voice Mobile Control Processing)

[0062] (Step S301)

[0063] The imaging device 110 generates an X-ray image XI by radiating X-rays to the subject P. Position information of the aperture blades when radiating X-rays is stored in the memory 143 as current position information of the aperture blades. The display unit 10 displays the X-ray image XI.

[0064] (Step S302)

[0065] If the user UR says the start word SUW such as "iris voice operation" (step S302: Yes), the microphone 150 collects the voice corresponding to the start word SUW. The microphone 150 converts the collected voice into an electrical signal and outputs it to the remote operation desk 130. Next, the process of step S303 is executed. If the user UR does not say the start word SUW (step S302: No), the process of step S310 is executed.

[0066] (Step S303)

[0067] The processing circuit 145 recognizes the start word SUW through the voice recognition function 151. Thus, the voice recognition function 151 determines the control object in the voice movement control process. In response to the recognition of the start word SUW, the system control unit 11 causes a plurality of numerical values ​​NV representing positions in the X-ray image XI to be displayed on the display unit 10 together with the X-ray image XI. That is, after the start word SUW is spoken, the display unit 10 causes a plurality of numerical values ​​NV representing positions in the X-ray image XI generated by X-ray photography of the subject P by the imaging system 110 (coordinates representing positions to which the aperture blades can move) to be displayed together with the X-ray image XI. At this time, the display unit 10 may also display a plurality of scales SC corresponding to the plurality of numerical values ​​NV, respectively. Figure 4 In the example shown, in response to the utterance of the start word SUW, a numerical value NV and a scale SC are displayed in the vertical and horizontal directions of the X-ray image XI.

[0068] The display of the numerical value NV and scale SC corresponding to the activation word is not limited to Figure 4 For example, Figure 5 As shown, the display unit 10 may display the numerical value CP indicating the current position of the aperture blade and the scale corresponding to the numerical value CP together with the X-ray image XI, the numerical value NV, and the scale SC. Figure 5 The shadow SR in FIG. 1 corresponds to the area where the X-ray aperture is used to shield the X-rays (shielded area). Figure 6 As shown in FIG. 1 , the display unit 10 may also display a scale line (guideline) GL corresponding to the scale together with the X-ray image XI, the numerical value NV and the scale SC. Figure 7 As shown, the display unit 10 may display the numerical value NV and the scale SC corresponding to the activation word outside the X-ray image XI (image area).

[0069] (Step S304)

[0070] If the voice (movement indicator) MIW of the user UR is collected about the numerical value NV displayed on the display unit 10 (step S304: Yes), the process of step S305 is executed. If the voice (movement indicator) MIW of the user UR is not collected about the numerical value NV displayed on the display unit 10 (step S304: No), the process of step S308 is executed. In addition, the collected numerical value is not limited to the numerical value NV displayed on the display unit 10, and may be a value between the numerical values ​​NV displayed on the display unit 10.

[0071] (Step S305)

[0072] The processing circuit 145 recognizes the numerical value corresponding to the voice based on the voice of the user UR collected by the microphone 150 regarding the numerical value through the voice recognition function 151. Specifically, the voice recognition function 151 generates an aperture movement instruction, which is a recognition result of the aperture blades of the moving object and the coordinates of the moving destination, by performing voice recognition processing on the electrical signal corresponding to the voice of the user UR.

[0073] like Figure 4 As shown, the user said "aperture left 15" as voice. Therefore, the content of the aperture movement instruction is to move the aperture blade on the left side relative to the X-ray image XI to the position of the scale 15. That is, the coordinates of the movement destination of the left aperture blade are 15. In addition, when the collected numerical value is a value between the numerical value NV displayed on the display unit 10, that is, a numerical value that does not correspond to multiple scales SC, the voice recognition function 151 can also recognize the numerical value that does not correspond to the multiple scales displayed on the display unit 10 based on the user's voice collected by the microphone 150. That is, in Figure 4 In the display example shown, the numerical value NV indicates 10, 20, and 30, but the voice recognition function 151 can also recognize numerical values ​​between these numbers. The voice recognition function 151 outputs the aperture movement instruction to the movement amount calculation function 153.

[0074] (Step S306)

[0075] The processing circuit 145 calculates the movement amount of the moving object based on the aperture movement instruction including the recognized numerical value through the movement amount calculation function 153. For example, the movement amount calculation function 153 reads the current position information and the position coordinate correspondence table of the aperture blade of the moving object from the memory 143. Figure 4In the example of , the movement amount calculation function 153 uses the current position information of the left aperture blade, the position coordinate correspondence table, and the coordinates (15) of the movement destination to calculate the movement amount of the left aperture blade. That is, the movement amount calculation function 153 calculates the movement amount of the aperture blade to be moved based on the aperture movement instruction, the current position information of the aperture blade to be moved, and the position coordinate correspondence table. The movement amount calculation function 153 outputs the movement amount of the aperture blade to be moved to the system control unit 11.

[0076] (Step S307)

[0077] The system control unit 11 controls the imaging device 110 according to the calculated movement amount of the moving object. Figure 4 In the example shown, the system control unit 11 controls the X-ray aperture device 1b so that the left aperture blade moves to a position where the numerical value of the scale in the X-ray image XI is 15. Figure 4 In the example shown, the area of ​​the moved aperture blades in the X-ray image XI is indicated by hatching. Figure 4 The shadow SR in corresponds to the region where the X-ray diaphragm shields the X-rays (shielded region). Thus, when the user speaks a numerical value, the diaphragm blades are arranged at positions corresponding to the designated numerical value on the monitor 10d.

[0078] (Step S308)

[0079] The system control unit 11 determines whether a predetermined time has passed since the plurality of numerical values ​​NV were displayed on the display unit 10. In addition, the system control unit 11 determines whether a predetermined time has passed after controlling the imaging device 110. The predetermined time can be arbitrarily set, for example, from several seconds to more than ten seconds, and is preset and stored in the memory 143. When the predetermined time has passed since the plurality of numerical values ​​NV were displayed on the display unit 10 (step S308: Yes), the process of step S309 is executed. When the predetermined time has not passed since the plurality of numerical values ​​NV were displayed on the display unit 10 (step S308: No), the process after step S304 is repeated.

[0080] (Step S309)

[0081] The system control unit 11 makes the multiple scales SC and the multiple numerical values ​​NV displayed together with the X-ray image XI not displayed. That is, the display unit 10 displays only the X-ray image XI under the control of the system control unit 11. After this step, the processing after step S301 is repeated. Specifically, when a specified time has passed since the multiple numerical values ​​were displayed on the display unit 10, or when the movement of the moving object is completed, the system control unit 11 makes the multiple numerical values ​​NV and the scales SC on the display unit 10 not displayed. That is, if a predetermined time has passed while the scales SC and the numerical values ​​NV are displayed on the image, the scales SC and the numerical values ​​NV on the image are no longer displayed. For example, in Figure 4 In the example shown, when the left aperture blade moves to the position where the scale SC in the X-ray image XI is 15 and a predetermined time has passed, the system control unit 11 controls the display unit 10 so that the scale SC and the numerical value NV in the X-ray image XI are not displayed.

[0082] (Step S310)

[0083] If the X-ray imaging of the subject P is completed (step S310: Yes), the voice movement control process is completed. If the X-ray imaging of the subject P is not completed (step S310: No), the process after step S301 is repeated. For example, the end of the X-ray imaging is input by the user through the input interface 141.

[0084] The X-ray diagnostic device 100 involved in the embodiment described above will display multiple numerical values ​​NV representing the positions in the X-ray image XI generated by X-ray photography of the subject P by the imaging system 110 having an X-ray tube 1a, an X-ray aperture 1b, an X-ray detection unit 3 and a diagnostic bed 5 together with the X-ray image XI, recognize the numerical value corresponding to the voice based on the voice of the user UR collected about the numerical value, and control the imaging system 110 according to the position (movement amount) corresponding to the recognized numerical value among the multiple numerical values ​​NV.

[0085] For example, the X-ray aperture device 1b in the X-ray diagnosis apparatus 100 according to the embodiment includes a plurality of aperture blades, and the X-ray diagnosis apparatus 100 according to the embodiment controls the X-ray aperture device 1b so that at least one of the plurality of aperture blades is asymmetrically moved to a position corresponding to the recognized numerical value. Specifically, the X-ray aperture device 1b in the X-ray diagnosis apparatus 100 according to the embodiment includes two aperture blades facing each other as the plurality of aperture blades, and the X-ray diagnosis apparatus 100 according to the embodiment recognizes one of the two aperture blades based on the voice of the user UR, and controls the X-ray aperture device 1b so that the one aperture blade is moved to a position corresponding to the recognized numerical value.

[0086] Thus, according to the X-ray diagnosis apparatus 100 involved in the embodiment, a moving object such as an aperture blade can be smoothly operated to a position intended by a user UR such as a physician who performs treatment on the subject P. Therefore, according to the X-ray diagnosis apparatus 100 involved in the embodiment, the irradiation range can be limited as much as possible to the minimum region of interest required by the user UR such as the physician, and thus the radiation to the subject P can be reduced.

[0087] In addition, the X-ray aperture device 1b in the X-ray diagnosis device 100 according to the embodiment has two aperture blades facing each other as a plurality of aperture blades, and the X-ray diagnosis device 100 according to the embodiment further displays a plurality of scales SC corresponding to the plurality of numerical values ​​NV, and the numerical value and scale corresponding to the current position CP of the aperture blade. Therefore, according to the X-ray diagnosis device 100 according to the embodiment, the user UR can grasp the numerical value corresponding to the current position of the aperture blade at a glance, and can easily say the position of the moving destination. Moreover, according to the X-ray diagnosis device 100 according to the embodiment, by displaying a plurality of numerical values ​​NV and a plurality of scales SC, it is easy to change and control the position of the moving destination, and the moving object can be accurately moved to the position desired by the user UR. Therefore, according to the X-ray diagnosis device 100 according to the embodiment, by displaying a plurality of numerical values ​​NV and a plurality of scales SC, the operability of the movement of the moving object based on voice is improved, and the number of adjustments to the movement of the moving object can be further reduced, thereby improving the throughput of the examination of the subject P,

[0088] In addition, the X-ray diagnosis apparatus 100 according to the embodiment does not display the plurality of numerical values ​​NV on the display unit 10 when a predetermined time has passed since the plurality of numerical values ​​NV were displayed on the display unit 10. Thus, according to the X-ray diagnosis apparatus 100 according to the embodiment, by displaying the scale SC and the numerical value NV on the display unit 10 only during voice operation, it is possible to prevent the scale SC and the numerical value NV from obstructing the user UR from observing the X-ray image XI. Therefore, according to the X-ray diagnosis apparatus 100 according to the embodiment, it is possible to improve the efficiency of the user UR in observing the X-ray image XI.

[0089] In addition, the X-ray diagnosis apparatus 100 according to the embodiment further displays a plurality of scales SC corresponding to the plurality of numerical values ​​NV, and recognizes numerical values ​​that do not correspond to the scales SC based on the voice of the user UR. Thus, according to the X-ray diagnosis apparatus 100 according to the embodiment, it is also possible to specify numerical values ​​that are not displayed on the scales.

[0090] In addition, the X-ray diagnosis apparatus 100 according to the embodiment further displays a plurality of scale marks SC corresponding to the plurality of numerical values ​​NV, and a plurality of scale lines GL corresponding to the plurality of scale marks SC. Thus, according to the X-ray diagnosis apparatus 100 according to the embodiment, the numerical value corresponding to the position of the moving destination of the moving object can be grasped at a glance, and the convenience of the user UR in saying the numerical value can be improved.

[0091] In addition, the X-ray diagnosis apparatus 100 according to the embodiment displays a plurality of numerical values ​​NV outside the X-ray image XI. Thus, according to the X-ray diagnosis apparatus 100 according to the embodiment, a plurality of numerical values ​​NV are displayed outside the X-ray image XI, so that the scale SC and the numerical values ​​NV can be prevented from hindering the user UR from observing the X-ray image XI. Therefore, according to the X-ray diagnosis apparatus 100 according to the embodiment, the efficiency of the user UR observing the X-ray image XI can be improved.

[0092] Thus, according to the X-ray diagnosis apparatus 100 according to the embodiment, even if both hands of the doctor who is the user UR are occupied, the imaging device 110 can be smoothly operated to the position intended by the doctor.

[0093] (First Modification)

[0094] In this modification, two opposing aperture blades are moved symmetrically by voice operation. That is, the control object of the voice movement control process in this modification is the two opposing aperture blades in the X-ray aperture device 1b. Figure 8 This is a diagram showing an example of an overview of the process of the voice movement control processing involved in this variation.

[0095] In this modification, after saying "aperture voice operation", the user UR says the configuration of the aperture blades to be moved and the numerical value indicating the coordinates of the aperture blades at the destination of movement. The configuration of the aperture blades to be moved is a configuration of a group of aperture blades corresponding to the top and bottom or the left and right in the X-ray image XI displayed on the display unit 10. In addition, the numerical value indicating the coordinates of the aperture blades at the destination of movement corresponds to the numerical value (coordinate value) displayed on the display unit 10 as in the embodiment.

[0096] For example, when the left diaphragm blade of a pair of left and right diaphragm blades with respect to the X-ray image XI is to be moved to a numerical value (10), and the right diaphragm blade is to be moved to a numerical value 30, the voice spoken about the arrangement of the diaphragm blades to be moved and the numerical value indicating the coordinates of the diaphragm blades to be moved is, for example, "diaphragm left and right, 10" or the like. This voice means that the diaphragm blade on the left side with respect to the X-ray image XI is to be moved to the coordinate indicating "10" displayed together with the X-ray image XI, and the diaphragm blade on the right side with respect to the X-ray image XI is to be moved to the coordinate indicating "30" displayed together with the X-ray image XI. In addition, the voice spoken about the arrangement of the diaphragm blades to be moved and the numerical value indicating the coordinates of the diaphragm blades to be moved is not limited to the above-mentioned "diaphragm left and right, 10" or the like, and may be, for example, other voices such as "10, diaphragm left and right".

[0097] The microphone 150 collects the movement instruction word MIW and outputs an electrical signal corresponding to the collected movement instruction word MIW to the remote operation table 130. The voice recognition function 151 recognizes the two aperture blades based on the voice of the user UR, that is, the movement instruction word MIW. Specifically, the voice recognition function 151 recognizes the configuration of the aperture blades to be controlled by the voice movement control process and the numerical value indicating the coordinates of the aperture blades of the movement destination based on the movement instruction word MIW of the user UR. The voice recognition function 151 outputs the aperture movement instruction to the movement amount calculation function 153.

[0098] The processing circuit 145 calculates the movement amount of the moving object based on the aperture movement instruction through the movement amount calculation function 153. The movement amount calculation function 153 calculates the movement amount in the same way as in the embodiment, so the description is omitted. At this time, the system control unit 11 moves the moving object (for example, two opposing aperture blades) according to the calculated movement amount. That is, the system control unit 11 Figure 8 As shown, the X-ray aperture device 1b is controlled so that the two aperture blades are symmetrically moved to positions corresponding to the recognized numerical values. Figure 8 The shadow SR in the figure corresponds to the area where the X-rays are shielded by the X-ray aperture (shielded area). Figure 3 Except that the voice and control object of user UR in step S304 are different from those in the implementation mode, everything is the same as the implementation mode, so the description of the voice movement control processing is omitted.

[0099] The X-ray aperture device 1b in the X-ray diagnosis device 100 according to the present modification has two aperture blades facing each other as a plurality of aperture blades, and the X-ray diagnosis device 100 according to the present modification recognizes the two aperture blades based on the voice of the user UR, and controls the X-ray aperture device 1b in such a manner that the two aperture blades are symmetrically moved to positions corresponding to the recognized values. Thus, according to the X-ray diagnosis device 100 according to the first modification, the two aperture blades facing each other can be moved simply and symmetrically according to the voice of the user UR, and the operability of the aperture operation can be improved. Other effects are the same as those of the embodiment, and therefore description thereof is omitted.

[0100] (Second Modification)

[0101] In this modification, the plurality of aperture blades are operated independently to move the center position of the X-ray irradiation range by voice operation. That is, in this modification, the movement of the plurality of aperture blades is controlled asymmetrically in order to move the center position in the X-ray image XI. In other words, in this modification, the plurality of aperture blades are moved independently in order to move the center position in the X-ray image XI. Fig. 9 This is a diagram showing an example of an overview of the process of the voice movement control processing involved in this variation.

[0102] In this modification, after saying "aperture voice operation", the user UR says the coordinates of the center position of the moving destination in the X-ray image XI (for example, in the order of x coordinate, y coordinate). Fig. 9 As shown in the figure, when the position coordinates (30, 30) in the X-ray image XI before the center position movement action is set as the center position in the next X-ray photography, the voice spoken to indicate the coordinates of the center position is, for example, "center movement, 30, 30" etc. In addition, the voice spoken to indicate the coordinates of the center position is not limited to the above-mentioned "center movement, 30, 30" etc., and may be other voices such as "30, 30, center movement" etc.

[0103] The microphone 150 collects the movement instruction word MIW and outputs an electrical signal corresponding to the collected movement instruction word MIW to the remote operation table 130. The voice recognition function 151 recognizes the numerical value indicating the center position of the X-ray irradiation range based on the voice of the user UR, that is, the movement instruction word MIW. The voice recognition function 151 outputs the coordinates indicating the center position to the movement amount calculation function 153 as an aperture movement instruction.

[0104] The processing circuit 145 calculates the movement amount of each of the plurality of aperture blades based on the aperture movement instruction through the movement amount calculation function 153. The movement amount calculation function 153 calculates the movement amount in the same manner as in the embodiment, so the description thereof is omitted. At this time, the system control unit 11 moves the plurality of aperture blades to be moved according to the calculated movement amount. That is, the system control unit 11 Fig. 9 As shown, the X-ray aperture device 1b is controlled so that the plurality of aperture blades are independently (asymmetrically) moved so that the position corresponding to the recognized numerical value (the coordinates of the center position) becomes the center position of the irradiation range.

[0105] like Fig. 9 As shown, in this variant, the field of view size is not changed, but the field of view position is moved. In other words, the voice movement control processing in this variant corresponds to: according to the voice (coordinates) of the user UR, while maintaining the field of view size, the center position in the X-ray image XI is changed, that is, the X-ray irradiation range is moved parallel. Figure 3 Except that the voice and control object of user UR in step S304 are different from those in the implementation mode, everything is the same as the implementation mode, so the description of the voice movement control processing is omitted.

[0106] The X-ray diagnostic apparatus 100 according to this modification recognizes the numerical value indicating the center position of the X-ray irradiation range based on the voice of the user UR, and controls the X-ray aperture device 1b in such a manner that the plurality of aperture blades are independently moved so that the position corresponding to the recognized numerical value becomes the center position of the irradiation range. Thus, according to the X-ray diagnostic apparatus 100 according to the second modification, the plurality of aperture blades can be moved asymmetrically in accordance with the voice of the user UR, so as to change the center position in the X-ray image XI while maintaining the size of the field of view. That is, according to the X-ray diagnostic apparatus 100 according to the second modification, by inputting coordinates by voice, the plurality of aperture blades can be operated in such a manner that the position of the coordinates becomes the center of the image. In other words, according to the X-ray diagnostic apparatus 100 according to the second modification, the field of view position can be operated without changing the size of the field of view. Other effects are the same as those of the embodiment and the first modification, and therefore description thereof is omitted.

[0107] (Third Modification)

[0108] In this modification, instead of an absolute value, a relative value is used with the position of the current control object (e.g., aperture blade) as 0 as the specification of the numerical value by voice. That is, in this modification, the voice spoken by the user UR is different from the embodiment and becomes a word indicating a relative value. A positive (+) or negative (-) is added to the relative value. For example, a positive value indicates the right direction relative to the X-ray image XI. A negative value indicates the left direction relative to the X-ray image XI. Therefore, the relative value is equivalent to the movement amount of the aperture on the X-ray image XI. Fig.10 This is a diagram showing an example of an overview of the process of the voice movement control processing involved in this variation.

[0109] In this modification, after saying "aperture voice operation", the user UR says the configuration of the aperture blades to be moved and the numerical value (relative value) indicating the relative position of the aperture blades at the destination of movement. The configuration of the aperture blades to be moved is the configuration of the aperture blades corresponding to the top, bottom, left, and right in the X-ray image displayed on the display unit 10. In addition, the numerical value indicating the relative position of the aperture blades at the destination of movement is a relative value relative to the numerical value (coordinate value) displayed on the display unit 10. Therefore, the coordinates of the destination of movement correspond to the value obtained by adding or subtracting the relative value to the position of the current control object (e.g., aperture blade).

[0110] For example, when the left aperture blade of a pair of aperture blades on the left and right sides of the X-ray image XI is relatively moved to the right by 5, the voice about the arrangement and relative value of the aperture blade to be moved is, for example, Fig.10 As shown in the figure, it is "aperture left, +5" etc. Fig.10 As shown in the figure, when the coordinate of the current position of the left aperture blade is 10, the spoken voice means to move the aperture blade on the left side relative to the X-ray image XI to the coordinate indicating "10+5" displayed together with the X-ray image XI. In addition, the voice spoken about the arrangement of the aperture blade to be moved and the numerical value indicating the coordinate of the aperture blade to be moved is not limited to the above-mentioned "aperture left, +5" and the like, and may be other voices such as "+5, aperture left" and the like.

[0111] The microphone 150 collects the movement instruction word MIW and outputs an electrical signal corresponding to the collected movement instruction word MIW to the remote operation table 130. For example, the voice of the user UR collected by the microphone 150 is a relative value relative to the current position of the aperture blade. The voice recognition function 151 recognizes the aperture blade of the moving object based on the voice of the user UR, that is, the movement instruction word MIW. Specifically, the voice recognition function 151 recognizes the configuration of the aperture blade of the control object of the voice movement control processing and the relative value of the aperture blade of the moving destination based on the movement instruction word MIW of the user UR. The voice recognition function 151 outputs the aperture movement instruction to the movement amount calculation function 153.

[0112] The processing circuit 145 calculates the movement amount of the moving object based on the aperture movement instruction through the movement amount calculation function 153. The movement amount calculation function 153 calculates the movement amount in the same way as in the embodiment, so the description is omitted. At this time, the system control unit 11 moves the aperture blade of the moving object according to the calculated movement amount. That is, the system control unit 11 Fig.10 As shown, the X-ray aperture device 1 b is controlled so that the aperture blade to be moved is moved to the position of the movement destination based on the recognized relative value. Fig.10 The shadow SR in the figure corresponds to the area where the X-rays are shielded by the X-ray aperture (shielded area). Figure 3 The voice of user UR in step S304 is different from that in the implementation mode and is the same as the implementation mode, so the description of the voice movement control processing is omitted.

[0113] In the X-ray diagnosis device 100 involved in this modification, the voice of the user UR collected by the microphone 150 is a relative value relative to the current position of the aperture blade. Therefore, according to the X-ray diagnosis device 100 involved in the third modification, the movement destination of the aperture blade can be more easily specified by voice, and the operability of the aperture operation can be improved. Other effects are the same as those in the embodiment, so the description is omitted.

[0114] (Fourth Modification)

[0115] This modification uses the diagnostic bed 5 as the control target. At this time, the system control unit 11 controls the diagnostic bed 5 so as to move the diagnostic bed 5 to a position corresponding to the recognized numerical value. Fig.1114 is a diagram showing an example of an overview of the process of the voice movement control processing involved in this variant. In this variant, the user UR says "diagnostic bed voice operation" as a start word. In addition, the start word of the voice movement control processing is not limited to the above-mentioned "diagnostic bed voice operation", as long as it is a voice with the intention of operating the diagnostic bed 5 by voice, such as "voice operation, diagnostic bed", or other voices. In addition, other voices may also be words associated with the words used by the doctor to instruct the technician to operate the diagnostic bed 5. In the voice movement control processing in this variant, the movement of the diagnostic bed 5 is controlled. At this time, the current position information of the diagnostic bed 5 is appropriately updated corresponding to the X-ray photography of the subject P, and stored in the memory 143.

[0116] In this variation, after saying "diagnostic bed voice operation", the user UR says the coordinates of the center position of the moving destination in the X-ray image XI (for example, in the order of x coordinate, y coordinate). Fig.11 As shown, when the position coordinates (30, 30) in the X-ray image XI before the center position movement action is set as the center position in the next X-ray photography, the voice spoken to indicate the coordinates of the center position is, for example, "bed movement, 30, 30" etc. In addition, the voice spoken to indicate the coordinates of the center position is not limited to the above-mentioned "bed movement, 30, 30" etc., and may be, for example, "30, 30, bed movement" etc.

[0117] The microphone 150 collects the movement instruction word MIW and outputs an electrical signal corresponding to the collected movement instruction word MIW to the remote operation table 130. The voice recognition function 151 recognizes the numerical value representing the center position of the X-ray irradiation range based on the voice of the user UR, that is, the movement instruction word MIW. The voice recognition function 151 outputs the coordinates representing the center position as the diagnosis bed movement instruction to the movement amount calculation function 153.

[0118] The processing circuit 145, through the movement amount calculation function 153, receives the diagnostic bed movement instruction as an opportunity, and obtains the current position information and position coordinate correspondence table of the diagnostic bed 5 as the moving object from the memory 143. Next, the movement amount calculation function 153 uses the current position information, the position coordinate correspondence table and the coordinates of the moving destination (center position) to calculate the movement amount of the diagnostic bed 5. The movement amount calculation function 153 outputs the calculated movement amount to the system control unit 11. At this time, the system control unit 11 moves the diagnostic bed 5 as the moving object according to the calculated movement amount. That is, the system control unit 11 controls the diagnostic bed 5 according to the position corresponding to the recognized numerical value among the multiple numerical values ​​displayed on the display unit 10 together with the X-ray image (the coordinates of the moving object at the moving destination). In other words, the system control unit 11 controls the diagnostic bed 5 in such a way that the position corresponding to the recognized numerical value becomes the center position of the irradiation range.

[0119] like Fig.11 As shown, in this variant, the field of view size is not changed, but the field of view position is moved. In other words, the voice movement control processing in this variant corresponds to: according to the voice (coordinates) of the user UR, the center position in the X-ray image XI is changed while maintaining the field of view size, that is, the X-ray irradiation range is moved parallel by moving the diagnostic bed 5. Figure 3 The voice (starting word) of the user UR in step S304 and the control object are different from those in the embodiment, and are the same as those in the embodiment and the second modification. That is, the present modification can generate the same X-ray image XI as that in the second modification by moving the diagnostic bed 5 while maintaining the aperture opening of the aperture blades and the position of the aperture blades. Therefore, the description of the voice movement control processing in the present modification is omitted.

[0120] The X-ray diagnostic apparatus 100 according to this modification controls the diagnostic bed 5 so that it moves to a position corresponding to the numerical value recognized by the voice recognition function 151. Specifically, the X-ray diagnostic apparatus 100 according to this modification recognizes the numerical value indicating the center position of the X-ray irradiation range based on the voice of the user UR, and controls the diagnostic bed 5 so that the position corresponding to the recognized numerical value becomes the center position of the irradiation range. Therefore, according to the X-ray diagnostic apparatus 100 according to this modification, the diagnostic bed 5 can be moved without moving the plurality of aperture blades according to the voice of the user UR, so as to change the center position in the X-ray image XI while maintaining the size of the field of view. Therefore, according to the X-ray diagnostic apparatus 100 according to this modification, the diagnostic bed 5 can be operated to the position intended by the user by voice. That is, according to the X-ray diagnostic apparatus 100 according to this modification, by inputting the coordinates by voice, the diagnostic bed 5 can be operated so that the coordinate position becomes the center of the image. Other effects are the same as those of the embodiment and the second modification, so the description is omitted.

[0121] (Fifth Modification)

[0122] In this modification, as the specification of the numerical value by voice, the current position of the diagnostic bed 5 as the control object is used as a relative value of 0 instead of the absolute value. That is, in this modification, the voice spoken by the user UR is different from the embodiment and becomes a word indicating a relative value. The relative value is added with the direction in which the diagnostic bed 5 is moved and the amount of movement in the X-ray image XI. Fig.12 This is a diagram showing an example of an overview of the process of the voice movement control processing involved in this variation.

[0123] In this modification, after saying "diagnostic bed voice operation", the user UR says the moving object (diagnostic bed 5) and the numerical value (relative value) indicating the position of the diagnostic bed 5 at the moving destination. That is, the user's voice includes the relative value relative to the current position of the diagnostic bed 5. The numerical value indicating the relative value of the diagnostic bed 5 at the moving destination is a relative value relative to the numerical value (coordinate value) displayed on the display unit 10. Therefore, the coordinates of the moving destination correspond to the value obtained by adding or subtracting the relative value to the current position of the diagnostic bed 5 as the control object.

[0124] For example, when the bed 5 is moved 10 to the right relative to the X-ray image XI, the speech about the moving object and the relative value is as follows: Fig.11 As shown, it is "bed move, right 10" etc. In addition, the voice about the moving object and relative value is not limited to the above-mentioned "bed move, right 10" etc., for example, it can also be other voices such as "right 10, bed move".

[0125] The microphone 150 collects the movement instruction word MIW and outputs an electrical signal corresponding to the collected movement instruction word MIW to the remote operation table 130. For example, the voice of the user UR collected by the microphone 150 is a relative value relative to the current position of the diagnostic bed 5. The voice recognition function 151 recognizes the relative value of the diagnostic bed 5 at the movement destination of the voice movement control processing based on the voice of the user UR, that is, the movement instruction word MIW. The voice recognition function 151 outputs the diagnostic bed movement instruction to the movement amount calculation function 153.

[0126] The processing circuit 145 calculates the movement amount of the diagnostic bed 5 based on the diagnostic bed movement instruction through the movement amount calculation function 153. The movement amount calculation function 153 calculates the movement amount in the same way as in the embodiment, so the description is omitted. At this time, the system control unit 11 moves the diagnostic bed 5 according to the calculated movement amount. That is, the system control unit 11 Fig.12 As shown, the diagnostic bed 5 is controlled so as to move to the position of the moving destination based on the recognized relative value. Figure 3 The voice (starting word) of the user UR in step S304 and the control object are different from those in the embodiment, and are the same as those in the embodiment. Therefore, the description of the voice movement control process in this variation is omitted.

[0127] In the X-ray diagnostic apparatus 100 of this modification, the voice of the user UR collected by the microphone 150 is a relative value relative to the current position of the diagnostic bed 5. Therefore, according to the X-ray diagnostic apparatus 100 of this modification, the moving destination of the diagnostic bed 5 can be more easily specified by voice, and the operability of the moving action of the diagnostic bed 5 can be improved. Other effects are the same as those of the embodiment, so the description is omitted.

[0128] (Sixth Modification)

[0129] In the embodiment and the first to fifth modified examples, the start word is used to distinguish the movement of the aperture blades from the movement of the diagnostic bed 5, but in this modified example, the start word is commonly set to "voice movement control". At this time, the voice spoken by the user UR in step S304 includes the name of the moving object (for example, the aperture blade or the diagnostic bed 5) in addition to the numerical value. In the case where the voice spoken by the user UR in step S304 does not include the name of the moving object, the system control unit 11 temporarily stops the voice movement control processing for the imaging device 110. At this time, the system control unit 11 outputs a prescribed warning such as "Please say the moving object" through voice or the like.

[0130] According to this modification, by simplifying the start word, the voice movement control process can be started more easily, and the throughput of the examination on the subject P can be improved.

[0131] (Seventh Modification)

[0132] In this modification, in the X-ray image XI, a prescribed image processing is performed on the ROI based on the voice spoken by the user UR. In this modification, the prescribed image processing is set to an enlarged display of the ROI. At this time, the start-up word for starting the image processing related to this modification is set to, for example, "enlargement voice operation". In addition, the start-up word related to the voice-based image processing (hereinafter referred to as voice image processing) is not limited to the above-mentioned "enlargement voice operation", as long as it is a voice with the intention of operating the image processing by voice, such as "voice operation, enlargement", or other voices. In addition, other voices may also be, for example, vocabulary associated with the words used by the physician to instruct the technician to specify the ROI and the enlargement operation of the ROI.

[0133] The microphone 150 collects the voice of performing image processing (such as amplifying voice operation) through the voice of the user UR. Next, the processing circuit 145 recognizes the image processing to be performed by voice based on the user's voice through the voice recognition function 151. In this modification, after saying "amplifying voice operation", the user UR says the numerical value corresponding to the coordinates of the center of the ROI to be enlarged in the X-ray image XI, or the numerical value corresponding to the coordinates of two points corresponding to the two end points of the diagonal of the rectangular ROI when the ROI is a rectangle. In addition, the numerical value is not limited to the coordinates of one or two points, but can also be the coordinates of four points.

[0134] The microphone 150 collects voice corresponding to the numerical value (hereinafter referred to as the processing area word) and outputs an electrical signal corresponding to the voice to the processing circuit 145. The processing circuit 145 performs voice recognition processing on the electrical signal through the voice recognition function 151 and recognizes the numerical value. The voice recognition function 151 outputs the numerical value to the system control unit 11.

[0135] The system control unit 11 sets a region of interest (ROI) in the X-ray image XI based on the recognized numerical value through the setting function 111. When the numerical value corresponds to the coordinates of the center of the ROI to be enlarged, the setting function 111 reads out a specified range stored in the memory 143. The specified range has a magnification corresponding to the size of the ROI, or a pre-set longitudinal / lateral size. The specified range may also be referred to as a specified magnification. The specified range can be appropriately changed by the user's instruction via the input interface 141.

[0136] The setting function 111 sets a specified range with the numerical value as the center as the ROI in the X-ray image XI. That is, when the numerical value recognized by the voice recognition function 151 corresponds to one coordinate, the setting function 111 sets the specified range with the one coordinate as the center as the region of interest (ROI). In addition, when the numerical value corresponds to the coordinates of two points, the setting function 111 sets a rectangle with the coordinates of the two points as the vertices of the diagonal as the ROI. That is, when the numerical value recognized by the voice recognition function 151 corresponds to two coordinates, the setting function 111 sets a rectangle with the line segment connecting the two coordinates as the diagonal as the region of interest (ROI).

[0137] The system control unit 11 performs a prescribed image processing on the region of interest through the image processing function 113. Specifically, the image processing function 113 enlarges the ROI to the image area in the display unit 10 and generates an enlarged image. That is, the image processing function 113 generates an enlarged image after enlarging the set region of interest (ROI) as a prescribed image processing. The display unit 10 displays the X-ray image after the image processing is performed. Specifically, the display unit 10 replaces the displayed X-ray image XI with an enlarged image and displays it. Therefore, in this variant, the ROI is specified according to the voice spoken by the user UR, and the specified ROI is enlarged and displayed. For example, when the coordinates of a point are specified by voice, the enlarged display is performed in a manner such that the specified coordinate position becomes the center of the screen within a prescribed range.

[0138] Based on the above configuration, the X-ray diagnostic apparatus 100 of this modification example displays the numerical value and scale of the coordinate system together with the X-ray image in response to the user speaking the start word, and performs processing to enlarge the ROI (hereinafter referred to as voice image processing) in response to the user speaking the action of the zoom voice operation. Fig.13 Describe the process of speech image processing.

[0139] Fig.13 1 is a flowchart showing an example of the process of speech image processing. As described above, in the speech image processing in this embodiment, the enlargement process of ROI is described as an example. As the content of the enlargement process, a known method can be applied, so the description is omitted. In addition, an example of other image processing is described in the modified example described later.

[0140] (Speech and Image Processing)

[0141] (Step S131)

[0142] The imaging device 110 generates an X-ray image XI by radiating X-rays to the subject P. The display unit 10 displays the X-ray image XI.

[0143] (Step S132)

[0144] If the user UR says a start word such as "amplify voice operation" (step S132: Yes), the microphone 150 collects the voice corresponding to the start word. The microphone 150 converts the collected voice into an electrical signal and outputs it to the remote operation table 130. Next, the process of step S133 is executed. If the user UR does not say the start word (step S132: No), the process of step S140 is executed.

[0145] (Step S133)

[0146] The processing circuit 145 recognizes the start word through the voice recognition function 151. Thus, the voice recognition function 151 determines the content of the image processing in the voice image processing. That is, in this modification, the voice recognition function 151 determines the content of the image processing for the ROI (enlargement processing in this modification) through the recognition of the start word. In response to the recognition of the start word, the system control unit 11 displays a plurality of numerical values ​​NV indicating the position in the X-ray image XI together with the X-ray image XI on the display unit 10. At this time, the display unit 10 may also display a plurality of scales SC corresponding to the plurality of numerical values ​​NV.

[0147] (Step S134)

[0148] If the voice (processing area word) of the user UR is collected with respect to the numerical value NV displayed on the display unit 10 (step S134: Yes), the process of step S135 is executed. If the voice (processing area word) of the user UR is not collected with respect to the numerical value NV displayed on the display unit 10 (step S134: No), the process of step S138 is executed. In addition, the numerical value corresponding to the collected voice is not limited to the numerical value NV displayed on the display unit 10, and may be a value between the numerical values ​​NV displayed on the display unit 10.

[0149] (Step S135)

[0150] The processing circuit 145 recognizes the numerical value corresponding to the voice based on the voice of the user UR collected by the microphone 150 about the numerical value through the voice recognition function 151. Specifically, the voice recognition function 151 determines the coordinates related to the image processing by performing voice recognition processing on the electrical signal corresponding to the voice of the user UR. The system control unit 11 sets the ROI in the X-ray image XI based on the recognized numerical value through the setting function 111.

[0151] (Step S136)

[0152] The system control unit 11 performs image processing on the set ROI through the image processing function 113. Specifically, the image processing function 113 performs enlargement processing to enlarge the ROI in the X-ray image XI to the image area in the display unit 10. The image processing function 113 generates an enlarged image after the ROI is enlarged through the enlargement processing of the ROI.

[0153] (Step S137)

[0154] The system control unit 11 causes the display unit 10 to display the X-ray image after image processing (an enlarged image in this modification). That is, the display unit 10 displays the enlarged image under the control of the system control unit 11.

[0155] (Step S138)

[0156] The system control unit 11 determines whether a predetermined time has passed since the plurality of numerical values ​​NV were displayed on the display unit 10. In addition, the system control unit 11 determines whether a predetermined time has passed since the X-ray image after image processing was displayed. If the predetermined time has passed since the plurality of numerical values ​​NV were displayed on the display unit 10 (step S138: Yes), the process of step S139 is executed. If the predetermined time has not passed since the plurality of numerical values ​​NV were displayed on the display unit 10 (step S138: No), the process after step S134 is repeated.

[0157] (Step S139)

[0158] The system control unit 11 hides the plurality of scales SC and the plurality of numerical values ​​NV displayed together with the X-ray image XI. The processing content in this step is the same as that in step S309, and thus the description thereof is omitted.

[0159] (Step S140)

[0160] If the X-ray imaging of the subject P is completed (step S140: Yes), the audio image processing is completed. If the X-ray imaging of the subject P is not completed (step S140: No), the processing after step S131 is repeated. For example, the end of the X-ray imaging is input by the user through the input interface 141.

[0161] The X-ray diagnosis apparatus 100 according to the seventh modification of the embodiment described above sets a region of interest (ROI) in the X-ray image XI based on the numerical value recognized by the voice recognition function 151, performs a predetermined image processing on the set region of interest (ROI), and displays the X-ray image after the image processing is performed. Specifically, when the recognized numerical value corresponds to one coordinate, the X-ray diagnosis apparatus 100 according to the seventh modification of the embodiment sets a predetermined range with the one coordinate as the center as the region of interest (ROI), and when the recognized numerical value corresponds to two coordinates, sets a rectangle with a line segment connecting the two coordinates as a diagonal line as the region of interest (ROI), generates an enlarged image in which the region of interest (ROI) is enlarged as the predetermined image processing, and displays the generated enlarged image.

[0162] Thus, according to the X-ray diagnostic apparatus 100 involved in the seventh variant of the embodiment, it is possible to set an ROI at a position intended by a user UR such as a physician who is treating a subject P, and to perform image processing on the ROI by voice. Therefore, according to the X-ray diagnostic apparatus 100 involved in this variant, even if both hands of the physician who is the user UR are occupied, image processing can be easily applied to the area intended by the physician. Therefore, according to the X-ray diagnostic apparatus 100 involved in this variant, the operability of the X-ray diagnostic apparatus 100 by the user UR can be improved, and the throughput of the examination on the subject P can be improved.

[0163] (Eighth Modification)

[0164] In this modification, in the X-ray image XI, image processing different from the magnification processing is performed as a predetermined image processing for the ROI based on the speech uttered by the user UR. In order to make the description more specific, it is assumed that image processing (hereinafter referred to as the first image processing) for improving the visual recognition of the internal organs of the subject P is applied in advance to the X-ray image XI. That is, it is assumed that various parameters related to the first image processing (hereinafter referred to as the first parameters) are pre-set according to the internal organs of the imaging object before the user UR or a radiologist or the like examines the subject P using the X-ray diagnostic apparatus 100.

[0165] In addition, in this modification, the image processing applied to the ROI (hereinafter referred to as the second image processing) is set as a process for highlighting the area corresponding to the device in the X-ray image XI. The device is, for example, a catheter, a guide wire, a stent, etc. Before the subject P is examined using the X-ray diagnostic apparatus 100, various parameters related to the second image processing (hereinafter referred to as the second parameters) are pre-set according to the type of device.

[0166] In addition, the second image processing is not limited to the image processing related to the emphasized display (brightness change) of the above-mentioned device (hereinafter referred to as brightness change processing), as long as it is an image processing having a parameter different from the first parameter as the second parameter, it can be any image processing (noise reduction, low frequency emphasis, contour emphasis, high frequency emphasis, etc.). The program for executing the first image processing and the second image processing, the first parameter, and the second parameter are stored in the memory 143.

[0167] The microphone 150 collects the voice of performing the second image processing on the ROI based on the voice of the user UR. The voice used to perform the second image processing is different from that of the seventh variant. For example, it is a voice that indicates the operation of changing the brightness in the ROI through the second image processing, such as a brightness voice operation. In addition, the startup word related to the voice image processing is not limited to the above-mentioned "brightness voice operation", as long as it is a voice with the intention of operating the image processing through voice, such as "brightness operation, zoom in", it can also be other voices. In addition, other voices can also be words related to the words used by the doctor to instruct the technician to specify the ROI and the operation of the second image processing.

[0168] Next, the processing circuit 145 recognizes the second image processing to be performed by voice based on the user's voice through the voice recognition function 151. In this modification, after saying "brightness voice operation", the user UR says the numerical value corresponding to the coordinates of the center of the ROI to be enlarged in the X-ray image XI, or the numerical value corresponding to the coordinates of two points corresponding to the two end points of the diagonal line of the rectangular ROI when the ROI is a rectangle. The collection of the processing area word and the setting of the ROI based on voice are the same as those in the seventh modification, so the description is omitted.

[0169] The system control unit 11 changes the parameters of the image processing applicable to the region of interest set by the setting function 111 to parameters different from the parameters of the image processing outside the region of interest in the X-ray image through the image processing function 113, and performs the prescribed image processing. That is, the image processing function 113 changes the parameters of the image processing applicable to the region of interest from the first parameter to the second parameter, and performs the image processing. Thus, the second image processing is performed on the region of interest. In addition, as the second parameter, a plurality of groups may be set corresponding to the category of the second image processing. At this time, before performing the examination on the subject P, the second parameter applicable to the ROI is selected from a plurality of second parameter groups by the instruction of the user UR via the input interface 141.

[0170] Below, use Fig.13 The flowchart of FIG. 1 illustrates the process of speech image processing in this variant. Fig.13Before the illustrated voice image processing, a first parameter related to the first image processing and a second parameter related to the second image processing are set in advance by an instruction from the user UR via the input interface 141. The set first parameter and second parameter are stored in the memory 143.

[0171] (Speech and Image Processing)

[0172] (Step S131)

[0173] The imaging device 110 generates an X-ray image before image processing (hereinafter referred to as a pre-processing image) by radiating X-rays to the subject P. The system control unit 11 performs the first image processing on the pre-processing image using the first parameter through the image processing function 113, and generates an X-ray image XI after image processing. The display unit 10 displays the generated X-ray image XI.

[0174] (Step S132)

[0175] If the user UR says a start word such as "brightness voice operation" (step S132: Yes), the microphone 150 collects the voice corresponding to the start word. The microphone 150 converts the collected voice into an electrical signal and outputs it to the remote operation table 130. Next, the process of step S133 is executed. If the user UR does not say the start word (step S132: No), the process of step S140 is executed.

[0176] (Step S133)

[0177] The processing circuit 145 recognizes the start word through the voice recognition function 151. Thus, the voice recognition function 151 determines the content of the image processing in the voice image processing. That is, in this modification, the voice recognition function 151 determines the content of the image processing for the ROI (brightness change processing in this modification) through the recognition of the start word. In response to the recognition of the start word, the system control unit 11 displays a plurality of numerical values ​​NV indicating the position in the X-ray image XI together with the X-ray image XI on the display unit 10. At this time, the display unit 10 may also display a plurality of scales SC corresponding to the plurality of numerical values ​​NV.

[0178] The processing contents related to step S134 and step S135 are the same as those in the seventh variant, and thus the description thereof is omitted.

[0179] (Step S136)

[0180] The system control unit 11 performs the second image processing on the set ROI through the image processing function 113. Specifically, the image processing function 113 changes the first parameter to the second parameter and performs the second image processing on the ROI. As a result, the image processing function 113 generates an X-ray image (hereinafter referred to as a processed X-ray image) in which the image processing is different in each region inside the ROI and outside the ROI.

[0181] (Step S137)

[0182] The system control unit 11 causes the display unit 10 to display a processed X-ray image after image processing (in this modification, an X-ray image obtained by subjecting the image processing inside the ROI to different processing than that outside the ROI).

[0183] The processing contents of step S138 , step S139 , and step S140 are respectively the same as those of step S308 , step S309 , and step S310 , and thus description thereof is omitted.

[0184] The X-ray diagnosis apparatus 100 involved in the eighth variant of the embodiment described above sets a specified range with the one coordinate as the center as the region of interest when the numerical value recognized by the voice recognition function 151 corresponds to one coordinate, and sets a rectangle with a line segment connecting the two coordinates as a diagonal line as the region of interest when the recognized numerical value corresponds to two coordinates, changes the parameters of the image processing applied to the region of interest to parameters (second parameters) different from the parameters (first parameters) of the image processing (first image processing) outside the region of interest in the X-ray image, and performs the specified image processing (second image processing).

[0185] Thus, according to the X-ray diagnosis apparatus 100 involved in this modification, it is possible to specify the ROI by voice, and perform image processing only within the specified ROI by changing from the first image processing to the second image processing. According to the X-ray diagnosis apparatus 100 involved in this modification, for example, it is possible to set the image processing parameters (first parameters) that can observe the internal organs outside the ROI and set the image processing parameters (second parameters) that can emphasize the equipment inside the ROI to perform image processing and display the X-ray image after image processing. Other effects are the same as those of the seventh modification, so the description is omitted.

[0186] (First application example)

[0187] This application example integrates the seventh variant with the eighth variant. Therefore, the startup word in this application example is, for example, a word such as a voice image processing operation. Moreover, in this application example, after the startup word is spoken, that is, in step S134, the word spoken becomes a word that expresses the intention of magnification or brightness change in addition to the numerical value corresponding to the coordinates of the center of the ROI, or when the ROI is a rectangle, the numerical value corresponding to the coordinates of the two points corresponding to the two end points of the diagonal of the rectangular ROI. The effect in this application example is the same as that of the seventh variant and the eighth variant, so the description is omitted.

[0188] (Second application example)

[0189] This application example appropriately combines the above-mentioned implementation, the first to eighth variations, and the first application example. As a result, this application example can perform operations of multiple aperture blades, the diagnostic bed 5, or image processing according to the intention of the user UR. In this application example, in response to the action of saying the start word in step S132, the processing of the implementation, the first to eighth variations is performed. The effects in this application example are the same as those of the implementation, the first variation, the eighth variation, and the first application example, so the description is omitted.

[0190] In the case where the technical idea in the present embodiment is realized by an X-ray imaging control method, the X-ray imaging control method has the following steps: performing X-ray imaging of a subject P by an imaging system 110 having an X-ray tube 1a for generating X-rays, an X-ray aperture device 1b for limiting the irradiation range of X-rays, an X-ray detection unit 3 for detecting X-rays, and a diagnostic bed 5 on which the subject P irradiated with X-rays is placed, generating an X-ray image XI, displaying a plurality of numerical values ​​indicating positions in the X-ray image XI together with the X-ray image XI, recognizing a numerical value corresponding to the voice based on the voice of the user UR collected about the numerical value, and controlling the imaging system 110 according to the position corresponding to the recognized numerical value among the plurality of numerical values. The processing process corresponding to the X-ray imaging control method corresponds to the process of voice movement control processing or voice image control processing, and therefore the description thereof is omitted. In addition, the effects achieved by the X-ray imaging control method are the same as those of the embodiment, the first to eighth modified examples, the first application example, and the second application example, and therefore the description thereof is omitted.

[0191] (Third application example)

[0192] This application example displays the voice of the user UR recognized by the voice recognition function 151 and / or the numerical value recognized by the voice recognition function 151 on the display unit 10. That is, the display unit 10 in this application example displays the characters and / or numbers in the movement indicator word MIW. Figure 3 The processing in this application example is implemented in step S305 in .

[0193] The processing circuit 145 performs speech recognition processing on the electrical signal corresponding to the speech of the user UR collected via the microphone 150 through the speech recognition function 151. The speech recognition function 151 stores the recognition result related to the speech of the user UR in the memory 143. The recognition result includes, for example, the speech of the user UR recognized by the speech recognition function 151 and / or the numerical value recognized by the speech recognition function 151.

[0194] The system control unit 11 displays the recognition result of the user UR's voice on the display unit 10. That is, the display unit 10 displays the recognized voice of the user UR and / or the recognized numerical value. At this time, the display unit 10 may also display the user UR's voice and / or the recognized numerical value in the order recognized by the voice recognition function 151. That is, the display unit 10 may also display the recognition result of the user UR's voice in real time in the order in which the voice is spoken.

[0195] Fig.14 1 is a diagram showing an example of display before and after the user UR says "aperture left 15" as the movement instruction word MIW. Fig.14 As shown, before the movement indicator MIW is spoken, nothing is displayed in the area UDA for displaying the recognition result of the user UR's speech, that is, the movement indicator MIW (hereinafter referred to as the speech display area). Fig.14 As shown in FIG. 1 , if the movement instruction word MIW is spoken, the display unit 10 displays “iris left 15” as the movement instruction word MIW as the recognition result of the user UR’s voice in the speech display area UDA.
