Description

[Technical field]

[0001] The embodiments disclosed in the present specification and the like include a medical image diagnostic apparatus and medical image diagnosis method Regarding. [Background technology]

[0002] In interventional radiology (IVR), a catheter or puncture needle is inserted into the body while observing the state of the body in real time using a medical imaging diagnostic device (X-ray diagnostic device, ultrasound diagnostic device, X-ray computed tomography device, magnetic resonance imaging device, etc.), and the target area is treated. In IVR, the preset function of the medical imaging diagnostic device is used. This preset function is a function in which multiple settings of the medical imaging diagnostic device are each registered as a preset, and the surgeon selects a desired preset from among them at a desired timing to set the medical imaging diagnostic device to a setting corresponding to the selected preset. Conventional preset functions include those that assign a preset number to each setting and manage it, and those that manage thumbnail images showing the contents of each setting.

[0003] However, the conventional preset function has the following problems, for example.

[0004] For example, in the case of a preset function that assigns a preset number to each setting and manages them, the surgeon must remember which number corresponds to which setting. As the number of preset numbers increases, the burden on the surgeon increases. Even in the case of a preset function that manages thumbnail images showing the contents of each setting, the surgeon must select a preset that matches the current situation while performing the procedure, which places a heavy burden on the surgeon.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, a medical image diagnostic apparatus according to an embodiment will be described in detail with reference to the drawings. The medical image diagnostic apparatus according to the embodiment is used, for example, to monitor a patient during surgery. In the following description, parts with the same reference numerals perform the same operation, and duplicated descriptions will be omitted as appropriate.

[0010] (First embodiment) As the medical image diagnostic apparatus according to the first embodiment, an X-ray diagnostic apparatus used during surgery will be described as an example.

[0011] Fig. 1 is a block diagram showing the configuration of an X-ray diagnostic system including an X-ray diagnostic apparatus 1 according to a first embodiment. As shown in Fig. 1, the X-ray diagnostic system includes an X-ray diagnostic apparatus 1, an optical imaging device 40, a voice input device 41, and a surgery information management device 42. In the following, for the sake of concrete explanation, a case will be described in which the X-ray diagnostic apparatus 1 is an X-ray diagnostic apparatus for cardiovascular disease having two imaging systems with a biplane structure.

[0012] The X-ray diagnostic apparatus 1 includes an imaging unit 2, a high-voltage generator 3, a drive unit 4, a bed device 5, an operation unit 8, a memory circuit 31, an input interface circuit 33, a display 351, a communication interface circuit 36, and a processing circuit 37. The memory circuit 31, the input interface circuit 33, the display 351, the communication interface circuit 36, and the processing circuit 37 are built into, for example, a console device 30. The imaging unit 2 includes a first imaging system including a first X-ray tube 15, a first collimator 16, a first X-ray detector 17, and a first support mechanism 19, and a second imaging system including a second X-ray tube 25, a second collimator 26, a second X-ray detector 27, and a second support mechanism 29. The first support mechanism 19 and the second support mechanism 29 are also called a C-arm mechanism and an Ω-arm mechanism, respectively, based on their shapes. Moreover, the movement direction of the first support mechanism 19 along the C-shape of the C-arm mechanism is referred to as the "C direction", and the movement direction of the second support mechanism 29 along the Ω-shape is referred to as the "Ω direction".

[0013] The high voltage generator 3 has electric circuits such as a transformer and a rectifier, a high voltage generator, and an X-ray control device. The high voltage generator has a function of generating a high voltage to be applied to the first X-ray tube 15 and the second X-ray tube 25, and a filament current to be supplied to the first X-ray tube 15 and the second X-ray tube 25. The high voltage generator 3 controls the output voltage according to the X-rays irradiated by the first X-ray tube 15 and the second X-ray tube 25. The high voltage generator 3 may be of a transformer type or an inverter type.

[0014] The first X-ray tube 15 and the second X-ray tube 25 are vacuum tubes that generate X-rays by irradiating thermoelectrons from a cathode (filament) to an anode (target) by application of a high voltage from the high voltage generator 3 and supply of a filament current. X-rays are generated when the thermoelectrons collide with the target. The first X-ray tube 15 and the second X-ray tube 25 include, for example, a rotating anode type X-ray tube that generates X-rays by irradiating a rotating anode with thermoelectrons. Note that the type of the first X-ray tube 15 and the second X-ray tube 25 is not limited to the rotating anode type, and any type of X-ray tube can be used.

[0015] The first collimator 16 and the second collimator 26 are provided in front of the X-ray radiation window in the first X-ray tube 15 and the second X-ray tube 25, respectively. The first collimator 16 and the second collimator 26 have four aperture blades made of metal plates such as lead. The aperture blades are driven by a driving device (not shown) according to the region of interest input by the operator via the input interface circuit 33, for example. The first collimator 16 and the second collimator 26 adjust the region where the X-rays are blocked to an arbitrary size by sliding the aperture blades with the driving device. With the adjusted aperture blades, the first collimator 16 and the second collimator 26 block the X-rays outside the opening region. As a result, the first collimator 16 and the second collimator 26 narrow down the X-rays generated by the first X-ray tube 15 and the second X-ray tube 25, respectively, so that they are irradiated onto the region of interest of the subject (patient) P.

[0016] The first X-ray detector 17 and the second X-ray detector 27 detect X-rays generated by the first X-ray tube 15 and the second X-ray tube 25, respectively. The first X-ray detector 17 and the second X-ray detector 27 are, for example, flat panel detectors (hereinafter referred to as FPDs). The FPDs have a plurality of semiconductor detection elements. There are a direct conversion type semiconductor detection element that directly converts X-rays into an electric signal, and an indirect conversion type semiconductor detection element that converts X-rays into light by a phosphor and converts the light into an electric signal. Either type may be used for the FPD. The electric signal generated by the plurality of semiconductor detection elements in response to the incidence of X-rays is output to an analog to digital converter (hereinafter referred to as A / D converter) not shown. The A / D converter converts the electric signal into digital data. The A / D converter outputs the digital data to a processing circuit 37. Note that an image intensifier may be used as the first X-ray detector 17 and the second X-ray detector 27.

[0017] The drive unit 4 is controlled by the processing circuit 37 and drives the first support mechanism 19, the second support mechanism 29, and the bed device 5. For example, the drive unit 4 supplies a drive signal corresponding to a control signal from the processing circuit 37 to the first support mechanism 19, causing the first support mechanism 19 to slide in the C direction and rotate in a direction perpendicular to the C direction. The drive unit 4 supplies a drive signal corresponding to a control signal from the processing circuit 37 to the second support mechanism 29, causing the second support mechanism 29 to slide in the Ω direction and rotate in a direction perpendicular to the Ω direction. The drive unit 4 also supplies a drive signal corresponding to a control signal from the processing circuit 37 to the bed device 5, causing the table top 5a to move up and down and in the longitudinal direction.

[0018] The bed device 5 includes a top board 5a on which a subject P to be imaged is placed and moved, and a base 5b that supports the top board 5a.

[0019] The image generating circuit 6 generates projection data based on the outputs from the first X-ray detector 17 and the second X-ray detector 27 .

[0020] The storage circuit (memory) 31 is a storage device such as an HDD (Hard disk Drive), an SSD (Solid State Drive), or an integrated circuit storage device that stores various information, or is a circuit that combines a plurality of these storage devices. The storage circuit 31 stores, for example, projection data, image data, and programs corresponding to various functions that are read and executed by the processing circuit 37. The storage circuit 31 may be a drive device that reads and writes various information between a portable storage medium such as a CD (Compact Disc), a DVD (Digital Versatile Disc), or a flash memory, or a semiconductor memory element such as a RAM (Random Access Memory), in addition to an HDD or SSD. The storage circuit 31 may be in an external storage device connected via a network. Furthermore, when the storage unit 23 includes a plurality of storage devices, some of the storage devices may be storage devices connected via a network.

[0021] The memory circuitry 31 also stores a preset information management table. Here, the "preset" includes at least one of the settings of the positional relationship of the imaging unit 2 of the X-ray diagnostic apparatus 1, the imaging method, the arrangement of the display unit 35 of the X-ray diagnostic apparatus 1, and the display layout of the display unit 35 of the X-ray diagnostic apparatus 1. The "preset information" is information that manages a preset related to the settings of the X-ray diagnostic apparatus 1, a treatment procedure for surgery in which the X-ray diagnostic apparatus 1 is used, and a situation of the treatment procedure in which the preset is used (selected) in association with each other. Here, the "situation of the treatment procedure (also simply called "situation")" is information that indicates the stage in which the situation of the treatment procedure is during the surgery. The situation of the treatment procedure may be information at the time when a certain event occurs (i.e., instantaneous information), or may be information for a certain period of time, such as "currently in a situation to move the catheter."

[0022] The preset information can be created using a history of presets in past surgeries using the X-ray diagnostic apparatus 1, a history of presets in past surgeries using other X-ray diagnostic apparatuses 1, etc. The preset information can also be created and managed for each surgeon (doctor) or each treatment procedure as necessary. Furthermore, the preset information can also be automatically created during the surgery using, for example, a preset used in the first half of the currently performed treatment procedure, the status of the treatment procedure when the preset was used, and information on the treatment procedure acquired from the surgery plan.

[0023] FIG. 2 is a diagram showing an example of a preset information management table stored in the storage circuitry 31. As shown in FIG. 2, the preset information management table is a table that defines and manages a plurality of preset information items each having a management number "No." attached thereto. Each preset information item includes a preset related to the setting of the X-ray diagnostic apparatus 1, a treatment procedure in which the X-ray diagnostic apparatus 1 is used, and a situation of the treatment procedure in which the preset is used. For example, preset information 1 with a management number "1" attached thereto is defined as information including "cerebral aneurysm coil embolization" as a "treatment procedure", "start of catheter insertion" as a "situation", "angle is biplane reference position", and "adjust the catheter insertion position to the center of the screen in the horizontal direction" as a "preset". The preset information management table shown in FIG. 2 and FIG. 3 described later has a column of "User ID" and manages preset information for each user (operator). In the "User ID" column, preset information with "default" attached thereto is information set as a recommended value (or initial value), and preset information with "A0001" attached thereto is information set for the user corresponding to the ID. Furthermore, the preset information management table is not limited to the examples shown in FIGS. 2 and 3, and a preset information management table that does not have the column for "User ID" and uniformly manages preset information using recommended values ​​may also be used.

[0024] Fig. 3 is a diagram showing another example of the preset information management table stored in the memory circuitry 31. In the preset information management table shown in Fig. 3, for example, preset information 1 with management number "100" is defined as information including "cerebral aneurysm coil embolization" as "treatment procedure", "cerebral aneurysm analysis" as "situation", and "retract the monitor to a position that will not get in the way in preparation for injection of contrast agent" as "preset". These preset information management tables are used when selecting at least one proposed preset according to the situation of the treatment procedure in the preset proposal process described later.

[0025] The storage circuitry 31 also stores a preset history information management table. Here, the preset history information is information that manages a preset actually used in a current treatment procedure using the X-ray diagnostic apparatus 1, the current treatment procedure, and the status of the treatment procedure at the time of the used preset in association with each other. Furthermore, the preset history information may include correction information. The correction information is information that indicates the content of correction when an operator subsequently corrects the settings of the X-ray diagnostic apparatus 1 according to a selected preset and uses the X-ray diagnostic apparatus 1.

[0026] The preset history information is created in real time using the current status of the treatment procedure determined by the processing circuitry 37 during surgery using the X-ray diagnostic apparatus 1. Therefore, the preset history information management table is updated every time new preset history information is created. In addition, the preset history information can also include supplementary information such as information about the current surgeon and time information (for example, time information indicating the progress of the treatment procedure from a reference time point) as necessary.

[0027] FIG. 4 is a diagram showing an example of a preset history information management table stored in the storage circuitry 31. As shown in FIG. 4, the preset history information management table is a table that defines and manages a plurality of preset history information with a management number "No." attached. Each preset history information includes a preset related to the setting of the X-ray diagnostic apparatus 1, a procedure in which the medical image diagnostic apparatus is used, and a situation of the treatment procedure in which the preset is used. For example, preset information 1 with a management number "1" is defined as information including "cerebral aneurysm coil embolization" as a "treatment procedure", "start of catheter insertion" as a "situation", "angle is biplane reference position" as a "preset", "adjust the catheter insertion position to the center of the screen in the horizontal direction", and "adjust the catheter insertion position to the bottom 1 / 3 of the screen" as a "correction information". This preset history information management table is used when selecting at least one proposed preset according to the situation of the treatment procedure in a preset proposal process described later. The preset history information management table shown in FIG. 4 has a column of "User ID" corresponding to the preset information management tables shown in FIG. 2 and FIG. 3, and manages preset information for each user. Naturally, if the preset information management table shown in FIG. 2 and FIG. 3 does not have a column for “User ID” and manages preset information uniformly using recommended values, the preset history information management table will also not have a column for “User ID”.

[0028] The storage circuitry 31 also stores at least one proposed preset judgment rule. Here, the proposed preset judgment rule defines a judgment criterion for whether or not to execute a preset proposal in a preset proposal process described later, such as "proposing a preset that has a usage history of a reference number of times (e.g., three times) or more." The proposed preset judgment rule can be created using a preset history in a past operation using the X-ray diagnostic device 1, a preset history in a past operation using another X-ray diagnostic device 1, or the like. The proposed preset judgment rule can also be dynamically created and updated by the information management function 37c through learning using a preset history information management table of the current treatment procedure. Furthermore, the proposed preset judgment rule can be, for example, a rule created in advance for the first half of the operation, and a rule created dynamically through learning using a preset history information management table of the current treatment procedure from the middle of the operation. The proposed preset judgment rule may be created and managed for each specific entity, such as each surgeon (doctor) or each hospital.

[0029] The memory circuitry 31 also records images of the operating room transferred from the optical imaging device 40, audio data transferred from the audio input device 41, and surgery information transferred from the surgery information management device .

[0030] The input interface circuit 33 receives various input operations from the operator, converts the received input operations into electrical signals, and outputs the electrical signals to the processing circuit 37. For example, the input interface circuit 33 receives from the operator an operation for operating at least one of the imaging unit 2 and the bed device 5, an X-ray condition for generating X-rays, and a condition for image processing executed by the image processing function 37b. As the input interface circuit 33, for example, a mouse, a keyboard, a trackball, a switch, a button, a joystick, a foot switch, a touch pad, a touch panel display, and the like can be appropriately used. The input interface circuit 33 is mounted on, for example, the console device 30 installed in an operation room different from the examination room.

[0031] In this embodiment, the input interface circuit 33 is not limited to one having physical operation parts such as a mouse, a keyboard, a trackball, a switch, a button, a joystick, a touchpad, and a touch panel display. For example, an example of the input interface circuit 33 includes an electrical signal processing circuit that receives an electrical signal corresponding to an input operation from an external input device provided separately from the device and outputs the electrical signal to the processing circuit 37. The input interface circuit 33 may be configured as a tablet terminal or the like capable of wireless communication with the processing circuit 37.

[0032] The display unit 35 is composed of a display 351 that displays medical images g1 and the like, an internal circuit that supplies a display signal to the display 351, and peripheral circuits such as connectors and cables that connect the display 351 and the internal circuit. The internal circuit generates display data by superimposing additional information such as subject information and projection data generation conditions on the image data. Next, the internal circuit performs D / A conversion and TV format conversion on the obtained display data. The internal circuit displays the display data that has been subjected to these conversions on the display 351 as a medical image. In addition, the display unit 35 displays a GUI (Graphical User Interface) and the like for receiving various operations from the operator.

[0033] For example, a liquid crystal display (LCD), a cathode ray tube (CRT) display, an organic electroluminescence display (OELD), a plasma display, or any other arbitrary display can be appropriately used as the display 351. The display 351 may be a desktop type, or may be configured as a tablet terminal or the like capable of wireless communication with the processing circuit 37.

[0034] The communication interface circuit 36 ​​is connected to an external device via a network. The communication interface circuit 36 ​​performs data communication with the external device via the network. The external device is, for example, a medical image management system (PACS (Picture Archiving and Communication System) which is a system for managing data of various medical images, an electronic medical record system for managing electronic medical records to which medical images are attached, etc. Note that the standard for communication with the external device may be any standard, and an example of such a standard is DICOM (Digital Imaging and COmmunications in Medicine).

[0035] The communication interface circuit 36 ​​is also connected to external devices, such as an optical imaging device 40, a voice input device 41, and a surgery information management device 42, via a network. The communication interface circuit 36 ​​receives images of the operating room from the optical imaging device 40, voice data from the voice input device 41, and surgery plan information including information such as patient information, surgeon information, and information related to treatment procedures from the surgery information management device 42, via the network N. The received images of the operating room, voice data, and surgery plan information are sequentially stored in the memory circuit 31, for example.

[0036] The processing circuitry 37 controls the operation of the entire X-ray diagnostic apparatus 1 in response to an electrical signal of an input operation output from the operation unit 8 or the input interface circuitry 33. For example, the processing circuitry 37 has, as hardware resources, processors such as a CPU (Central Processing Unit), an MPU (Micro Processing Unit), and a GPU (Graphics Processing Unit), and memories such as a ROM (Read Only Memory) and a RAM (Random Access Memory).

[0037] Various processing functions executed in the processing circuitry 37 are stored in the memory circuitry 31 in the form of programs executable by a computer. The processing circuitry 37 is a processor that realizes a function corresponding to each program by reading and executing the programs from the memory circuitry 31. In other words, each circuit that has read each program has a function corresponding to the read program.

[0038] Specifically, the processing circuit 37 executes the control function 37a, the image processing function 37b, the information management function 37c, and the judgment function 37d by a processor that executes a program expanded in the memory. The processing circuit 37 that executes the control function 37a, the image processing function 37b, the information management function 37c, and the judgment function 37d corresponds to a control unit, an information management unit, and a judgment unit. The control function 37a, the image processing function 37b, the information management function 37c, and the judgment function 37d are not limited to being realized by a single processing circuit. A processing circuit may be configured by combining multiple independent processors, and the control function 37a, the image processing function 37b, the information management function 37c, and the judgment function 37d may be realized by each processor executing a program.

[0039] In addition, the processing circuit 37 may be realized by a processor such as an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), other Complex Programmable Logic Devices (CPLDs), or Simple Programmable Logic Devices (SPLDs).

[0040] The processing circuitry 37 uses a control function 37a to control the driving unit 4, the high voltage generator 3, the first collimator 16, the second collimator 26, the memory circuitry 31, the display unit 35, the image processing function 37b, the information management function 37c, the judgment function 37d, and the like, based on an input operation received from an operator via the operation unit 8 or the input interface circuitry 33. Specifically, the control function 37a reads out a control program stored in the memory circuitry 31, expands it on the memory in the processing circuitry 37, and controls each part of the X-ray diagnostic apparatus 1 according to the expanded control program.

[0041] The control function 37a performs control related to at least one preset determined in a treatment procedure support process described later. For example, the control function 37a causes the display unit 35 to display at least one preset determined to be proposed in a preset suggestion process (hereinafter, referred to as a "proposed preset"). In addition, the control function 37a performs control related to settings of the X-ray diagnostic apparatus 1 based on a proposed preset selected by an operator from among the at least one proposed preset.

[0042] The processing circuitry 37 performs image processing such as filtering on the projection data from the image generating circuitry 6 using the image processing function 37b to generate image data. The image data corresponds to medical image data including fluoroscopic images and photographed images of the subject P. The image processing function 37b performs synthesis processing, subtraction processing, and the like using the image data. The generated image data is output to the memory circuitry 31 and the display unit 35.

[0043] The processing circuitry 37 creates and updates a preset history information management table by the information management function 37c. For example, the information management function 37c creates and updates the preset history information management table by associating a preset selected during the current surgery, a state of a treatment procedure determined by the determination function 37d at the time of selecting a preset, and a correction instruction for the selected preset, and writing the information in real time to the memory circuitry 31.

[0044] The processing circuitry 37 uses the determination function 37d to determine the status of the treatment procedure in real time based on the status information related to the treatment procedure.

[0045] Here, the situation information related to a treatment procedure (hereinafter simply referred to as "situation information") is information used to determine the situation during the treatment procedure. The situation information is, for example, information such as a medical image acquired by the X-ray diagnostic device 1 during the treatment procedure, a three-dimensional image registered with the medical image acquired during the treatment procedure, an image of an operating room acquired by the optical imaging device 40, and audio data acquired by the audio input device 41. Note that the three-dimensional image registered with the medical image can utilize volume data acquired by other modalities such as an X-ray CT device, an MRI device, an ultrasound diagnostic device, or a nuclear medicine diagnostic device, a three-dimensional image created in a schematic manner, etc.

[0046] More specifically, the judgment function 37d judges the feature information of the situation information such as medical images, images from the operating room, and audio data acquired during the treatment procedure, and judges the current situation of the treatment procedure based on the feature information. Here, the feature information is information such as what, where, in what positional relationship, and in what state.

[0047] For example, when the situation information is a medical image acquired by the X-ray diagnostic apparatus 1 during a treatment procedure, the feature information is information such as the position (spatial coordinates), orientation (posture), size, position information regarding the anatomical structure (e.g., the catheter is in the left atrium), and positional relationship with other objects (e.g., the catheter is located 3 cm in front of the mitral valve) of the objects included in the medical image (catheter, balloon, coil, stent, clip, anatomical landmark, treatment site, etc.). Here, the anatomical landmark means a predefined anatomical position such as the center of the left eyeball, the right pulmonary apex, the aortic valve, etc.

[0048] Also, for example, when the situation information is an image of an operating room acquired by the optical imaging device 40 during a treatment procedure, the feature information is information such as the position (spatial coordinates), orientation (posture), size (or physique), behavior (movement), positional relationship with other objects, etc. of the objects (patient, surgeon, surgical instruments, contrast injection device, etc.) included in the image of the operating room.

[0049] Also, for example, when the situation information is voice data acquired by the voice input device 41 during a medical procedure, the feature information is words acquired by voice recognition.

[0050] Note that feature information of medical images and images from an operating room can be acquired using, for example, object recognition processing, semantic segmentation processing, behavior recognition processing, etc. Also, feature information of voice data can be acquired using voice recognition processing, etc.

[0051] In addition, a part of the determination function 37d may exist on the cloud. For example, the determination of the status of the treatment procedure based on the voice data of the determination function 37d may use a voice recognition service provided via the Internet or the like.

[0052] The processing circuit 37 uses the determination function 37d to determine the situation regarding the treatment procedure in real time based on the feature information of the situation information regarding the treatment procedure. For example, the determination function 37d includes an AI (Artificial Intelligence) model such as a deep neural network that executes object recognition processing and semantic segmentation processing using, for example, medical images, images from an operating room, and audio data as input, and outputs the situation regarding the treatment procedure. Note that the determination function 37d is not limited to the above AI model, and may be, for example, a processing function using an AI model that receives situation information regarding the treatment procedure as input and outputs feature information, and a table in which feature information and situations regarding the treatment procedure are associated with each other.

[0053] The determination function 37d also sends the determined status of the treatment procedure to the information management function 35c. The information management function 35c writes the status of the treatment procedure received from the determination function 37d in a preset history information management table, and successively updates the preset history information management table.

[0054] Moreover, the judgment function 37d judges at least one proposed preset using the preset information management table, the preset history information management table, and the proposed preset judgment rule. For example, the judgment function 37d judges the similarity between the current treatment procedure status and the treatment procedure status included in the preset information management table using the preset history information management table. The judgment function 37d judges whether to propose a preset using the judged similarity and the proposed preset judgment rule. Here, the judgment of the similarity between the current treatment procedure status and the treatment procedure status included in the preset information management table can be judged, for example, by the similarity of the stage of the treatment procedure status transition. In addition, it can also be judged by the similarity between the status information on which the current treatment procedure status judgment is based and the status information on which the treatment procedure status judgment is based included in the preset information management table. Furthermore, it is also possible to judge by an AI model that inputs the status information on which the current treatment procedure status judgment is based and the status information on which the treatment procedure status judgment is based included in the preset information management table, and outputs the similarity. In this embodiment, "similar" means that the similarity is equal to or greater than a reference value.

[0055] In addition, when the determination function 37d determines that a preset should be proposed, the determination function 37d determines at least one proposed preset by using the preset information management table and the preset history information management table. In addition, the determination function 37d modifies the proposed preset by using modification information included in the preset history information management table.

[0056] Here, the proposed preset determined by the determination function 37d is not limited to a preset that realizes a certain setting with fixed parameters, but may be a preset that realizes a dynamic setting whose value changes for each treatment procedure. A specific example of a preset that realizes a dynamic setting whose value changes for each treatment procedure is a preset that sets a "Working Angle." The "Working Angle" is a C-arm angle that is set during surgery planning or during analysis during surgery, which is easy to perform during a procedure performed under X-ray fluoroscopy, such as coil embolization of a cerebral aneurysm. In general, the Working Angle is different each time depending on the direction of the aneurysm, etc. Therefore, for example, when using a preset that says "When the treatment procedure situation is coil placement, use the Working Angle," the X-ray diagnostic device 1 is set to use the Working Angle, but the specific angle of the Working Angle is different each time.

[0057] In addition, when the judgment function 37d judges whether or not a preset suggestion is necessary, in addition to the proposed preset judgment rules stored in the memory circuitry 31, a proposed preset judgment rule created by an AI model that inputs current and past preset history information about the surgeon and outputs a proposed preset judgment rule may be used.

[0058] The optical imaging device 40 is, for example, a digital camera that captures images of a room (for example, an operating room) in which the X-ray diagnostic apparatus 1 is installed. The optical imaging device 40 sequentially transfers the captured images of the operating room to the X-ray diagnostic apparatus 1 via the network N.

[0059] The voice input device 41 inputs voice in an operating room, for example, the voice of an operator, and sequentially transfers the voice data to the X-ray diagnostic apparatus 1 via the network N.

[0060] The surgery information management device 42 manages surgery plan information. Here, "surgery plan information" refers to information including the treatment procedure performed in the surgery, the target patient, the surgeon, the date and time of the surgery, tools required for the surgery, etc. The surgery information management device 42 transmits the surgery plan information to the X-ray diagnostic apparatus 1 via the network N.

[0061] [Treatment procedure support processing] Next, a therapeutic procedure support process executed by the X-ray diagnostic apparatus 1 according to this embodiment will be described. The therapeutic procedure support process can be roughly classified into a preset history information generation process and a preset proposal process. In the following, for the sake of specificity, the preset history information generation process and the preset proposal process will be described as an example in which the therapeutic procedure is cerebral aneurysm coil embolization. However, this is merely an example, and any therapeutic procedure involving image observation using the X-ray diagnostic apparatus 1 can be the target of the therapeutic procedure support process.

[0062] [Preset history information generation process] 5 is a flowchart showing the flow of the preset history information generation process. As shown in the figure, when the control function 37a receives a preset selection instruction (step S1), the information management function 37c records the selected preset in the preset history information management table (step S2).

[0063] Next, the information management function 37c judges whether the control function 37a has received an instruction to modify the settings by the preset (step S3). If the control function 37a has received an instruction to modify the settings by the preset (Yes in step S3), the information management function 37c records the contents of the modification instruction received by the control function 37a as modification information in the preset history information management table (step S4). On the other hand, if the control function 37a has not received an instruction to modify the settings by the preset (No in step S3), the process proceeds to step S5.

[0064] Next, the information management function 37c acquires situation information including at least one of the medical images acquired by the X-ray diagnostic apparatus 1, the images of the operating room acquired by the optical imaging device 40, and the audio data acquired by the audio input device 41 (step S5).

[0065] Next, the judgment function 37d judges the status of the current treatment procedure based on the status information acquired by the information management function 37c (step S6).

[0066] For example, the judgment function 37d recognizes a doctor's statement, "I will now insert a catheter," through voice recognition processing using the acquired voice data, and judges that the current status of the treatment procedure is, for example, "catheter insertion has begun."

[0067] Furthermore, for example, the determination function 37d executes human body / object recognition processing and behavior recognition processing using the acquired images of the operating room, and recognizes that a person is holding a catheter, that the person is in a catheter insertion posture, etc. Based on the results obtained by the human body / object recognition processing and behavior recognition processing, the determination function 37d determines that the current status of the treatment procedure is, for example, "catheter insertion start."

[0068] Also, for example, the determination function 37d executes object recognition processing and semantic segmentation processing using the acquired medical image, and determines the position, size, and positional relationship of various objects (catheters, anatomical landmarks, etc.) in the medical image. Based on the results of the object recognition processing, etc., the determination function 37d determines that the status of the current treatment procedure is, for example, "catheter movement."

[0069] In addition, for example, the determination function 37d executes object recognition processing and semantic segmentation processing using the acquired medical image to determine whether or not the catheter has reached the head. If the determination function 37d determines that the catheter has reached the head, it determines that the current treatment procedure status is, for example, "catheter has reached the head."

[0070] In addition, for example, the determination function 37d executes object recognition processing and semantic segmentation processing using the acquired medical image to determine whether the catheter has reached the contrast agent injection position. If the determination function 37d determines that the catheter has reached the contrast agent injection position, it determines that the current treatment procedure status is, for example, "cerebral aneurysm analysis."

[0071] In cerebral aneurysm analysis, a contrast agent is injected from the entrance of the brain and contrast photography is performed to create a 3D image of the cerebral aneurysm. The size and volume of the aneurysm are then calculated based on the generated 3D image, and the method of coil placement in the subsequent process is determined. For example, if the neck (base) of the aneurysm is large, a placement method such as using a stent or balloon to help prevent the coil from protruding is adopted. If a coil is used, the coil filling rate (the ratio of the volume of the aneurysm to the volume of the filled coil) is further calculated using the 3D image.

[0072] Next, the information management function 37c records the status of the current medical procedure determined by the determination function 37d in the preset history information management table (step S7).

[0073] [Preset suggestion processing] Fig. 6 is a flow chart showing the flow of the preset suggestion process. As shown in the figure, the information management function 37c acquires situation information including at least one of the medical image acquired by the X-ray diagnostic device 1, the image of the operating room acquired by the optical imaging device 40, and the voice data acquired by the voice input device 41 (step S11). The judgment function 37d judges the current situation of the treatment procedure based on the situation information acquired by the information management function 37c (step S12). Note that the processes of steps S11 and S12 are the same as the processes of steps S5 and S6.

[0074] Next, the judgment function 37d refers to the preset information management table and judges whether or not there is a situation similar to the judged current treatment procedure situation (step S13). If the judgment function 37d judges that there is at least one situation similar to the current treatment procedure situation in the preset information management table (Yes in step S13), the process proceeds to step S14. On the other hand, if the judgment function 37d judges that there is not at least one situation similar to the current treatment procedure situation in the preset information management table (No in step S13), the processes of steps S11 to S13 are repeatedly executed.

[0075] Next, the determination function 37d determines whether to execute a preset suggestion using the proposed preset judgment rule and the preset history information management table (step S14). For example, assume that the proposed preset judgment rule is "propose a preset with a usage history of three or more times". In this case, the determination function 37d sets a preset corresponding to the situation determined to be similar in step S13 as a candidate preset and determines how many times the candidate preset has been used in the surgery by referring to the preset history information management table. As a result of the determination, if the preset corresponding to the situation determined to be similar in step S13 has been used three or more times in the surgery (Yes in step S14), the process proceeds to step S15. On the other hand, if the preset corresponding to the situation determined to be similar in step S13 has been used for the first or second time in the surgery (No in step S14), the processes of steps S11 to S14 are repeatedly executed.

[0076] Next, the determination function 37d refers to the preset history information management table to determine whether or not there is correction information whose situation is similar to that of the candidate preset (step S15). If the determination function 37d determines that there is correction information whose situation is similar to that of the candidate preset (Yes in step S15), the information management function 37c corrects the candidate preset using the correction information (step S16).

[0077] For example, assume that the candidate preset selected in step S13 is "angle is biplane reference position" and "adjust catheter insertion position to screen center in horizontal direction" corresponding to the preset with management number "1" in the preset information management table shown in FIG. 2. In this case, the determination function 37d refers to the preset history information with management number "1" whose situation is similar to the situation of the candidate preset "catheter insertion start" in the preset history information management table shown in FIG. 3, for example, and determines that correction information "adjust catheter insertion position to bottom 1 / 3 of screen" exists. The information management function 37c uses the correction information to correct "adjust catheter insertion position to screen center in horizontal direction," which is part of the candidate preset, to "adjust catheter insertion position to bottom 1 / 3 of screen." This correction allows the surgeon's tendency to see information further ahead on the medical image to be included in the proposed preset.

[0078] Also, for example, assume that the candidate preset selected in step S13 is the "biplane reference position" corresponding to the preset with the management number "4" in the preset information management table shown in FIG. 2. In this case, the determination function 37d refers to the preset history information of the management number "2" whose situation is similar to the situation "catheter movement" of the candidate preset in the preset history information management table shown in FIG. 4, for example, and determines that the correction information "Bring the FPD as close as possible without touching the patient" exists. The information management function 37c uses the correction information to correct the "biplane reference position" which is a part of the candidate preset to "Bring the FPD as close as possible without touching the patient". This correction allows the proposed preset to include an adjustment to reduce scattered radiation in X-ray fluoroscopy during a treatment procedure.

[0079] Also, for example, assume that the candidate preset selected in step S13 is "biplane reference position" and "move FPD as close as possible without touching the patient" corresponding to the preset with management number "3" in the preset information management table shown in Fig. 2. In this case, the determination function 37d refers to the preset history information with management number "2" whose situation is similar to the situation "catheter movement" of the candidate preset in the preset history information management table shown in Fig. 3, for example, and determines that the correction information "move FPD as close as possible without touching the patient" exists. Since the candidate preset reflects the correction information, the candidate preset is not corrected.

[0080] Also, for example, assume that the candidate preset selected in step S13 is "The inclination of the C-arm is set to a Working Angle that is preset or automatically determined" and "Adjust to the center of the brain with the aneurysm, either the right or left brain" corresponding to the preset with the management number "9" in the preset information management table shown in FIG. 2. In this case, the determination function 37d refers to the preset history information of the management number "6" whose situation is similar to the situation of the candidate preset "coil placement" in the preset history information management table shown in FIG. 3, and determines that the correction information "The horizontal and vertical movements are adjusted around the aneurysm" exists. The information management function 37c uses the correction information to correct "Adjust to the center of the brain with the aneurysm, either the right or left brain" which is part of the candidate preset to "The horizontal and vertical movements are adjusted around the aneurysm".

[0081] Also, for example, assume that the candidate preset selected in step S13 is "Retract the monitor to a position where it will not get in the way in preparation for contrast injection" corresponding to the preset with the management number "100" in the preset information management table shown in FIG. 3. In this case, the determination function 37d refers to preset history information in the preset history information management table that is similar to the status of the candidate preset "coil placement" and determines whether or not correction information exists. If correction information exists, the information management function 37c corrects the candidate preset based on the correction information. On the other hand, if correction information does not exist, the candidate preset is not corrected.

[0082] Also, for example, assume that the candidate preset selected in step S13 is "change to MPR image (orthogonal three-section image) display layout" corresponding to the preset with management number "103" in the preset information management table shown in FIG. 3. In this case, the determination function 37d refers to preset history information in the preset history information management table whose status is similar to the status of the candidate preset "creation of three-dimensional image for cerebral aneurysm analysis" and determines whether or not correction information exists. If correction information exists, the information management function 37c corrects the candidate preset based on the correction information. On the other hand, if correction information does not exist, the information management function 37c does not correct the candidate preset.

[0083] On the other hand, if the determination function 37d determines that there is no modification information corresponding to the candidate preset (No in step S15), the process proceeds to step S17.

[0084] Next, the control function 37a causes the display 351 to present (display) the candidate preset corrected in step S16 when the correction information exists, and the candidate preset determined in step S14 when the correction information does not exist, as a proposed preset (step S17). If necessary, the control function 37a outputs the contents of the proposed preset as audio data from the speaker. The control function 37a also causes the display 351 to present an inquiry about whether the proposed preset needs to be executed, together with the proposed preset. If there are multiple candidate presets, the process of steps S14 to S17 can be performed for each candidate preset, and multiple proposed presets can be presented on the display 351.

[0085] Next, the control function 37a judges whether or not the proposed preset has been selected (whether or not an instruction requiring execution of the proposed preset has been received) (step S18). When an instruction requiring execution of the proposed preset has been input from the input interface circuit 33 ("Yes" in step S18), the control function 37a executes control according to the proposed preset (step S19). For example, when the proposed preset is "adjust the catheter insertion position to the bottom 1 / 3 of the screen", the control function 37a controls the display unit 35 so that the catheter insertion position is the bottom 1 / 3 of the screen on the display 351. Also, for example, when the proposed preset is "change to MPR image (orthogonal three-section image) display layout", the control function 37a controls the image processing function 37b and the display unit 35 so that an MPR image (orthogonal three-section image) is displayed.

[0086] On the other hand, if an instruction requiring execution of the proposed preset is not input from the input interface circuit 33 ("No" in step S18), the processes in steps S11 to S18 are repeatedly executed.

[0087] FIG. 7 is a diagram showing an example of a presentation form of the proposed preset in step S17. In the example of FIG. 7, it is assumed that the proposed preset is the situation "catheter movement (catheter reaches the top end of the screen)" corresponding to the management number "5" in the preset information management table shown in FIG. 2, and the preset is "translate the C-arm following the catheter movement". In this embodiment, for the sake of concrete explanation, it is assumed that the horizontal movement is also automatically performed by translating the first support mechanism 19 (C-arm) or the second support mechanism 29 (Ω-arm). In contrast, the angle of the first support mechanism 19 or the second support mechanism 29 is set by the auto position, and the movement of the field of view in the patient's body axis direction can also be adjusted by sliding the top plate 5a of the bed device 5.

[0088] As shown in Figure 7(a), when the catheter reaches the top of the screen on the medical image displayed on display 351, the judgment function 37d, triggered by the catheter reaching the top of the screen, executes the processing of steps S11 to S16 in Figure 6 and judges the proposed preset "translate the C-arm in parallel to follow the movement of the catheter."

[0089] The control function 37a displays the proposed preset and an inquiry as to whether the proposed preset needs to be executed on the display 351, for example, as shown in FIG. 7(b). When an instruction requiring execution of the proposed preset (selection of "Yes" in FIG. 7(b)) is input from the input interface circuit 33, the control function 37a translates the first support mechanism 19 (C-arm) following the movement of the catheter as control according to the proposed preset corresponding to step S18. As a result, a medical image in which the first support mechanism 19 (C-arm) follows the movement of the catheter is displayed on the display 351, as shown in FIG. 7(c) and FIG. 7(d). On the other hand, when an instruction not requiring execution of the proposed preset (selection of "No" in FIG. 7(b)) is input from the input interface circuit 33, the control function 37a does not update the automatic movement setting.

[0090] Furthermore, after control (setting) according to the proposed preset, if an adjustment based on the results of automatic movement control, such as the Working Angle, is detected, the control function 37a causes the display 351 to display an inquiry as to whether the automatic movement settings need to be updated. When an instruction requiring the update of the automatic movement settings (selection of "Yes" in FIG. 7(e)) is input from the input interface circuit 33, the control function 37a executes the update of the automatic movement settings. On the other hand, when an instruction requiring the update of the automatic movement settings (selection of "No" in FIG. 7(e)) is input from the input interface circuit 33, the control function 37a does not execute the update of the automatic movement settings.

[0091] As described above, the X-ray diagnostic apparatus 1 as a medical image diagnostic apparatus according to this embodiment includes the determination function 37d as a determination unit and the control function 37a as a control unit. The determination function 37d determines the status of the current treatment procedure based on the status information, and determines at least one proposed preset for the settings of the medical image diagnostic apparatus based on the determined status of the current treatment procedure. The control function 37a executes control for the determined at least one preset.

[0092] Therefore, based on the current status of the treatment procedure, at least one preset that is currently or will be required by the surgeon in the treatment procedure can be determined and presented to the surgeon as a suggested preset. Therefore, the surgeon can accurately and quickly select a preset appropriate for the current status of the treatment procedure without having to select a desired preset from buttons or thumbnail images corresponding to multiple presets.

[0093] In surgery and IVR, time is important and efficiency is required. In recent years, the need for efficiency has increased further due to the shortage of medical resources caused by the aging population and work style reforms. According to the X-ray diagnostic device 1 of this embodiment, the burden on the surgeon when using the preset function of the X-ray diagnostic device 1 can be reduced, and the surgeon can be supported to concentrate on his / her own procedure. As a result, further efficiency can be achieved in surgery and IVR.

[0094] Second embodiment The medical image diagnostic apparatus according to the second embodiment will be described taking an ultrasonic diagnostic apparatus used during surgery as an example.

[0095] Fig. 8 is a block diagram showing the configuration of an ultrasound diagnostic system including an ultrasound diagnostic device 100 according to the second embodiment. As shown in Fig. 8, the ultrasound diagnostic system includes the ultrasound diagnostic device 100, an optical imaging device 40, a voice input device 41, a surgery information management device 42, and a vital sign measuring device 43.

[0096] The vital sign measuring device 43 measures vital sign information (heart rate, respiratory rate, blood pressure, body temperature) of the subject P. The vital sign measuring device 43 transfers the measured vital sign information to the ultrasound diagnostic device 100 via the network N. The vital sign measuring device 43 also has an alert function that monitors a numerical value (e.g., blood pressure) included in the vital sign information, and when the value satisfies an alert condition (e.g., falls below a reference value), notifies the operator to that effect.

[0097] The ultrasonic diagnostic apparatus 100 includes an ultrasonic probe 50, a display device (display unit) 51, an input interface circuit 84, and an apparatus main body .

[0098] The ultrasonic probe 50 includes a plurality of piezoelectric transducers, a matching layer provided on the piezoelectric transducers, and a backing material for preventing the propagation of ultrasonic waves backward from the piezoelectric transducers. The ultrasonic probe 50 is detachably connected to the device body 70. The plurality of piezoelectric transducers generate ultrasonic waves based on a drive signal supplied from an ultrasonic transmission circuit 71 in the device body 70. The ultrasonic probe 50 may be provided with buttons that are pressed for various operations such as a freeze operation.

[0099] When ultrasonic waves are transmitted from the ultrasonic probe 50 to the subject P, the transmitted ultrasonic waves are reflected one after another by discontinuous surfaces of acoustic impedance in the internal tissues of the subject P. The reflected ultrasonic waves are received as reflected wave signals (hereinafter referred to as echo signals) by a plurality of piezoelectric transducers of the ultrasonic probe 50. The amplitude of the received echo signal depends on the difference in acoustic impedance at the discontinuous surface where the ultrasonic waves are reflected. When the transmitted ultrasonic pulse is reflected by the surface of a moving blood flow or a heart wall, the echo signal undergoes a frequency shift due to the Doppler effect depending on the velocity component of the moving body in the ultrasonic transmission direction. The ultrasonic probe 50 receives the echo signal from the subject P and converts it into an electric signal. In this embodiment, the ultrasonic probe 50 is an oral probe.

[0100] The device main body 70 is a device that generates an ultrasonic image based on an echo signal received by the ultrasonic probe 50. The device main body 70 has an ultrasonic transmission circuit 71, an ultrasonic reception circuit 73, a B-mode processing circuit 75, a Doppler processing circuit 77, a memory circuit (storage unit) 81, an image memory 82 (also called a cine memory or cache), a display unit 83, an input interface circuit 84, a communication interface circuit 85, and a processing circuit 87, as shown in FIG.

[0101] The ultrasonic transmission circuit 71 is a processor that supplies a drive signal to the ultrasonic probe 50. The ultrasonic transmission circuit 71 includes, for example, a trigger generation circuit, a delay circuit, and a pulser circuit. The trigger generation circuit repeatedly generates a rate pulse for forming a transmission ultrasonic wave at a predetermined rate frequency by a control function 87a in the processing circuit 87. The delay circuit provides each rate pulse with a delay time for each piezoelectric transducer that is required to focus the ultrasonic waves generated from the ultrasonic probe 50 into a beam shape and determine the transmission directivity. The pulser circuit applies a drive signal (drive pulse) to the ultrasonic probe 50 by the control function 87a at a timing based on the rate pulse. The transmission direction from the piezoelectric transducer surface can be arbitrarily adjusted by changing the delay time provided to each rate pulse by the delay circuit.

[0102] The ultrasonic receiving circuit 73 is a processor that performs various processes on the echo signals received by the ultrasonic probe 50 to generate received signals. The ultrasonic receiving circuit 73 has, for example, an amplifier circuit, an A / D converter, a reception delay circuit, and an adder. The amplifier circuit amplifies the echo signals received by the ultrasonic probe 50 for each channel and performs gain correction processing. The A / D converter converts the gain-corrected echo signals into digital signals. The reception delay circuit provides the digital signals with a delay time required to determine the reception directivity. The adder adds multiple digital signals to which a delay time has been provided. The addition process of the adder generates a received signal in which the reflection components from the direction corresponding to the reception directivity are emphasized.

[0103] The B-mode processing circuit 75 is a processor that generates B-mode data based on the reception signal received from the ultrasonic reception circuit 73. The B-mode processing circuit 75 performs envelope detection processing, logarithmic amplification processing, and the like on the reception signal received from the ultrasonic reception circuit 73, and generates data that expresses the signal intensity as brightness (i.e., data acquired by B mode. Hereinafter, referred to as B-mode data). The generated B-mode data is stored in a RAW data memory (not shown) as B-mode RAW data on a two-dimensional ultrasonic scan line.

[0104] The Doppler processing circuit 77 is a processor that generates Doppler waveform data and Doppler data based on the reception signal received from the ultrasonic reception circuit 73. The Doppler processing circuit 77 extracts a blood flow signal from the reception signal, generates Doppler waveform data from the extracted blood flow signal, and generates data in which information such as average velocity, variance, and power is extracted for multiple points from the blood flow signal (i.e., data acquired in Doppler mode. Hereinafter, referred to as Doppler data). The generated Doppler data is stored in a RAW data memory (not shown) as Doppler RAW data on a two-dimensional ultrasonic scan line.

[0105] The image generating circuit 79 generates a GUI for the operator to input various instructions via the input interface circuit 84. The image generating circuit 79 is a processor having a function (scan converter) of generating data of various ultrasound images based on data generated by the B-mode processing circuit 75 and the Doppler processing circuit 77. The image generating circuit 79 includes an internal memory (not shown). The image generating circuit 79 generates two-dimensional ultrasound image data (B-mode image data, color Doppler image data, Doppler waveform image data, etc.) composed of pixels by executing RAW-pixel conversion. The image generating circuit 79 stores the generated ultrasound image data in the storage circuit 81. The image generating circuit 79 executes various image processing such as dynamic range, brightness, contrast, gamma curve correction, and RGB conversion on the generated ultrasound image data.

[0106] The image generating circuitry 79 can also generate volume data consisting of voxels in a desired range by performing an interpolation process or the like on B-mode image data or the like that takes spatial position information into consideration. The image generating circuitry 79 may generate volume data by performing a RAW-voxel conversion including an interpolation process that takes spatial position information into consideration on B-mode RAW data stored in the RAW data memory. The image generating circuitry 79 may also perform a rendering process or a multi-planar reconstruction (hereinafter referred to as MPR) process or the like on various types of volume data to generate a rendering image or an MPR image.

[0107] The storage circuit 81 is realized by, for example, a magnetic or optical storage medium, or a processor-readable storage medium such as an integrated circuit storage device. For example, the storage circuit 81 corresponds to an HDD, SSD, semiconductor memory, etc. that stores various information. In addition to an HDD or SSD, the storage circuit 81 may be a portable storage medium such as a CD, DVD, or flash memory, or a drive that reads and writes various information between the portable storage medium and a semiconductor memory element such as a RAM.

[0108] The memory circuitry 81 stores programs and the like for implementing various functions according to this embodiment. The memory circuitry 81 stores a group of data such as diagnostic information (e.g., patient ID, doctor's findings, etc.), diagnostic protocols, a body mark generating program, and a conversion table that presets the range of color data used for visualization for each diagnostic region. The various data stored in the memory circuitry 81 can also be transferred to an external device via the communication interface circuitry 85 by the control function 87a.

[0109] The storage circuit 81 also stores a preset information management table, a preset history information management table, and at least one proposed preset judgment rule.

[0110] FIG. 9 is a diagram showing an example of a preset information management table stored in the memory circuitry 81. As shown in FIG. 9, for example, preset information 1 with a management number "1" is defined as information including "mitral valve clipping" as a "treatment technique", "approach of clip to valve" as a "situation", and "mid-esophageal mitral valve commissure view (2-chamber view: 60-90°)" and "mid-esophageal aortic valve long axis view (3-chamber view: 100-160°)" as presets. Here, "mitral valve clipping" refers to treating regurgitation by attaching a clip using a catheter to a part where regurgitation occurs due to a disorder of the mitral valve of the heart. Note that the preset information management table shown in FIG. 9 is also exemplified by providing a column of "User ID" to manage preset information for each user (operator) as in FIG. 2 and FIG. 3. Of course, a preset information management table that manages preset information uniformly according to a recommended value without providing a column of "User ID" can also be used.

[0111] Also, for example, preset information 100 with the management number "100" is defined as information including "mitral valve clipping" as the "treatment procedure," "clip attachment" as the "situation," and "suggestion to change alert condition to clip attachment mode" as the "preset."

[0112] Here, the preset "Propose to change the alert condition to the clip attachment mode" will be described. In mitral valve clipping, a clip is attached to the part of the mitral valve where regurgitation occurs to treat the regurgitation. The attachment of this clip prevents a part of the mitral valve from opening, causing a temporary drop in blood pressure. This temporary drop in blood pressure occurs in response to the proper attachment of the clip, and is therefore normal. On the other hand, if this temporary drop in blood pressure satisfies the alert condition, the vital sign measuring device 43 issues an alert to that effect. "Propose to change the alert condition to the clip attachment mode" is a preset that changes the alert condition when the "situation" is "clip attachment" to realize an installation that does not issue an alert for the vital sign measuring device 43 as an external device due to the temporary drop in blood pressure caused by the clip attachment.

[0113] The preset history information management table and at least one proposed preset determination rule are the same as those described in the first embodiment, and therefore description thereof will be omitted.

[0114] In addition, the memory circuit 81 records images of the operating room transferred from the optical imaging device 40, audio data transferred from the audio input device 41, surgical information transferred from the surgical information management device 42, and vital sign information transferred from the vital sign measuring device 43.

[0115] The image memory 82 has, for example, a recording medium such as a semiconductor memory that can be read by a processor. The image memory 82 is realized, for example, by a cache memory. The image memory 82 saves data of various images acquired during a certain period prior to a freeze operation input via the input interface circuit 84. Specifically, in order to perform scrolling display, the image memory 82 stores Doppler waveform image data over a certain period of time from the moment the freeze button is pressed so that the data is not overwritten by other data. The memory circuit 81 and the image memory 82 may be integrated into one storage device.

[0116] The display unit 83 is any display, such as a liquid crystal display, a CRT display, an organic EL display, or a plasma display. The display unit 83 may be incorporated into the device body 70. The display unit 83 may be a desktop type, or may be configured as a tablet terminal or the like capable of wireless communication with the device body 70. The display unit 83 is an example of a display unit.

[0117] The display unit 83 displays various information. For example, the display unit 83 displays ultrasound images generated by the processing circuitry 87, a user interface (GUI) for receiving various operations from the operator, and the like. In a cine display mode, the display unit 83 displays ultrasound images in time series in response to an instruction from the operator via the input interface circuitry 84. In a scroll display mode, the display unit 83 displays Doppler waveform images in time series in response to an instruction from the operator via the input interface circuitry 84. In addition, for example, in a Doppler mode, when a scroll operation is input after a freeze operation is input (scroll display), the display unit 83 displays a Doppler waveform corresponding to at least one corresponding heartbeat in accordance with the direction and amount of the scroll operation.

[0118] The input interface circuit 84 receives various input operations from an operator, converts the received input operations into electrical signals, and outputs the electrical signals to the processing circuit 87. The input interface circuit 84 includes, for example, a mouse, a keyboard, a trackball, a switch, a button, a joystick, a touchpad, and a touch panel display. In the present embodiment, the input interface circuit 84 is not limited to a circuit including physical operation parts such as a mouse, a keyboard, a trackball, a switch, a button, a joystick, a touchpad, and a touch panel display. For example, an example of the input interface circuit 84 includes an electrical signal processing circuit that receives an electrical signal corresponding to an input operation from an external input device provided separately from the input interface circuit 84 and outputs the electrical signal to the processing circuit 87. The input interface circuit 84 may be provided in the device main body 70. The input interface circuit 84 may be configured as a tablet terminal or the like capable of wireless communication with the device main body 70.

[0119] For example, in response to pressing an end button or a freeze button in the input interface circuit 84 (hereinafter referred to as a freeze operation), the ultrasound diagnostic apparatus 100 stops transmitting and receiving ultrasound and goes into a pause state.

[0120] In addition, in response to a freeze operation from the input interface circuit 84 during a B-mode scan, the ultrasound diagnostic apparatus 100 transitions from a real-time display mode in which ultrasound images generated in conjunction with the transmission and reception of ultrasound are displayed in real time to a cine display mode in which multiple ultrasound images stored in the image memory 82 can be displayed in chronological order (hereinafter referred to as cine display).

[0121] In response to a freeze operation from the input interface circuit 84 during scanning in the Doppler mode, the ultrasound diagnostic device 100 transitions from a real-time display mode, in which a Doppler waveform generated in response to transmission and reception of ultrasound is displayed in real time, to a scroll display mode. Here, the scroll display mode is a mode in which a plurality of Doppler waveform images stored in the image memory 82 can be displayed by scrolling forward or backward in time series. For example, in the scroll display mode, when the operator rotates a trackball or the like, the ultrasound diagnostic device 100 reads out and displays a Doppler waveform image corresponding to the direction and amount of rotation of the trackball from among the plurality of Doppler waveform images stored in the image memory 82. The rotation of the trackball corresponds to a scroll operation for scrolling the time-series Doppler waveform images forward or backward in time series after input of a freeze operation.

[0122] The communication interface circuit 85 has substantially the same functions as the communication interface circuit 36, and therefore a description thereof will be omitted.

[0123] The processing circuitry 87 is, for example, a processor that functions as the core of the ultrasound diagnostic apparatus 100. The processing circuitry 87 has, as hardware resources, a processor such as a CPU or an MPU, and a memory such as a ROM or a RAM. The processing circuitry 87 may also be realized by an application specific integrated circuit, a field programmable gate array, another composite programmable logic device, or a simple programmable logic device.

[0124] The processing circuitry 87 has various functions such as a control function 87a, an image processing function 87b, an information management function 87c, and a judgment function 87d. The processing circuitry 87 deploys various programs stored in the storage circuitry 81 in its own memory and executes them to execute the control function 87a, the image processing function 87b, the information management function 87c, and the judgment function 87d corresponding to the programs. Note that instead of being stored in the storage circuitry 81, the programs may be configured to be directly incorporated into the circuitry of the processor. In this case, the processor realizes the above functions by reading and executing the programs incorporated in the circuitry.

[0125] The processing circuit 87 that executes the control function 87a, the information management function 87c, and the judgment function 87d corresponds to the control unit, the information management unit, and the judgment unit. Note that the control function 87a, the image processing function 87b, the information management function 87c, and the judgment function 87d are not limited to being realized by a single processing circuit. A processing circuit may be configured by combining a plurality of independent processors, and each processor may execute a program to realize the control function 87a, the image processing function 87b, the information management function 87c, and the judgment function 87d.

[0126] In addition, the functions related to the treatment procedure support processing realized by the control function 87a, the image processing function 87b, the information management function 87c, and the judgment function 87d are substantially similar to the control function 37a, the image processing function 37b, the information management function 37c, and the judgment function 37d in the first embodiment, so their description will be omitted.

[0127] [Treatment procedure support processing] Next, a therapeutic procedure support process executed by the ultrasound diagnostic device 100 according to this embodiment will be described. For concrete explanation, this embodiment will take as an example a case where the ultrasound diagnostic device 100 is used as a transesophageal ultrasound diagnostic device in performing a clip placement operation (mitral valve clipping) such as MitraClip (registered trademark) on the mitral valve as a therapeutic procedure.

[0128] Mitral valve clipping is performed, for example, in the following three steps. That is, in the first step, a catheter is moved to the mitral valve of the heart under observation using the X-ray diagnostic device 1. In the second step, a clip delivery system with a clip mounted at its tip is inserted from inside the catheter under observation using the ultrasound diagnostic device 100, and the clip is placed. At this time, for example, the clip is brought close to the mitral valve while observing two-dimensional images (two-chamber image, three-chamber image, etc.) using the ultrasound diagnostic device 100, and the angle of the clip is adjusted while observing three-dimensional images using the ultrasound diagnostic device 100. After the angle adjustment of the clip is completed, the clip is inserted from the left atrium to the left ventricle, and the clip is attached. In the third step, for the purpose of observation after placement, fluoroscopy and photography of the mitral valve are performed again using the X-ray diagnostic device 1 and the ultrasound diagnostic device 100. Hereinafter, a case where the treatment procedure support process is used in the second step will be described.

[0129] [Preset history information generation process] The preset history information generating process executed by the ultrasound diagnostic apparatus 100 will be described with reference to FIG.

[0130] As shown in FIG. 5, when the control function 87a receives a preset selection instruction (step S1), the information management function 87c records the selected preset in the preset history information management table (step S2).

[0131] Next, the information management function 87c judges whether the control function 87a has received an instruction to modify the settings by the preset (step S3). If the control function 87a has received an instruction to modify the settings by the preset (Yes in step S3), the information management function 87c records the contents of the modification instruction received by the control function 87a as modification information in the preset history information management table (step S4). On the other hand, if the control function 87a has not received an instruction to modify the settings by the preset (No in step S3), the process proceeds to step S5.

[0132] Next, the information management function 87c acquires situation information including at least one of the medical images acquired by the ultrasound diagnostic device 100, the images of the operating room acquired by the optical imaging device 40, and the audio data acquired by the audio input device 41 (step S5).

[0133] Next, the judgment function 87d judges the status of the current medical procedure based on the status information acquired by the information management function 87c (step S6).

[0134] For example, the judgment function 87d uses voice recognition processing using the acquired voice data to recognize a doctor's statement, "I will now insert the clip delivery system from inside the catheter and begin the clip placement procedure," and judges that the current status of the treatment procedure is, for example, "approaching the clip to the valve."

[0135] Furthermore, for example, the determination function 87d executes human body / object recognition processing and behavior recognition processing using the acquired images of the operating room, and recognizes that a person is holding a clip delivery system, that the person is in a posture for inserting the clip delivery system into a catheter, etc. Based on the results obtained by the human body / object recognition processing and behavior recognition processing, the determination function 87d determines that the status of the current treatment procedure is, for example, "approaching the clip to the valve."

[0136] Also, for example, the determination function 87d executes object recognition processing and semantic segmentation processing using the acquired medical image to determine that the catheter has been inserted into the left atrium. Based on the fact that the catheter has been inserted into the left atrium, the determination function 87d determines that the current treatment procedure status is, for example, "approach to the clip valve."

[0137] Furthermore, for example, the determination function 87d executes object recognition processing and semantic segmentation processing using the acquired medical image to determine the positional relationship between the clip and the mitral valve. The determination function 87d also detects a motion vector in the direction of bringing the catheter closer to the mitral valve. When the distance between the clip and the mitral valve becomes equal to or less than a certain value (for example, the absolute value of the average motion over a certain period of time is equal to or less than a threshold value) and the motion vector becomes equal to or less than a certain value, the determination function 87d determines that the current treatment procedure status has transitioned from, for example, "approach of the clip to the valve" to "adjustment of the clip angle". Here, the reason why the determination criterion is set to, for example, "when the distance between the clip and the mitral valve becomes equal to or less than a certain value and the motion vector becomes equal to or less than a certain value" is that the distance between the clip and the mitral valve does not become equal to a certain value (for example, 0) due to body movement or the like.

[0138] Next, the information management function 87c records the status of the current medical procedure determined by the determination function 87d in the preset history information management table (step S7).

[0139] By the processes in steps S1 to S7 described above, preset history information is generated in accordance with preset selection.

[0140] [Preset suggestion processing] The preset suggestion process executed by the ultrasound diagnostic device 100 will be described with reference to Fig. 6. Note that each process from steps S11 to S14 is similar to that in the first embodiment, and therefore the description thereof will be omitted.

[0141] Next, the determination function 87d refers to the preset history information management table to determine whether or not modification information corresponding to the candidate preset exists (step S15). If the determination function 87d determines that modification information corresponding to the candidate preset exists (Yes in step S15), the information management function 87c modifies the candidate preset using the modification information (step S16).

[0142] For example, assume that the candidate preset selected in step S13 is "mid-esophageal mitral valve commissure view (2-chamber view: 60-90°)" or "mid-esophageal aortic valve long axis view (3-chamber view: 100-160°)" corresponding to the preset with management number "1" in the preset information management table shown in FIG. 9. In this case, the determination function 87d refers to preset history information in the preset history information management table whose situation is similar to the situation of the candidate preset "approach to the clip valve" and determines whether or not correction information exists. If correction information exists, the information management function 87c corrects the candidate preset based on the correction information. On the other hand, if correction information does not exist, the candidate preset is not corrected.

[0143] Also, for example, assume that the candidate preset selected in step S13 is "3D image display" corresponding to the preset with management number "59" in the preset information management table shown in FIG. 9. In this case, the determination function 87d refers to preset history information in the preset history information management table whose situation is similar to the situation of the candidate preset "adjusting clip angle" and determines whether or not correction information exists. If correction information exists, the information management function 87c corrects the candidate preset based on the correction information. On the other hand, if correction information does not exist, the candidate preset is not corrected.

[0144] Also, for example, assume that the candidate preset selected in step S13 is "Suggest changing the alert condition to clip attached mode" corresponding to the preset with management number "100" in the preset information management table shown in FIG. 9. In this case, the determination function 87d refers to preset history information in the preset history information management table whose status is similar to the status of the candidate preset "clip attached" and determines whether or not correction information exists. If correction information exists, the information management function 87c corrects the candidate preset based on the correction information. On the other hand, if correction information does not exist, the candidate preset is not corrected.

[0145] On the other hand, if the determination function 87d determines that there is no modification information corresponding to the candidate preset (No in step S15), the process proceeds to step S17.

[0146] Next, the control function 87a causes the display unit 83 to present (display) the candidate preset corrected in step S16 when the correction information exists, and the candidate preset determined in step S14 when the correction information does not exist, as a proposed preset (step S17). If necessary, the control function 87a outputs the content of the proposed preset as audio data from the speaker. The control function 87a also causes the display unit 83 to present an inquiry about whether the proposed preset needs to be executed, together with the proposed preset. If there are multiple candidate presets, the process of steps S14 to S17 can be performed for each candidate preset, and multiple proposed presets can be presented on the display unit 83.

[0147] Next, the control function 87a judges whether or not the proposed preset has been selected (whether or not an instruction requiring execution of the proposed preset has been received) (step S18). When an instruction requiring execution of the proposed preset has been input from the input interface circuit 84 ("Yes" in step S18), the control function 87a executes control according to the proposed preset (step S19). For example, when the proposed preset is "3D image display", the control function 37a controls the ultrasound transmission circuit 71, the ultrasound reception circuit 73, the B-mode processing circuit 75, the Doppler processing circuit 77, the image generation circuit 79, and the display unit 35 so as to change the setting from "mid-esophageal mitral valve commissure view (2-chamber view: 60-90°)" and "mid-esophageal aortic valve long axis view (3-chamber view: 100-160°)" to "3D image display". Also, for example, when the proposed preset is "suggest changing the alert condition to the clip attached mode", the control function 37a transmits a control signal to the vital sign measuring device 43 to instruct the change of the alert condition to the clip attached mode.

[0148] On the other hand, if an instruction requiring execution of the proposed preset is not input from the input interface circuit 33 ("No" in step S18), the processes in steps S11 to S18 are repeatedly executed.

[0149] As described above, the ultrasound diagnostic apparatus 100 as the medical image diagnostic apparatus according to this embodiment can also achieve the same effects as the X-ray diagnostic apparatus 1 according to the first embodiment.

[0150] In particular, the ultrasound diagnostic device 100 according to this embodiment can determine presets related to settings of external devices that are currently or will be required by the surgeon in the treatment procedure based on the status of the current treatment procedure, and present the presets to the surgeon as suggested presets. Therefore, by selecting a suggested preset, the surgeon can easily and quickly realize settings of not only the ultrasound diagnostic device 100, but also external devices that are currently or will be required by the surgeon.

[0151] As a result, the ultrasound diagnostic apparatus 100 according to this embodiment can reduce the burden on the surgeon when realizing desired settings of the ultrasound diagnostic apparatus 100 and desired settings of external devices used simultaneously with the ultrasound diagnostic apparatus 100, thereby helping the surgeon to concentrate on his or her own procedure.

[0152] (Variation 1) In the above embodiment, the X-ray diagnostic apparatus 1 and the ultrasound diagnostic apparatus 100 as medical image diagnostic apparatuses execute the above-mentioned therapeutic procedure support process. Alternatively, the above-mentioned therapeutic procedure support process may be executed by a medical image processing apparatus such as a medical workstation. Such a medical image processing apparatus can be used in any environment as long as it is capable of communicating in real time with a medical image diagnostic apparatus such as the X-ray diagnostic apparatus 1 via a network such as an in-hospital network or a cloud network.

[0153] (Variation 2) In the above-mentioned embodiments, the case where the X-ray diagnostic apparatus 1 and the ultrasound diagnostic apparatus 100 execute the above-mentioned therapeutic procedure support process has been described as an example. However, the present invention is not limited to the X-ray diagnostic apparatus 1 and the ultrasound diagnostic apparatus 100, and can be applied to any medical image diagnostic apparatus used in a therapeutic procedure. Examples of medical image diagnostic apparatus used in a therapeutic procedure include an endoscope system, an X-ray computed tomography imaging apparatus, a magnetic resonance imaging apparatus, etc., in addition to an X-ray diagnostic apparatus and an ultrasound diagnostic apparatus.

[0154] (Variation 3) In the above-described second embodiment, the ultrasound diagnostic apparatus 100 issues a control instruction to the vital sign measuring device 43 as an external device according to the proposed preset obtained by the medical procedure support process. However, the external device is not limited to the vital sign measuring device 43, and may be a contrast agent injection device, another medical image diagnostic device, or the like.

[0155] For example, in the above-mentioned mitral valve clipping procedure, observation may be performed using the X-ray diagnostic apparatus 1 and the ultrasound diagnostic apparatus 100. In this case, for example, the X-ray diagnostic apparatus 1 issues a control instruction to the ultrasound diagnostic apparatus 100 as an external apparatus according to a proposed preset obtained by the therapeutic procedure support process (or vice versa), thereby realizing the therapeutic procedure support process in which the X-ray diagnostic apparatus 1 and the ultrasound diagnostic apparatus 100 are linked together.

[0156] According to at least one of the embodiments described above, it is possible to reduce the burden on an operator when using the preset function of a medical image diagnostic apparatus.

[0157] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
