Description

[Technical Field]

[0001] The embodiments disclosed in this specification and drawings relate to an X-ray diagnostic device. [Background technology]

[0002] Conventionally, there is known an X-ray diagnostic apparatus that irradiates an object with X-rays and obtains an X-ray projection image based on the X-rays that pass through the object. In such an X-ray diagnostic apparatus, a table-side console that allows an operator or technician to operate a C-arm or the like is configured to be hangable on, for example, a side rail of a bed.

[0003] In order to allow for flexible installation of the console, long power and signal cables were sometimes used to connect the console and the bed. However, depending on the length of the cables, they could hang down below the bed, creating problems in terms of cleanliness and clutter. [Prior art documents] [Patent documents]

[0008] Hereinafter, an X-ray diagnostic apparatus according to each embodiment will be described with reference to the drawings. In the following description, components having the same or substantially the same functions as those described above with reference to the previous drawings will be given the same reference numerals and will be described only if necessary. Even when the same parts are shown, the dimensions and proportions may be different depending on the drawing. Furthermore, for example, in order to ensure the visibility of the drawings, only the main components may be given reference numerals in the description of each drawing, and components having the same or substantially the same functions may not be given reference numerals.

[0009] In each embodiment described below, an X-ray diagnostic apparatus will be exemplified as an example of a medical image diagnostic apparatus, but the present invention is not limited thereto. The technology according to each embodiment may be applied to medical image diagnostic apparatuses other than X-ray diagnostic apparatuses. Examples of other medical image diagnostic apparatuses include an X-ray computed tomography (CT) apparatus, a magnetic resonance imaging (MRI) apparatus, an ultrasound diagnostic apparatus, a SPECT (Single Photon Emission Computed Tomography) apparatus, a PET (Positron Emission Computed Tomography) apparatus, a SPECT-CT apparatus in which a SPECT apparatus and an X-ray CT apparatus are integrated, and a PET-CT apparatus in which a PET apparatus and an X-ray CT apparatus are integrated.

[0010] (First embodiment) 1 is a diagram showing an example of the configuration of an X-ray diagnostic apparatus 100 according to an embodiment. The X-ray diagnostic apparatus 100 is an example of a medical image diagnostic apparatus that generates medical image data based on data collected from a subject P. For the sake of concreteness, the following description will be given taking as an example a case where the X-ray diagnostic apparatus 100 is a cardiovascular X-ray diagnostic apparatus.

[0011] The X-ray diagnostic apparatus 100 includes an imaging unit 3, a bed 5, a drive unit 7, an operation unit 9, an X-ray high-voltage device 11, a processing circuit 21, a memory circuit 23, a display unit 25, and an input interface 27. The processing circuit 21, the memory circuit 23, and the input interface 27 are built into, for example, the console device 10. The imaging unit 3 includes an X-ray tube 13 that irradiates X-rays onto the subject P, an X-ray detector 17 that detects X-rays, an X-ray aperture 15, and a holding device 19. The imaging unit 3 further includes a support arm. The bed 5 is provided with an operation unit 9 for operating the imaging unit 3 and the bed 5. The drive unit 7 that drives the imaging unit 3 and the bed 5 includes an imaging system movement drive unit 71 and a tabletop movement drive unit 73.

[0012] The X-ray high voltage device 11 includes electrical circuits such as a transformer and a rectifier, a high voltage generator, and an X-ray control device. The high voltage generator has the function of generating a high voltage to be applied to the X-ray tube 13 and a filament current to be supplied to the X-ray tube 13. The X-ray control device controls the output voltage according to the X-rays emitted by the X-ray tube 13. The high voltage generator may be of a transformer type or an inverter type. The X-ray high voltage device 11 may be provided in the holding device 19.

[0013] The X-ray tube 13 is a vacuum tube that generates X-rays by irradiating thermions from a cathode (filament) toward an anode (target) when a high voltage is applied from the X-ray high voltage device 11 and a filament current is supplied. X-rays are generated when thermions collide with the target. The X-ray tube 13 is, for example, a rotating anode type X-ray tube that generates X-rays by irradiating a rotating anode with thermions. Note that the X-ray tube 13 is not limited to the rotating anode type, and any type of X-ray tube can be used.

[0014] The X-ray diaphragm 15 is provided in front of the X-ray radiation window in the X-ray tube 13. The X-ray diaphragm 15 has four diaphragm blades made of metal plates such as lead. The diaphragm blades are driven by a drive device (not shown) in accordance with the region of interest input by the operator via the operation unit 9 or the input interface 27. The X-ray diaphragm 15 adjusts the region where X-rays are blocked to any size by sliding the diaphragm blades with the drive device. With the adjusted diaphragm blades, the X-ray diaphragm 15 blocks X-rays outside the opening region. In this way, the X-ray diaphragm 15 narrows down the X-rays generated by the X-ray tube 13 so that they are irradiated onto the region of interest of the subject P.

[0015] The X-ray detector 17 detects X-rays generated by the X-ray tube 13. The X-ray detector 17 is, for example, a flat panel detector (hereinafter referred to as FPD). The FPD has multiple semiconductor detection elements. There are two types of semiconductor detection elements: a direct conversion type that directly converts X-rays into electrical signals, and an indirect conversion type that converts X-rays into light using a phosphor and then converts the light into electrical signals. Either type may be used for the FPD. Electrical signals generated by the multiple semiconductor detection elements in response to incidence of X-rays are output to an analog-to-digital converter (hereinafter referred to as A / D converter), not shown. The A / D converter converts the electrical signals into digital data. The A / D converter outputs the digital data to the processing circuit 21. Note that an image intensifier may be used as the X-ray detector 17.

[0016] The holding device 19 is a C-arm that supports the X-ray tube 13 and the X-ray detector 17. The holding device 19 is rotated around the subject P lying on the bed 5 by a motor (not shown). Here, the holding device 19 is supported so as to be rotatable about three orthogonal axes, the X, Y and Z axes, and is rotated around each axis by a drive unit (not shown).

[0017] The processing circuitry 21 controls the overall operation of the X-ray diagnostic apparatus 100 in response to electrical signals of input operations output from the operation unit 9 or the input interface 27. For example, the processing circuitry 21 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).

[0018] Various processing functions executed by the processing circuitry 21 are stored in the form of computer-executable programs in the storage circuitry 23. The processing circuitry 21 is a processor that realizes the functions corresponding to each program by reading and executing the programs from the storage circuitry 23. In other words, each circuit that has read each program has the function corresponding to the read program.

[0019] Specifically, the processing circuitry 21 executes an operation control function 211, an image generation function 212, a connection detection function 213, a communication control function 214, and a power supply function 215 using a processor that executes a program loaded in memory. Here, the processing circuitry 21 that realizes the connection detection function 213 is an example of a detection control unit. Furthermore, the processing circuitry 21 that realizes the communication control function 214 is an example of a communication unit. Furthermore, the processing circuitry 21 that realizes the power supply function 215 is an example of a power supply control unit.

[0020] The operation control function 211, image generation function 212, connection detection function 213, communication control function 214, and power supply function 215 are not limited to being realized by a single processing circuit. A processing circuit may be configured by combining multiple independent processors, and the operation control function 211, image generation function 212, connection detection function 213, communication control function 214, and power supply function 215 may be realized by each processor executing a program.

[0021] In addition, the processing circuit 21 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).

[0022] The operation control function 211 controls the drive unit 7, the X-ray high voltage device 11, the X-ray diaphragm 15, the memory circuitry 23, the display unit 25, etc. based on input operations received from the operator via the operation unit 9 or the input interface 27. Specifically, the operation control function 211 reads out a control program stored in the memory circuitry 23, expands it on the memory in the processing circuitry 21, and controls each unit of the X-ray diagnostic apparatus 100 in accordance with the expanded control program. For example, the operation control function 211 includes a display control function that displays an image on the display 251 based on various image data such as X-ray projection image data generated by the image generation function 212.

[0023] The image generation function 212 generates image data based on the output from the X-ray detector 17. Specifically, the image generation function 212 generates projection data (data of an X-ray attenuation image) based on the output from the X-ray detector 17. Next, the image generation function 212 receives an input signal from the operation unit 9 or the input interface 27, and performs processes such as defective pixel correction, gain correction, and offset correction on the output signal from the X-ray detector 17 to generate an X-ray projection image. The X-ray projection image corresponds to a medical image including a fluoroscopic image or a photographed image of the subject P. The image generation function 212 performs synthesis processing, subtraction processing, and the like using the X-ray projection image. The image generation function 212 outputs the generated X-ray projection image to the memory circuitry 23.

[0024] The connection detection function 213 detects that the operation unit 9 is attached to the side rail 53 based on the output of a tactile switch 91 provided on the side rail 53 or the operation unit 9 .

[0025] The communication control function 214 controls communication between the bed 5 and the operation unit 9 by a communication unit provided together with the electrode units 63, 65. When the connection detection function 213 detects that the operation unit 9 is attached to the side rail 53, the communication control function 214 starts or allows communication between the bed 5 and the operation unit 9.

[0026] The power supply function 215 controls the power supply to the operation unit 9 via the interface 6. When the connection detection function 213 detects that the operation unit 9 is attached to the side rail 53, the power supply function 215 starts or allows the power supply to the operation unit 9 via the interface 6.

[0027] The memory circuitry 23 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 a circuit that combines a plurality of such storage devices. The memory circuitry 23 includes, for example, a storage device for primary storage and a storage device for long-term storage. Medical images sequentially stored in the primary storage device are updated, for example, periodically. The memory circuitry 23 also stores, for example, projection data (X-ray attenuation images), image data, and programs corresponding to various functions read and executed by the processing circuitry 21. The memory circuitry 23 may be a drive device that reads and writes various information from / to portable storage media 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 an SSD. The memory circuitry 23 may also be located in an external storage device connected via a network. Furthermore, when the memory circuitry 23 includes multiple storage devices, some of the storage devices may be connected via a network.

[0028] The display unit 25 is composed of a display 251 that displays medical images, etc., an internal circuit that supplies display signals to the display 251, and peripheral circuits such as connectors and cables that connect the display 251 to the internal circuit. The internal circuit generates display data by superimposing additional information such as subject information and projection data generation conditions on 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 undergone these conversions on the display 251 as a medical image. In addition, the display unit 25 displays a GUI (Graphical User Interface) and the like for receiving various operations from the operator.

[0029] As the display 251, for example, a liquid crystal display (LCD), a cathode ray tube (CRT) display, an organic electroluminescence display (OLED), a plasma display, or any other display can be appropriately used. The display 251 may be a desktop type, or may be configured as a tablet terminal or the like capable of wireless communication with the processing circuit 21. The display 251 may also be one or more projectors.

[0030] The input interface 27 accepts various input operations from the operator, converts the accepted input operations into electrical signals, and outputs the electrical signals to the processing circuit 21. For example, the input interface 27 accepts from the operator operations for operating at least one of the imaging unit 3 and the bed 5, X-ray conditions related to the generation of X-rays, conditions related to image processing executed by the image generation function 212, etc. As the input interface 27, for example, a mouse, keyboard, trackball, switch, button, joystick, foot switch, touchpad, touch panel display, etc. can be used as appropriate. The input interface 27 is mounted, for example, on the console device 10 installed in an operation room different from the examination room.

[0031] In this embodiment, the input interface 27 is not limited to one having physical operation parts such as a mouse, keyboard, trackball, switch, button, joystick, touchpad, and touch panel display. For example, an example of the input interface 27 also 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 21. The input interface 27 may be configured as a tablet terminal or the like that can wirelessly communicate with the processing circuit 21.

[0032] 2 is a diagram showing an example of the configuration of a power supply unit and a communication unit in the bed 5 according to the first embodiment. As shown in FIG. 2, the bed 5 is provided with a support unit 51 and side rails 53.

[0033] The support portion 51 supports the side rail 53. The support portion 51 is, for example, a hollow member, and the connection line 61 is disposed inside.

[0034] The side rails 53 are provided on the sides of the bed 5 and extend along the longitudinal direction of the bed 5 (the y direction in FIG. 2). The side rails 53 detachably hold the operation unit 9. Here, the side rails 53 are an example of a holding member. The side rails 53 may also be expressed as a rail-shaped holding member.

[0035] The bed 5 is also provided with an interface 6 that functions as a power supply unit and a communication unit. As an example, the interface 6 is a power supply interface that outputs power to supply power to the operation unit 9. As another example, the interface 6 is a communication interface for communication between the operation unit 9 and the processing circuit 21. The interface 6 is electrically connected to an electrode unit 63 provided on the side rail 53 by a connection line 61. The connection line 61 is an example of a power supply unit.

[0036] FIG. 3 is a diagram showing an example of the arrangement of the electrode portions 63 on the side rail 53 according to the first embodiment.

[0037] As shown in FIG. 3 , the electrode unit 63 is provided, for example, below the side rail 53 (on the −z side in FIG. 3 ). The electrode unit 63 is an example of a power supply unit provided on the side rail 53 for supplying power to the operation unit 9. The electrode unit 63 is electrically connected to the operation unit 9 by contacting the operation unit 9 held by the side rail 53. The electrode unit 63 has, for example, a contact for supplying power and a contact for transmitting and receiving signals. In other words, the electrode unit 63 is also an example of a communication unit provided on the side rail 53 for communicating with the operation unit 9.

[0038] 3, an electrode cover 55 is provided on the side rail 53. The electrode cover 55 is detachably held by the side rail 53. The electrode cover 55 is formed to cover the electrode section 63 while being held by the side rail 53. Here, the electrode cover 55 is an example of a cover member.

[0039] By providing electrode cover 55 near electrode unit 63 in this manner, the electrodes for connecting to operation unit 9 serving as a table-side console can be covered to prevent the electrodes from being exposed when they are not in use. This prevents conductors such as instruments or the human body from coming into contact with electrode unit 63 and causing a short circuit.

[0040] In the present embodiment, the electrode portion 63 is provided, for example, on the lower side of the side rail 53 (the -z side in FIG. 3), but this is not limiting. The electrode portion 63 may be provided on another surface of the side rail 53. For example, by providing the electrode portion 63 on the rear side (+x side) of the side rail 53, a configuration can be achieved in which conductors such as instruments and the human body are less likely to come into contact with the electrode portion 63.

[0041] In this embodiment, the side rails 53 are provided on the sides of the bed 5 and extend along the longitudinal direction of the bed 5 (the y direction in FIG. 2), but are not limited to this. The technology according to this embodiment can be applied to each of the rails on the left side (-x side), right side (+x side), and foot side (+y side) of a patient placed on the top board of the bed 5. Each of these rails is also an example of a holding member.

[0042] Fig. 4 is a diagram showing an example of the operation unit 9 as a table-side console according to the first embodiment. Fig. 5 is a diagram showing an example of attachment of the operation unit 9 as a table-side console to a side rail 53 in the bed according to the first embodiment.

[0043] The operation unit 9 receives various input operations from an operator, converts the received input operations into electrical signals, and outputs them to the processing circuit 21 via the interface 6. The operation unit 9 also displays a GUI or the like for receiving various operations from the operator. The operation unit 9 is configured, for example, with a tablet terminal or the like that can communicate with the processing circuit 21 wired or wirelessly.

[0044] As with the input interface 27, the operation unit 9 can use various input devices as appropriate. As with the display unit 25, the operation unit 9 can use various display devices as appropriate.

[0045] 4 and 5, the operating unit 9 is detachably held by the side rail 53. As an example, the operating unit 9 has an upper attachment portion 90a and a lower attachment portion 90b. The operating unit 9 can be attached to the side rail 53 by fitting the lower attachment portion 90b into the lower side (-z side) of the side rail 53 with the upper attachment portion 90a hooked onto the upper side (+z side) of the side rail 53.

[0046] At least one of the upper attachment portion 90a and the lower attachment portion 90b may be configured to be rotatable around the y-axis with respect to the main body (-x side) of the operation unit 9. In this case, the operation unit 9 can be attached to the side rail 53 by rotating at least one of the upper attachment portion 90a and the lower attachment portion 90b with the back side (+x side) of the main body in contact with the side rail 53 to sandwich the side rail 53.

[0047] According to these configurations, the operating unit 9 can be attached to the side rail 53 at any position along the side rail 53, i.e., in the y direction. Furthermore, the attachment position of the operating unit 9 along the side rail 53 can be changed at any position.

[0048] 3 and 5, by mounting the operation unit 9 at a position where the electrode unit 63 is provided among the mount positions that can be changed along the side rail 53, the operation unit 9 and the electrode unit 63 can be brought into contact and electrically connected. This allows electrical connection between the interface 6 and the operation unit 9, thereby realizing power supply to the operation unit 9 mounted at a predetermined position on the side rail 53. Similarly, communication is realized between the operation unit 9 mounted at a predetermined position on the side rail 53 and the processing circuit 21.

[0049] The operating unit 9 may be equipped with a battery. In this case, the operating unit 9 can be used regardless of the position at which it is attached along the side rail 53.

[0050] As shown in FIGS. 4 and 5 , a tactile switch 91 that determines whether the operation unit 9 is attached to the side rail 53 is provided on the back of the main body of the operation unit 9. Here, the tactile switch 91 is an example of a detection unit. The tactile switch 91 is configured to be turned on when the back of the main body of the operation unit 9 comes into contact with the side surface of the side rail 53. When the tactile switch 91 is turned on, the connection detection function 213 detects that the operation unit 9 is attached to the side rail 53. In other words, the tactile switch 91 detects that the operation unit 9 is attached to the side rail 53.

[0051] When the tactile switch 91 is on, the communication control function 214 starts or allows communication with the operation unit 9. In addition, the power supply function 215 starts or allows power supply to the operation unit 9 via the interface 6. On the other hand, when the tactile switch 91 is off, it can be determined that the operation unit 9 is away from the side rail 53, and therefore, for safety reasons, power supply and signal transmission / reception are not performed.

[0052] In this embodiment, the operation unit 9 is provided with the tactile switch 91, but this is not limiting. The tactile switch 91 may be provided on the side rail 53 side, or may be provided on both the operation unit 9 and the side rail 53.

[0053] Furthermore, instead of the tactile switch 91, a contact sensor using a strain sensor or the like may be used to realize a detection unit that detects that the operation unit 9 is attached to the side rail 53.

[0054] The configuration for detecting that the operation unit 9 such as the tactile switch 91 is attached to the side rail 53 is not essential, and may not be provided in the X-ray diagnostic apparatus 100.

[0055] As described above, in the X-ray diagnostic apparatus 100 according to the embodiment, the electrode section 63 for connection to the operation section 9 is provided inside the side rail 53 of the bed 5 .

[0056] According to this configuration, even when a table-side console for operating a C-arm or the like by an operator or technician is hung on the side rail 53 of the bed 5, the cable of the console can be prevented from hanging down below the bed 5. Therefore, the X-ray diagnostic apparatus 100 according to the embodiment can improve cleanliness and reduce the complexity of cable management. Furthermore, the console can be freely installed without using long cables.

[0057] (Second embodiment) Next, an X-ray diagnostic apparatus 100 according to a second embodiment will be described. Here, differences from the first embodiment will be mainly described. Fig. 6 is a diagram showing an example of the arrangement of electrode parts 65 on a side rail 53 according to the second embodiment.

[0058] In the first embodiment, the interface 6 and the operation unit 9 are electrically connected by the operation unit 9 contacting the electrode unit 63 provided on the side rail 53, but this is not limiting. As shown in FIG. 6, the side rail 53 may be provided with a non-contact electrode unit 65 capable of supplying power and transmitting and receiving signals.

[0059] Note that the transmission and reception of signals using the non-contact electrode unit 65 can be performed using any wireless communication standard such as Bluetooth (registered trademark) or infrared. In the bed 5, the antenna circuit for wireless communication may be provided, for example, near the side rail 53 or the support pillar of the bed 5. Here, the antenna circuit for wireless communication is an example of a communication unit for wireless communication with the operation unit 9.

[0060] According to the X-ray diagnostic apparatus 100 of this embodiment, even if the operation unit 9 is attached near the position where the electrode unit 65 is provided among the attachment positions that can be changed along the side rail 53, it is possible to electrically connect between the operation unit 9 and the electrode unit 63.

[0061] Furthermore, in the X-ray diagnostic apparatus 100 according to this embodiment, a non-contact electrode unit 65 is used, and therefore the contact points of the electrode unit 65 with the operation unit 9 are not exposed to the outside of the side rails 53. This prevents poor contact due to the adhesion of dirt to the contact points. It also prevents short circuits caused by contact with the contact points of the electrode unit 65 with a conductor such as a human body or an instrument. Furthermore, since the electrode cover 55 as a short-circuit prevention measure is not required, it is not necessary to attach and detach the electrode cover 55 every time the operation unit 9 is moved, reducing the effort required by the operator. Furthermore, since the electrode cover 55 is not required, the number of parts can be reduced, thereby achieving cost reduction.

[0062] Furthermore, in the X-ray diagnostic apparatus 100 according to this embodiment, when a battery is installed in the operating unit 9, operations and processes involving communication can be performed regardless of the position at which the battery is installed along the side rail 53, which can be changed.

[0063] (Third embodiment) Next, an X-ray diagnostic apparatus 100 according to a third embodiment will be described. Here, differences from the first embodiment will be mainly described. Fig. 7 is a diagram showing an example of the configuration of a power supply unit and a communication unit in a bed 5 according to the third embodiment.

[0064] In the first embodiment, the interface 6 and the operation unit 9 are electrically connected by the operation unit 9 contacting the electrode unit 63 provided at one predetermined position on the side rail 53, but this is not limiting. The side rail 53 may be provided with a plurality of electrode units 63, as shown in FIG. 7 .

[0065] 7, in the X-ray diagnostic apparatus 100 according to this embodiment, a plurality of electrode units 63 are arranged at a plurality of positions along the side rail 53. This allows the operation unit 9 to be electrically connected to the interface 6 at each of a plurality of positions along the side rail 53 among the attachment positions that can be changed along the side rail 53.

[0066] In this way, the operating unit 9 can be electrically connected to the interface 6 at each of the positions of the multiple electrode units 63 along the side rail 53, among the mounting positions that can be changed along the side rail 53, so the installation position of the operating unit 9 can be freely changed.

[0067] In the X-ray diagnostic apparatus 100 according to this embodiment, the number of electrode units 63 may be two, or may be four or more.

[0068] In the X-ray diagnostic apparatus 100 according to this embodiment, the electrode section 63 is not limited to a contact type, and a non-contact type electrode section 65 may also be used.

[0069] (Fourth embodiment) Next, an X-ray diagnostic apparatus 100 according to a fourth embodiment will be described. Here, differences from the first embodiment will be mainly described. Fig. 8 is a diagram showing an example of the configuration of a power supply unit in a bed 5 according to the fourth embodiment. Fig. 9 is a diagram showing an example of the arrangement of electrode units 63a, 63b in a side rail 53 according to the fourth embodiment.

[0070] In the first embodiment, the case where the interface 6 and the operation unit 9 are electrically connected by the operation unit 9 coming into contact with an electrode unit 63 provided at a predetermined position on the side rail 53 has been exemplified, but this is not limiting. As shown in FIG. 8, the side rail 53 may be provided with electrode units 63a and 63b along the side rail 53. In the following description, the electrode units 63a and 63b may be collectively referred to as the electrode unit 63.

[0071] In the X-ray diagnostic apparatus 100 according to this embodiment, electrode sections 63a and 63b are arranged along the side rails 53, as shown in FIG.

[0072] The electrode portions 63a and 63b are two electrode portions with different polarities. In the examples shown in Figures 8 and 9, the electrode portions 63a and 63b are positive and negative electrode portions, respectively. The positive electrode portions 63a and 63b are electrically connected to the positive and negative interfaces 6a and 6b via the positive and negative connection lines 61a and 61b, respectively.

[0073] Therefore, the operation unit 9 held by the side rails 53 can be electrically connected to the +side and -side interfaces 6a and 6b by contacting the two electrode units 63a and 63b of different polarities.

[0074] According to this configuration, the operating unit 9 held by the side rail 53 can be electrically connected to the interface 6 at each of the mounting positions that can be changed along the side rail 53, and the installation position of the operating unit 9 can be freely changed.

[0075] 9 illustrates an example in which the two electrode portions 63a, 63b with different polarities are provided on the same surface of the side rail 53 (the lower (-z) surface in FIG. 9), but this is not limiting. The two electrode portions 63a, 63b with different polarities may be provided on different surfaces of the side rail 53. As an example, one of the two electrode portions 63a, 63b with different polarities is provided on the upper side (the +z side in FIG. 9) of the side rail 53, and the other is provided on the lower side (the -z side in FIG. 9) of the side rail 53. As another example, one of the two electrode portions 63a, 63b with different polarities is provided on the upper side (the +z side in FIG. 9) or lower side (the -z side in FIG. 9) of the side rail 53, and the other is provided on the outer side (the -x side in FIG. 9) or the inner side (the +x side in FIG. 9) of the side rail 53.

[0076] In this way, by arranging the two electrode parts 63a and 63b with different polarities apart, it is possible to prevent short circuits.

[0077] In the X-ray diagnostic apparatus 100 according to this embodiment, communication between the operation unit 9 and the interface 6 may be performed via the electrode unit 63 or by wireless communication.

[0078] (Fifth embodiment) Next, an X-ray diagnostic apparatus 100 according to a fifth embodiment will be described. Here, differences from the fourth embodiment will be mainly described. Fig. 10 is a diagram showing an example of the configuration of a power supply unit in a bed 5 according to the fifth embodiment.

[0079] In the fourth embodiment, the interface 6 and the operation unit 9 are electrically connected by the operation unit 9 contacting the electrode unit 63 provided along the side rail 53 at any position, but this is not limiting. As shown in FIG. 10 , a non-contact electrode unit 65 may be provided along the side rail 53.

[0080] According to this configuration, the same effects as those of the X-ray diagnostic apparatus 100 according to the second embodiment and the X-ray diagnostic apparatus 100 according to the fourth embodiment can be obtained.

[0081] (Sixth embodiment) Next, an X-ray diagnostic apparatus 100 according to a sixth embodiment will be described, focusing mainly on the differences from the first embodiment.

[0082] In the first embodiment, the case where power supply and communication between the interface 6 and the operation unit 9 are realized by the operation unit 9 contacting the electrode unit 63 provided along the side rail 53 at any position has been exemplified, but this is not limiting. Power may be supplied from the interface 6 to the operation unit 9 by contacting the operation unit 9 with the electrode unit 63, and wireless communication may be performed between the interface 6 and the operation unit 9.

[0083] This configuration reduces the amount of routing of the connection line 61 on the side rail 53. Furthermore, if the operation unit 9 is equipped with a battery, power can be supplied by contacting the electrode unit 63 before and after use, and the operation unit 9 can be attached to the side rail 53 and used regardless of the position of the electrode unit 63. The technology according to this embodiment is applicable to the X-ray diagnostic apparatus 100 according to each of the above-mentioned embodiments.

[0084] (Seventh embodiment) Next, an X-ray diagnostic apparatus 100 according to the seventh embodiment will be described. Here, differences from the first embodiment will be mainly described. Fig. 11 is a diagram showing an example of the configuration of a power supply unit in a bed according to the seventh embodiment.

[0085] A movable electrode unit 63 is provided on the side rail 53 of the bed 5 according to this embodiment. Instead of the electrode unit 63, a movable non-contact electrode unit 65 may be provided on the side rail 53. The movable electrode unit 63 is configured to be movable along the side rail 53.

[0086] The connection line 61 between the movable electrode part 63 and the interface 6 is stored using a support guide member 67 as shown in FIG.

[0087] The support guide member 67 has a space within the main body through which cables and the like are passed. The support guide member 67 has a moving end on which the electrode unit 63 is provided or which is connected to a member on which the electrode unit 63 is provided, and a fixed end on the interface 6 side, and supports and guides cables and the like passed through the main body between the moving end and the fixed end. As the support guide member 67, for example, a Cableveyor (registered trademark) or a flexible tube can be used as appropriate.

[0088] The support and guide member 67 has a structure with few irregularities or gaps on the surface, which improves the cleanliness and ease of cleaning of the support and guide member 67.

[0089] The support guide member 67 can store not only the cable of the operation unit 9 of the X-ray diagnostic apparatus 100 but also the cables of units of other modalities. This makes it possible to prevent cables of other modalities that may be used together with the X-ray diagnostic apparatus 100 from sagging.

[0090] As described above, in the X-ray diagnostic apparatus 100 according to this embodiment, the electrode section 63 is configured to be movable along the side rails 53 , and the connection line 61 is held by the support guide member 67 .

[0091] Even with this configuration, the operation unit 9 held by the side rails 53 can be electrically connected to the electrode unit 63 at each of the positions of the electrode unit 63 moved along the side rails 53 among the mounting positions of the operation unit 9 that can be changed along the side rails 53. Furthermore, since the connection line 61 is held by the support guide member 67, the cable can be prevented from hanging down below the bed.

[0092] (Eighth embodiment) Next, an X-ray diagnostic apparatus 100 according to an eighth embodiment will be described. Here, differences from the first embodiment will be mainly described. Fig. 12 is a diagram showing an example of the configuration of a power supply unit in a bed 5 according to the eighth embodiment.

[0093] The operation unit 9 serving as a table-side console according to this embodiment includes an operation unit 9a serving as a main console and at least one operation unit 9b, 9c, or 9d serving as a sub-console, as shown in Fig. 12. In the following description, the operation units 9a, 9b, 9c, and 9d may be collectively referred to as the operation unit 9.

[0094] The operation unit 9a serving as the main console is assumed to be the same as the operation unit 9 according to the first embodiment. In this case, the operation units 9b, 9c, and 9d serving as sub-consoles are electrically connected to the operation unit 9a serving as the main console held by the side rails 53 via connection lines 62a, 62b, and 62c, which are realized using cables, as shown in Fig. 12. In this case, the connection line 62d is an unnecessary cable, which is shown as an example for the sake of later explanation.

[0095] 12, the operation unit 9d as a sub-console may be electrically connected to the operation unit 9c as a sub-console held by the side rail 53 via a connection line 62d realized using a cable. In other words, the operation units 9b, 9c, and 9d as sub-consoles may each be connected to the main console via another sub-console.

[0096] In this way, the operation unit 9 may be configured with multiple consoles. Furthermore, the operation unit 9a as the main console may be responsible for communication with the interface 6, and may also be responsible for relaying signals from the operation units 9b, 9c, and 9d as sub-consoles.

[0097] As in the above-described embodiments, power may be supplied to the operation units 9b, 9c, and 9d serving as sub-consoles from the electrodes 63 and 65 provided on the side rail 53. Of course, power may also be supplied to the operation units 9b, 9c, and 9d serving as sub-consoles via the operation unit 9a serving as the main console.

[0098] In addition, each of the operation units 9b, 9c, and 9d serving as sub-consoles may communicate directly with the interface 6 via wireless communication without going through the operation unit 9a serving as the main console, or may communicate directly with the interface 6 via electrode units 63 and 65 provided on the side rail 53.

[0099] Furthermore, communication between the operation unit 9a as the main console and each of the operation units 9b, 9c, and 9d as sub-consoles can be performed via wireless communication. In this case, the connection lines 62a, 62b, 62c, and 62d realized using cables are not necessary. Note that sub-consoles configured to communicate with the main console via the connection lines 62a, 62b, 62c, and 62d realized using cables and sub-consoles configured to communicate with the operation unit 9a as the main console via wireless communication may be mixed.

[0100] The technology according to this embodiment is applicable to the X-ray diagnostic apparatus 100 according to each of the above-described embodiments.

[0101] (Ninth embodiment) Next, an X-ray diagnostic apparatus 100 according to the ninth embodiment will be described. Here, differences from the third embodiment will be mainly described. Fig. 13 is a diagram showing an example of attachment of an operation unit 9 as a table-side console to a side rail 53 in a bed 5 according to the ninth embodiment.

[0102] As shown in FIG. 13, the operation unit 9 serving as a table-side console according to this embodiment includes an operation unit 9a serving as a main console and at least one operation unit 9b, 9c serving as a sub-console.

[0103] As shown in Fig. 13, each operation unit 9 serving as a table-side console according to this embodiment has a cable provided with a connector 93 of the same type at its tip that can be connected to each of the plurality of electrode units 63, 65, and a connecting member 69 that can be connected to other cables. In the example shown in Fig. 13, the connector 93a provided at the tip of the cable of operation unit 9a, the connector 93b provided at the tip of the cable of operation unit 9b, and the connector 93c provided at the tip of the cable of operation unit 9c are all connectors 93 of the same type.

[0104] Furthermore, side rail 53 according to this embodiment is provided with cable connection ports that allow connectors 93 to be connected to the electrodes 63, 65. In other words, side rail 53 according to this embodiment is provided with multiple cable connection ports of the same type. With this configuration, each operating unit 9 can be connected to any cable connection port.

[0105] Furthermore, connecting members 69 are provided at regular intervals on the cables of each operation unit 9. As the connecting members 69, for example, a magnetic substance, a hook-and-loop fastener, an adhesive tape, or the like can be appropriately used.

[0106] By providing a connecting member to the cables in this manner, multiple cables can be bundled together even when each operating unit 9 is connected to the side rail 53 via a cable. Therefore, according to the technology of this embodiment, it is possible to prevent the cables from hanging down below the bed 5.

[0107] According to at least one of the embodiments described above, it is possible to reduce the complexity of cable routing.
