[Figure 3] FIG. 3 is a flowchart showing an example of illumination control processing executed by the X-ray diagnostic apparatus according to this embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, an X-ray diagnostic apparatus according to an embodiment will be described with reference to the drawings. In the following embodiments, parts with the same reference numerals perform similar operations, and redundant description will be omitted as appropriate.

[0009] 1 is a block diagram showing an example of an X-ray diagnostic apparatus 1 according to this embodiment. The X-ray diagnostic apparatus 1 is, for example, a general X-ray imaging apparatus. As shown in FIG. 1, the X-ray diagnostic apparatus 1 includes an imaging device 10 and a console device 20. The imaging device 10 includes an X-ray irradiation device 11, an X-ray high-voltage device 12, an X-ray detector 13, a drive unit 14, and a tabletop 15.

[0010] The console device 20 has an input interface 21, a display 22, a memory circuitry 23, and a processing circuitry 24. The X-ray diagnostic device 1 is not limited to a general X-ray imaging device, but may also be an X-ray angiography device or an X-ray TV device.

[0011] 1, the width direction of the top plate 15 is the X-axis direction, the longitudinal direction of the top plate 15 is the Y-axis direction, and the direction perpendicular to the top plate 15 is the Z-axis direction. The XY plane corresponds to the detection surface of the X-ray detector 13.

[0012] The X-ray irradiation device 11 is a device that irradiates X-rays onto the subject P. The X-ray irradiation device 11 includes an X-ray tube 111, an X-ray aperture 112, and an irradiation field lamp 113.

[0013] The X-ray tube 111 and the X-ray aperture 112 irradiate X-rays. The X-ray tube 111 and the X-ray aperture 112 are an example of an X-ray irradiation unit. The X-ray tube 111 is a vacuum tube that generates X-rays by irradiating thermoelectrons from a cathode (filament) toward an anode (target) when a high voltage is applied from the X-ray high voltage device 12 and a filament current is supplied. The X-rays are generated when the thermoelectrons collide with the target.

[0014] The X-ray aperture 112 is disposed in front of the X-ray radiation window in the X-ray tube 111. The X-ray aperture 112 has a plurality of X-ray aperture blades formed of metal plates such as lead, and an X-ray aperture driving device that drives the X-ray aperture blades by operations input by an operator via the input interface 21.

[0015] The X-ray aperture 112 adjusts the region where X-rays are blocked by sliding multiple X-ray aperture blades with an X-ray aperture drive device. With the adjusted X-ray aperture blades, the X-ray aperture 112 blocks X-rays outside the opening region. In this way, the X-ray aperture 112 narrows down the X-rays generated by the X-ray tube 111 so that they are irradiated onto the region of interest of the subject P.

[0016] The irradiation field lamp 113 irradiates visible light. The irradiation field lamp 113 is an example of a visible light irradiating unit. For example, the irradiation field lamp 113 irradiates a region of interest of the subject P with visible light. The irradiation field lamp 113 includes a light source 114, a mirror 115, and a visible light diaphragm 116.

[0017] The light source 114 generates visible light. The light source 114 is, for example, an LED (Light Emitting Diode). The light source 114 may be capable of changing the color of the visible light it generates. For example, the light source 114 can be switched between white, warm color, and red. The color of the light source 114 is not limited to these colors, and it may be capable of being changed to another color.

[0018] The mirror 115 reflects the visible light generated by the light source 114 toward the visible light diaphragm 116 .

[0019] The visible light diaphragm 116 is disposed in front of the light source 114. The visible light diaphragm 116 has a plurality of visible light diaphragm blades that block visible light, and a visible light diaphragm driving device that drives the visible light diaphragm blades in response to operations input by an operator via the input interface 21.

[0020] The visible light diaphragm 116 adjusts the area where visible light is blocked by sliding multiple visible light diaphragm blades using a visible light diaphragm drive device. For example, with the adjusted visible light diaphragm blades, the visible light diaphragm 116 blocks visible light outside the opening area. In this way, the visible light diaphragm 116 narrows the visible light generated by the light source 114 so that it is irradiated onto the region of interest of the subject P. In other words, the visible light diaphragm 116 narrows the visible light so that it is irradiated onto the area to be irradiated with X-rays.

[0021] Further, the irradiation field lamp 113 irradiates visible light according to the visible light irradiation mode under the control of the console device 20. The visible light irradiation modes include an irradiation field lamp mode, an illumination mode, and an X-ray visible mode. The irradiation field lamp mode is a mode in which visible light is irradiated onto a first irradiation area to be irradiated with X-rays by the X-ray tube 111 and the X-ray aperture 112. The illumination mode is a mode in which visible light is irradiated regardless of the first irradiation area. In other words, the illumination mode is a mode in which the irradiation field lamp 113 is used as illumination. The X-ray visible mode is a mode in which visible light is irradiated onto a second irradiation area to be irradiated with X-rays by the X-ray tube 111 and the X-ray aperture 112. The irradiation field lamp mode is an example of the first mode. The illumination mode is an example of the second mode. The X-ray visible mode is an example of the third mode.

[0022] The irradiation field lamp 113 also emits visible light so that the operator can distinguish between the illumination mode, irradiation field lamp mode, and X-ray visible mode. For example, the irradiation field lamp 113 emits visible light of a different color for each visible light irradiation mode, flashes for a different period of time, or changes the intensity of the visible light. The irradiation field lamp 113 may also emit visible light in other ways.

[0023] The X-ray high voltage device 12 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 111 and a filament current to be supplied to the X-ray tube 111. The X-ray control device controls the output voltage according to the X-rays irradiated by the X-ray tube 111. The high voltage generator may be of a transformer type or an inverter type.

[0024] The X-ray detector 13 is configured with a flat panel detector (FPD) having a plurality of X-ray detection elements arranged two-dimensionally, and detects X-rays that have passed through the subject P and are irradiated onto the X-ray detector 13. The X-ray detector 13 then outputs X-ray projection data based on the detected X-rays. This projection data is provided to the console device 20. The X-ray detector 13 may also include an image intensifier, a TV camera, etc.

[0025] The driving unit 14 moves the X-ray irradiator 11 and the X-ray detector 13 .

[0026] The top board 15 is a board on which the subject P is placed.

[0027] The input interface 21 is composed of common pointing devices such as a joystick, trackball, trackball mouse, keyboard, touch panel, and numeric keypad, as well as a hand switch for indicating the timing of X-ray exposure, and outputs an operation signal corresponding to the operator's operation to the processing circuit 24.

[0028] The display 22 is configured by a general display output device such as a liquid crystal display or an OLED (Organic Light Emitting Diode) display, and displays various information under the control of the processing circuit 24.

[0029] The storage circuit 23 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, a hard disk, an optical disk, or the like.

[0030] The memory circuitry 23 also stores dedicated programs for implementing an operation control function 241, a mode setting function 242, an illumination detection function 243, an irradiation field lamp control function 244, and a setting change function 245, which will be described later.

[0031] The processing circuitry 24 controls the overall operation of the X-ray diagnostic apparatus 1. The processing circuitry 24 has, for example, an operation control function 241, a mode setting function 242, an illumination detection function 243, an irradiation field lamp control function 244, and a setting change function 245.

[0032] Here, for example, each of the processing functions of the processing circuitry 24, namely, the operation control function 241, the mode setting function 242, the illumination detection function 243, the irradiation field lamp control function 244, and the setting change function 245, is stored in the storage circuitry 23 in the form of a computer-executable program. The processing circuitry 24 is a processor. For example, the processing circuitry 24 realizes the function corresponding to each program by reading the program from the storage circuitry 23 and executing it. In other words, the processing circuitry 24 in a state in which each program has been read has each function shown in the processing circuitry 24 of FIG. 1. Note that, although FIG. 1 illustrates the processing functions performed by the operation control function 241, the mode setting function 242, the illumination detection function 243, the irradiation field lamp control function 244, and the setting change function 245 being realized by a single processor, the processing circuitry 24 may be configured by combining multiple independent processors, and each processor may realize the function by executing a program. Furthermore, although FIG. 1 illustrates a single memory circuit 23 storing a program corresponding to each processing function, multiple memory circuits may be distributed and arranged, and the processing circuit 24 may read out the corresponding program from each memory circuit.

[0033] The term "processor" used in the above description refers to circuits such as a CPU (Central Processing Unit), a GPU (Graphical Processing Unit), an Application Specific Integrated Circuit (ASIC), a programmable logic device (e.g., a Simple Programmable Logic Device (SPLD), a Complex Programmable Logic Device (CPLD), and a Field Programmable Gate Array (FPGA)). The processor realizes its functions by reading and executing a program stored in the memory circuit 23. Note that instead of storing a program in the memory circuit 23, the processor may be configured so that the program is directly embedded in its circuitry. In this case, the processor realizes its functions by reading and executing the program embedded in its circuitry.

[0034] The operation control function 241 accepts various operations. For example, the operation control function 241 accepts an operation to change the visible light irradiation mode of the irradiation field lamp 113 via an illumination switch, an irradiation field lamp switch, and an X-ray visibility switch. The illumination mode switch is a switch that sets the visible light irradiation mode of the irradiation field lamp 113 to the illumination mode. The irradiation field lamp mode switch is a switch that sets the visible light irradiation mode of the irradiation field lamp 113 to the irradiation field lamp mode. The X-ray visibility mode switch is a switch that sets the visible light irradiation mode of the irradiation field lamp 113 to the X-ray visibility mode.

[0035] The illumination mode switch, irradiation field lamp mode switch, and X-ray visible mode switch may be switches provided on the input interface 21, may be switches provided on the tabletop 15, or may be switches displayed on the display 22. Furthermore, the operation control function 241 may accept an operation to change the visible light irradiation mode from another interface, not limited to the illumination mode switch, irradiation field lamp mode switch, and X-ray visible mode switch.

[0036] Furthermore, the operation control function 241 accepts an operation to cause the X-ray tube 111 and the X-ray aperture 112 to irradiate X-rays via an X-ray irradiation switch. The X-ray irradiation switch may be a switch provided on the input interface 21, a switch provided on the tabletop 15, or a switch displayed on the display 22. Furthermore, the operation control function 241 may accept an operation to irradiate X-rays from another interface, not limited to the X-ray irradiation switch.

[0037] Here, it is not preferable to irradiate X-rays without checking the first irradiation region where the subject P is to be irradiated with X-rays in the irradiation field lamp mode. Therefore, the operation control function 241 may limit the acceptance of an operation to irradiate X-rays. That is, the operation control function 241 may not accept an operation to irradiate X-rays in the illumination mode. In other words, the operation control function 241 may accept an operation to irradiate X-rays in the irradiation field lamp mode.

[0038] Furthermore, in the illumination mode, the operation control function 241 accepts an operation to designate an area onto which visible light is irradiated by the irradiation field lamp 113. The operation control function 241 is an example of an operation unit.

[0039] The mode setting function 242 controls the mode setting of the visible light irradiation mode of the irradiation field lamp 113. That is, the mode setting function 242 sets to the irradiation field lamp mode in which visible light is irradiated onto the first irradiation area to be irradiated with X-rays by the X-ray tube 111 and the X-ray aperture 112, or to the illumination mode in which visible light is irradiated regardless of the first irradiation area. The mode setting function 242 is an example of a setting unit. In addition, the mode setting function 242 sets to the irradiation field lamp mode, the illumination mode, or the X-ray visible mode in which visible light is irradiated onto the second irradiation area to which X-rays are irradiated by the X-ray tube 111 and the X-ray aperture 112.

[0040] The mode setting function 242 sets the illumination mode when the illumination mode switch is turned on, and sets the mode according to the irradiation field lamp mode switch when the illumination mode switch is turned off.

[0041] The mode setting function 242 sets the irradiation field lamp mode when the irradiation field lamp mode switch is turned ON. Also, the mode setting function 242 sets a mode other than the irradiation field lamp mode when the irradiation field lamp mode switch is turned OFF. Alternatively, the mode setting function 242 switches to a visible light irradiation mode other than the irradiation field lamp mode when the irradiation time of visible light irradiation in the irradiation field lamp mode has exceeded a set time. The set time is, for example, 30 seconds, but may be another period.

[0042] The mode setting function 242 sets the mode to the X-ray visible mode when the X-ray visible mode switch is turned ON. Also, when the X-ray visible mode switch is turned OFF, the mode setting function 242 sets the mode to one in which X-rays are irradiated but visible light is not irradiated.

[0043] The lighting detection function 243 detects whether a lighting device in a room where the image capturing device 10 is installed is on. The lighting detection function 243 is an example of a detection unit. More specifically, the lighting detection function 243 determines whether a lighting device is on. For example, the lighting detection function 243 determines whether a lighting device in a room is on based on an output from an illuminance sensor installed in the room. Alternatively, the lighting detection function 243 may detect whether a lighting device is on by receiving an on-state signal from the lighting device installed in the room. Note that the lighting detection function 243 may detect the illuminance of the light emitted by the lighting device, not limited to whether the lighting device is on.

[0044] The irradiation field lamp control function 244 controls the irradiation field lamp 113. More specifically, the irradiation field lamp control function 244 causes the irradiation field lamp 113 to irradiate visible light based on the visible light irradiation mode set by the mode setting function 242. The irradiation field lamp control function 244 is an example of a visible light control unit.

[0045] The irradiation field lamp control function 244 irradiates visible light in a manner corresponding to the visible light irradiation mode set by the mode setting function 242. That is, the irradiation field lamp control function 244 irradiates visible light from the irradiation field lamp 113 so that the current visible light irradiation mode can be identified. The irradiation field lamp control function 244 irradiates visible light of a color corresponding to the visible light irradiation mode set by the mode setting function 242.

[0046] For example, when the visible light irradiation mode is the illumination mode, the irradiation field lamp control function 244 causes the irradiation field lamp 113 to irradiate white visible light. Also, when the visible light irradiation mode is the illumination mode, the irradiation field lamp control function 244 causes the irradiation field lamp 113 to irradiate visible light onto an area specified by an operation accepted by the operation control function 241. This allows the operator to cause the irradiation field lamp 113 to irradiate visible light onto an area where the operator will be working, etc.

[0047] For example, when the visible light irradiation mode is the irradiation field lamp mode, the irradiation field lamp control function 244 irradiates warm-colored visible light. In the irradiation field lamp mode, the irradiation field lamp control function 244 irradiates visible light onto the first irradiation region to which the X-ray irradiator 11 is to irradiate X-rays. In other words, the irradiation field lamp control function 244 irradiates visible light onto the region of interest of the subject P.

[0048] For example, when the visible light irradiation mode is the X-ray visible mode and the X-ray irradiator 11 is irradiating X-rays, the irradiation field lamp control function 244 irradiates red visible light. In the irradiation field lamp mode, the irradiation field lamp control function 244 irradiates visible light onto the second irradiation region onto which the X-ray irradiator 11 is irradiating X-rays. In other words, the irradiation field lamp control function 244 irradiates visible light onto the region of interest of the subject P.

[0049] The irradiation field lamp control function 244 may distinguish the visible light irradiation mode not only by changing the color of the visible light but also by blinking the visible light, by changing the intensity of the visible light, or by combining the intensity, color, and blinking of the visible light. Furthermore, the irradiation field lamp control function 244 may distinguish the visible light irradiation mode by using a visible light irradiation mode other than those mentioned above. However, since the visible light irradiated in the X-ray visible mode notifies the range where X-rays are irradiated, it is preferable that the visible light be distinguishable from the visible light of the illumination mode or the irradiation field lamp mode.

[0050] Furthermore, the irradiation field lamp control function 244 causes the irradiation field lamp 113 to emit visible light with an illuminance based on the result of the illumination detection by the illumination detection function 243. Here, if the room in which the imaging device 10 is installed is bright, it is difficult for the operator to recognize the area illuminated by visible light. Therefore, when the illumination detection function 243 determines that the illumination device is on, the irradiation field lamp control function 244 causes the irradiation field lamp 113 to emit visible light with a higher illuminance than when the illumination device is off.

[0051] Furthermore, the irradiation field lamp control function 244 may cause the irradiation field lamp 113 to irradiate visible light in conjunction with the lighting in the room where the imaging device 10 is installed. For example, in the irradiation field lamp mode, the irradiation field lamp control function 244 may cause the irradiation field lamp 113 to irradiate visible light when the lighting in the room where the imaging device 10 is installed becomes dark as a trigger.

[0052] The setting change function 245 changes various settings related to the irradiation field lamp 113. For example, the setting change function 245 changes the color and illuminance of the visible light emitted by the irradiation field lamp 113 in the illumination mode, irradiation field lamp mode, and X-ray visible mode. The setting change function 245 also changes the time setting for ending the irradiation field lamp mode from 30 seconds to any time.

[0053] Next, various processes executed by the X-ray diagnostic apparatus 1 will be described.

[0054] 2 is a flowchart showing an example of illumination control processing executed by the X-ray diagnostic apparatus 1 according to this embodiment. The flowchart shown in FIG. 2 shows illumination control processing in a state where X-rays are not being irradiated.

[0055] In the initial state, the irradiation field lamp control function 244 turns off the irradiation field lamp 113 (step S1).

[0056] The operation control function 241 determines whether or not an operation to turn on the irradiation field lamp mode switch has been accepted (step S2).

[0057] When an operation to turn on the irradiation field lamp mode switch is accepted (step S2; Yes), the mode setting function 242 sets the irradiation field lamp mode (step S3).

[0058] The irradiation field lamp control function 244 irradiates the irradiation field with visible light indicating the irradiation field lamp mode (step S4). For example, the irradiation field lamp control function 244 irradiates the first irradiation region to which the X-ray irradiator 11 is to irradiate with X-rays with warm-colored visible light.

[0059] The operation control function 241 determines whether or not an operation to turn off the irradiation field lamp mode switch has been accepted (step S5). If an operation to turn off the irradiation field lamp mode switch has been accepted (step S5; Yes), the operation control function 241 determines whether or not the illumination mode switch is OFF (step S6).

[0060] If the illumination mode switch is OFF (step S6; Yes), the mode setting function 242 proceeds to step S1. That is, the irradiation field lamp control function 244 turns off the irradiation field lamp 113. If the illumination mode switch is ON (step S6; No), the mode setting function 242 proceeds to step S10. That is, the mode setting function 242 sets the illumination mode.

[0061] In step S5, if the operation to turn off the irradiation field lamp mode switch has not been received (step S5; No), the mode setting function 242 determines whether or not a set time has elapsed since visible light was irradiated in the irradiation field lamp mode (step S7). If the set time has not elapsed (step S7; No), the irradiation field lamp control function 244 proceeds to step S4.

[0062] If the set time has elapsed (step S7; Yes), the operation control function 241 determines whether the illumination mode switch is OFF (step S8). If the illumination mode switch is OFF (step S8; Yes), the mode setting function 242 proceeds to step S1. That is, the irradiation field lamp control function 244 turns off the irradiation field lamp 113.

[0063] If the lighting mode switch is ON (step S8; No), the mode setting function 242 proceeds to step S10. That is, the mode setting function 242 sets the lighting mode.

[0064] In step S2, if an operation to turn on the irradiation field lamp mode switch has not been accepted (step S2; No), the operation control function 241 determines whether or not an operation to turn on the illumination mode switch has been accepted (step S9). If an operation to turn on the illumination mode switch has not been accepted (step S9; No), the mode setting function 242 proceeds to step S2.

[0065] When an operation to turn on the lighting mode switch is accepted (step S9; Yes), the mode setting function 242 sets the lighting mode (step S10).

[0066] The irradiation field lamp control function 244 irradiates a given area with visible light indicating an illumination mode (step S11). For example, the irradiation field lamp control function 244 irradiates a given area with white visible light.

[0067] The operation control function 241 determines whether the illumination mode switch is OFF (step S12). If the illumination mode switch is OFF (step S12; Yes), the mode setting function 242 proceeds to step S1. That is, the irradiation field lamp control function 244 turns off the irradiation field lamp 113.

[0068] If the illumination mode switch is ON (step S12; No), the mode setting function 242 and the operation control function 241 determine whether the irradiation field lamp mode switch is ON (step S13).

[0069] If the irradiation field lamp mode switch is OFF (step S13; No), the mode setting function 242 proceeds to step S11.

[0070] If the irradiation field lamp mode switch is ON (step S13; Yes), the mode setting function 242 proceeds to step S3. That is, the mode setting function 242 sets the illumination mode.

[0071] With the above, the X-ray diagnostic apparatus 1 ends the illumination control process.

[0072] Fig. 3 is a flowchart showing an example of illumination control processing executed by the X-ray diagnostic apparatus 1 according to this embodiment. The flowchart shown in Fig. 3 shows illumination control processing in a state where X-rays are being irradiated.

[0073] The operation control function 241 determines whether or not an operation to turn on an X-ray irradiation switch that instructs irradiation of X-rays has been accepted (step S21). If an operation to turn on the X-ray irradiation switch has not been accepted (step S21; No), the operation control function 241 waits.

[0074] When an operation to turn on the X-ray irradiation switch is received (step S21; Yes), the irradiation field lamp control function 244 determines whether or not the X-ray visible mode has been set (step S22).

[0075] If the X-ray visible mode has been set (step S22; Yes), the irradiation field lamp control function 244 irradiates the second irradiation area irradiated with X-rays by the X-ray irradiation device 11 with visible light indicating the X-ray visible mode (step S23).

[0076] If the X-ray visible mode is not set (step S22; No), the irradiation field lamp control function 244 does not irradiate visible light (step S24). That is, the X-ray irradiator 11 irradiates X-rays but does not irradiate visible light indicating the X-ray visible mode.

[0077] The operation control function 241 determines whether or not an operation to turn off the X-ray irradiation switch that instructs irradiation of X-rays has been accepted (step S25). If an operation to turn off the X-ray irradiation switch has not been accepted (step S25; No), the operation control function 241 proceeds to step S22.

[0078] When an operation to turn off the X-ray irradiation switch is accepted (step S25; Yes), the irradiation field lamp control function 244 ends the irradiation of visible light indicating the X-ray visible mode (step S26). Also, the X-ray irradiator 11 ends the irradiation of X-rays.

[0079] With the above, the X-ray diagnostic apparatus 1 ends the X-ray visualization process.

[0080] As described above, the X-ray diagnostic apparatus 1 according to this embodiment has the irradiation field lamp 113. In the irradiation field lamp mode, the X-ray diagnostic apparatus 1 causes the irradiation field lamp 113 to irradiate the first irradiation region to be irradiated with X-rays by the X-ray irradiator 11 with visible light. In addition, in the illumination mode, the X-ray diagnostic apparatus 1 causes the irradiation field lamp 113 to irradiate an arbitrary region with visible light, regardless of the first irradiation region to be irradiated with X-rays by the X-ray irradiator 11. In this way, the X-ray diagnostic apparatus 1 also uses the irradiation field lamp 113 for illumination. Therefore, the X-ray diagnostic apparatus 1 can utilize the irradiation field lamp 113 for various purposes.

[0081] According to at least one of the embodiments described above, the irradiation field lamp 113 can be used for various purposes.
