Description

Technical Field

[0001] The present invention relates to an X-ray fluoroscopic imaging device, and in particular to an X-ray fluoroscopic imaging device that moves a plurality of imaging device components. Background Art

[0002] Conventionally, an X-ray fluoroscopy device that moves a plurality of imaging device components is known. This X-ray fluoroscopy device is disclosed in, for example, Japanese Patent Application Laid-Open No. 2020-081410.

[0003] The X-ray radiographic apparatus described in Japanese Patent Publication No. 2020-081410 includes an examination table, a top plate moving mechanism, an arm, an arm moving mechanism, a control unit, and an operating unit. The examination table includes a top plate for placing a subject. In addition, the top plate moving mechanism is configured to move the top plate. In addition, the arm is configured to support the X-ray irradiation unit and the X-ray detection unit in a facing state. In addition, the arm moving mechanism is configured to perform a rotational action of rotating the arm around a vertical axis, a rotational action of rotating the arm around a horizontal axis, a sliding action of sliding the arm along an arc, and a horizontal movement action of moving the arm in a horizontal direction. In addition, the control unit is configured to cause the arm to perform at least one of a rotational action, a rotational action, a sliding action, and a horizontal movement action in conjunction with the movement action of the top plate in the horizontal direction by the top plate moving mechanism. In addition, the operating unit is configured to receive an operation input from an operator.

[0004] The X-ray imaging device disclosed in Japanese Patent Publication No. 2020-081410 is configured to be switchable between a linkage mode and a non-linkage mode, wherein the linkage mode is a mode in which the movement of the arm and the top plate are linked, and the non-linkage mode is a mode in which the movement of the arm and the top plate are not linked. When the linkage mode is selected, the operator operates the operating unit, and the movement of the arm and the top plate is linked.

[0005] Here, as in the X-ray imaging device (X-ray fluoroscopic imaging device) disclosed in Japanese Patent Laid-Open No. 2020-081410, when the arm (C-arm) automatically moves in conjunction with the movement of the top plate, when an operator who does not fully grasp the specifications of the device operates, the C-arm sometimes contacts the operator, technician, etc. That is, in the case of a structure in which other imaging device components such as the C-arm move in conjunction with the movement of the imaging device components specified such as the top plate, when an operator who does not fully grasp the specifications of the device operates the imaging device components, the imaging device components that the operator does not operate also move in conjunction, and sometimes the imaging device components that move in conjunction contact the operator, technician, etc. In addition, even if the operator has grasped the specifications of multiple imaging device components that move in conjunction, when the device determines which component moves in conjunction, sometimes the component that the operator does not expect moves. Therefore, it is desirable to have an X-ray fluoroscopic imaging device that can grasp which imaging device component moves in conjunction with the specified imaging device components without relying on the degree of grasp of the specifications of the device. Summary of the invention

[0006] The present invention is completed to solve the problems mentioned above. One purpose of the present invention is to provide an X-ray fluoroscopic imaging device that can enable an operator, technician, etc. to understand which imaging device component moves in conjunction with a specified imaging device component without relying on the degree of understanding of the specifications of the device.

[0007] In order to achieve the above-mentioned purpose, an X-ray fluoroscopic imaging device according to one aspect of the present invention comprises: an X-ray source that irradiates an object with X-rays; an X-ray detector that detects the X-rays irradiated from the X-ray source; a plurality of imaging device components, the plurality of imaging device components including a C-arm that holds the X-ray source and the X-ray detector in a state facing each other, a top plate for placing the object on the top, and a display unit that displays an X-ray image of the object; an input receiving unit that receives an operation input from an operator; a notification unit that notifies that a certain imaging device component among the plurality of imaging device components has moved; and a control unit that, when controlling to move a first imaging device component among the plurality of imaging device components based on a first operation input that moves the first imaging device component, or controlling to move a second imaging device component among the plurality of imaging device components that is different from the first imaging device component in conjunction with the movement of the first imaging device component, uses the notification unit to notify that the second imaging device component has moved.

[0008] In the X-ray fluoroscopic imaging device of the above-mentioned one aspect, the control unit is configured to: when the control is performed to make the second imaging device component move in conjunction with the movement of the first imaging device component, the control is performed to notify the second imaging device component of the movement by the notification unit. Thus, when the second imaging device component moves in conjunction with the movement of the first imaging device component, the notification unit notifies the second imaging device component of the movement, so that even if the operator does not know in advance that the second imaging device component moves in conjunction with the movement of the first imaging device component, the operator can know that the second imaging device component moves. In addition, even if the X-ray fluoroscopic imaging device determines the second imaging device component that moves in conjunction with the first imaging device component among the plurality of imaging device components, the notification unit can notify which imaging device component among the plurality of imaging device components is the second imaging device component, so for the operator who knows that the plurality of imaging device components move in conjunction, it is also possible to know which imaging device component moves. As a result, it is possible to provide an X-ray fluoroscopic imaging apparatus that allows an operator, a technician, or the like to understand which imaging apparatus component moves in conjunction with a predetermined imaging apparatus component, regardless of the degree of understanding of the specifications of the apparatus.

[0025] Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0026] (Overall structure of X-ray fluoroscopy device)

[0027] Reference Figure 1 7 to 7 illustrate an X-ray fluoroscopy apparatus 100 according to an embodiment of the present invention.

[0028] like Figure 1 As shown, the X-ray fluoroscopy apparatus 100 is an apparatus for imaging blood vessels of the subject 90. The blood vessels of the subject 90 are, for example, blood vessels of the head, blood vessels of the heart (coronary arteries), blood vessels of the abdomen, and blood vessels of the lower limbs of the subject 90.

[0029] The X-ray fluoroscopic imaging device 100 of the present embodiment includes an X-ray source 1, an X-ray detector 2, a plurality of imaging device components 3, an input receiving unit 4, a notification unit 5, and a computer 6. In addition, the X-ray fluoroscopic imaging device 100 of one embodiment includes a plurality of moving mechanisms 7 for moving the plurality of imaging device components 3.

[0030] The X-ray source 1 is configured to irradiate X-rays to the subject 90. The X-ray source 1 includes an X-ray tube (not shown). The X-ray tube is configured to overheat the X-ray tube by passing current through an anode and a cathode inside the tube, and to radiate X-rays when thermal electrons flying out of the cathode collide with the anode by applying a voltage between the anode and the cathode. In addition, the X-rays generated in the X-ray tube are irradiated toward the X-ray detector 2.

[0031] The X-ray detector 2 is configured to detect X-rays emitted from the X-ray source 1. The X-ray detector 2 is, for example, an FPD (Flat Panel Detector). The X-ray detector 2 is configured to receive X-rays emitted from the X-ray source 1 and transmitted through the subject 90, and convert the received X-rays into electrical signals. The X-ray detector 2 has an imaging element (not shown) having a plurality of pixels (partitions) inside, detects the intensity of the X-rays for each corresponding pixel, and converts the X-ray information (detection signal) of each pixel into an electrical signal (digital data) as a pixel value. The X-ray information converted into an electrical signal is sent to the control unit 60.

[0032] In addition, the imaging device component 3 in the present embodiment is a component that can be moved by the moving mechanism 7 when performing imaging. In the present embodiment, the plurality of imaging device component members 3 include a C-arm 30, a top plate 31, and a display unit 32.

[0033] The C-arm 30 has an arc shape. The C-arm 30 is configured to hold the X-ray source 1 and the X-ray detector 2 in a state of facing each other. Specifically, the X-ray source 1 is connected to one end of the C-arm 30, and the X-ray detector 2 is connected to the other end. The X-ray source 1 and the X-ray detector 2 are arranged by the C-arm 30 to face each other across the subject 90 lying on the top plate 31. In the present embodiment, the X-ray fluoroscopic imaging device 100 is a single-wing device having one C-arm 30.

[0034] The C-arm 30 is rotatably mounted on a C-arm moving mechanism 7 b described later. The C-arm 30 is configured to be capable of rotation and parallel movement by the C-arm moving mechanism 7 b.

[0035] The top plate 31 is configured to place the subject 90. The subject 90 is placed on the top plate 31 in such a manner that the long side direction of the top plate 31 is in the same direction as the direction connecting the head and feet of the subject 90. Figure 1 In the state, the long side direction of the top plate 31 is set to the X direction. In addition, the direction of the side where the head of the subject 90 is arranged is set to the X1 direction, and the direction of the side where the feet are arranged is set to the X2 direction. In addition, the short side direction of the top plate 31 (the left and right direction of the subject 90) perpendicular to the X direction is set to the Y direction. In addition, the direction of the right hand side of the subject 90 when the subject 90 is lying on his back is set to the Y1 direction, and the direction of the left hand side is set to the Y2 direction. In addition, the up and down directions perpendicular to the X direction and the Y direction are set to the Z direction. In addition, the top is set to the Z1 direction, and the bottom is set to the Z2 direction. The top plate 31 is configured to move in the X direction, the Y direction, and the Z direction by the top plate moving mechanism 7a in the state where the subject 90 is placed.

[0036] The display unit 32 is configured to display the X-ray image 10 of the subject 90. The display unit 32 includes, for example, a liquid crystal monitor.

[0037] The input receiving unit 4 is configured to receive an operation input by the operator. The input receiving unit 4 is provided on the top plate 31. The detailed structure of the input receiving unit 4 will be described later.

[0038] The notification unit 5 is configured to notify an operator, a technician, etc. that a certain imaging device component among the plurality of imaging device components 3 has moved. In the present embodiment, the notification unit 5 includes a light emitting unit 5a that outputs light to perform notification. The light emitting unit 5a includes, for example, an LED (Light Emitting Diode). Figure 1 As shown, the light emitting portion 5a is a linear light source extending along the X direction.

[0039] In the present embodiment, the notification unit 5 is provided on at least one of the moving mechanism 7 that moves the second imaging device component 3b and the second imaging device component 3b among the plurality of moving mechanisms 7. In the present embodiment, the notification unit 5 is provided on one side and the other side of the moving mechanism 7 that moves the second imaging device component 3b. Specifically, the notification unit 5 is provided on the C-arm moving mechanism 7b. In the present embodiment, the notification unit 5 is provided on the side surface on the Y1 direction side and the side surface on the Y2 direction side of the C-arm moving mechanism 7b.

[0040] The computer 6 includes a processor 6a and a storage unit 6b.

[0041] The processor 6a includes a controller 60 and an image processor 61. The processor 6a includes, for example, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an FPGA (Field-Programmable Gate Array) configured for image processing, etc. The control unit 60 is configured in the form of software as a functional block realized by the processor 6a executing various programs. The control unit 60 may also be configured by hardware by providing a dedicated processor (processing circuit).

[0042] In the present embodiment, the control unit 60 is configured to perform control of notifying the second imaging device component 3b to move by using the notification unit 5 when performing control to move the first imaging device component 3a among the plurality of imaging device components 3 based on the first operation input to move the first imaging device component 3a, and when performing control to move the second imaging device component 3b among the plurality of imaging device components 3 in conjunction with the movement of the first imaging device component 3a. In addition, the first imaging device component 3a is a component that moves by the operator's intentional operation. In addition, the second imaging device component 3b is a component that moves in conjunction with the first imaging device component 3a by the control of the control unit 60 regardless of the operator's intention. In the present embodiment, an example is described in which the first imaging device component 3a is the top plate 31 and the second imaging device component 3b is the C-arm 30. In addition, moving the second imaging device component 3b in conjunction with the first imaging device component 3a means moving the second imaging device component 3b by the operation to move the first imaging device component 3a. That is, moving the second imaging device component 3b in conjunction with the first imaging device component 3a means that the second imaging device component 3b also moves while the first imaging device component 3a moves.

[0043] The storage unit 6b is configured to store various programs executed by the processor 6a and the X-ray image 10 generated by the image processing unit 61. The storage unit 6b includes a nonvolatile memory such as a HDD (Hard Disk Drive) or a SSD (solid state drive).

[0044] The plurality of moving mechanisms 7 are configured to move at least two of the plurality of imaging device components 3. In the present embodiment, the plurality of moving mechanisms 7 include a top plate moving mechanism 7a that moves the top plate 31 and a C-arm moving mechanism 7b that moves the C-arm 30.

[0045] The top plate moving mechanism 7a is configured to be able to move the top plate 31 in the X direction, the Y direction, and the Z direction. The top plate moving mechanism 7a includes a direct motion mechanism in the X direction, a direct motion mechanism in the Y direction, and a direct motion mechanism in the Z direction.

[0046] The C-arm moving mechanism 7b is configured to be able to rotate and translate the C-arm 30. The detailed structure of the C-arm moving mechanism 7b will be described later.

[0047] (C-arm angle)

[0048] The X-ray fluoroscopic imaging device 100 is configured to Figure 2A The direction in which the X-rays are obliquely irradiated to the subject 90 from one end side (CRANIAL) or the other end side (CAUDAL) in the longitudinal section along the long side direction (X direction) of the top plate 31 on which the subject 90 is placed is different from Figure 2B The right anterior oblique (RAO: right anterior oblique), frontal, and left anterior oblique (LAO: left anterior oblique) views of the subject 90 shown are photographed in any direction obtained by combining them. Figure 2B The C-arm 30 is omitted in the figure.

[0049] (Photography location)

[0050] like Figure 3 As shown in FIG. 1 , the relative position (photographing position) of the C-arm 30 with respect to the top plate 31 varies depending on the part to be photographed. Figure 3 In the figure, the direction of the arrow is the direction in which the C-arm 30 is inserted relative to the top plate 31, the X-ray detector 2 is located on the side of the subject 90, that is, the front end side of the arrow, and the C-arm moving mechanism 7b is located on the end side of the arrow opposite to the front end side. The case where the C-arm 30 is configured along the long side direction (X direction) of the top plate 31 when viewed from above is set as the HOME position. In addition, the position where the C-arm 30 is configured in a manner tilted from the head side (X1 direction) of the subject 90 toward the foot side (X2 direction) and from the peripheral portion of the long side direction (X direction) of the top plate 31 toward the subject 90 is set as the MULTI position. That is, the MULTI position is a position where the C-arm 30 is configured in a manner tilted closer to the head side of the subject 90 than the center of the top plate 31 in the long side direction (X direction) of the top plate 31.

[0051] In addition, the position where the C-arm 30 is arranged along the short side direction (Y direction) of the top plate 31 from the side toward the center of the subject 90 when viewed from above is set as the SIDE position. That is, the SIDE position is a position where the C-arm 30 is arranged laterally (in a direction along the Y direction) near the center of the top plate 31 in the long side direction (X direction) of the top plate 31. And, the position moved from the SIDE position to the foot side (X2 direction) of the subject 90 is set as the PERI position. That is, the PERI position is a position where the C-arm 30 is arranged laterally in a manner closer to the foot side of the subject 90 than the center of the top plate 31 in the long side direction (X direction) of the top plate 31. For example, when shooting from the head to the chest of the subject 90, the HOME position is used. In addition, when shooting the lower limbs, the PERI position is used. In addition, when shooting the abdomen of the subject 90, the MULTI position or the SIDE position is used. Furthermore, the HOME position, the MULTI position, the SIDE position, and the PERI position are each used to determine the orientation of the C-arm 30 and the relative position of the C-arm 30 and the top plate 31 (the position coordinates of each of the C-arm 30 and the top plate 31 ).

[0052] (C-arm moving mechanism)

[0053] like Figure 4 As shown, the C-arm moving mechanism 7b includes an arm base 70, a rotating mechanism 71 and a moving mechanism 72. Figure 4 As shown, the rotation mechanism 71 rotates the C-arm 30 around the axis of the rotation shaft 11, which is a line extending in the long-side direction (X direction) of the top plate 31 connecting the head and feet of the subject 90. In addition, the rotation mechanism 71 is configured to be able to rotate the C-arm 30 along the circumferential direction 80 of the C-arm 30 with the line extending in the left-right direction of the subject 90, that is, the short-side direction (Y direction) of the top plate 31 as the axis. The rotation mechanism 71 includes, for example, a motor or the like.

[0054] The moving mechanism 72 is mounted on the arm base 70. The arm base 70 is moved horizontally by the moving mechanism 72, thereby enabling the C-arm 30 to move horizontally. The moving mechanism 72 includes: a first rotating portion 72a, which is set on the ground 91; and a second rotating portion 72b, which is rotatably held by the first rotating portion 72a and holds the arm base 70 in a rotatable manner. The first rotating portion 72a includes a base shaft 12 and an intermediate shaft 13 provided at a position away from the base shaft 12. The second rotating portion 72b includes a horizontal rotation shaft 14.

[0055] The base shaft 12 and the intermediate shaft 13 are respectively rotational shafts oriented in a direction perpendicular to the ground 91. In addition, the horizontal rotation shaft 14 is also a rotational shaft oriented in a direction perpendicular to the ground 91. Thus, the moving mechanism 72 can combine the rotation around the axis of the base shaft 12, the rotation around the axis of the intermediate shaft 13, and the rotation around the axis of the horizontal rotation shaft 14 to horizontally move the arm base 70 and the C-arm 30 to a desired position.

[0056] (Input receiving unit)

[0057] like Figure 5 As shown, the input receiving unit 4 includes a top operating unit 4a, a C-arm operating unit 4b, an X-ray detector operating unit 4c, and a moving mode selecting unit 4d.

[0058] The top plate operation unit 4a is configured to move the top plate 31 while the operator is pressing the top plate operation unit 4a in a state where a predetermined movement mode is selected by the movement mode selection unit 4d. That is, the top plate operation unit 4a is configured to move the top plate 31 to the movement destination (position) of the top plate 31 in advance while the operator is pressing the top plate operation unit 4a. The top plate operation unit 4a includes, for example, a button.

[0059] The C-arm operation unit 4b is configured to move the C-arm 30 while the operator operates the C-arm operation unit 4b. The C-arm operation unit 4b includes, for example, a lever switch. The detailed configuration of the C-arm operation unit 4b will be described later.

[0060] The X-ray detector operating unit 4c is configured to move the X-ray detector 2 in the front-rear direction in the irradiation axis direction of the X-rays while the operator operates the X-ray detector operating unit 4c. The X-ray detector operating unit 4c includes, for example, a lever switch. The detailed structure of the X-ray detector operating unit 4c will be described later.

[0061] The movement mode selection unit 4d is configured to be able to receive input of the movement mode of the imaging device component 3. The movement mode selection unit 4d includes, for example, a button. The movement mode of the imaging device component 3 includes, for example, a femoral approach mode for photographing the lower limbs, a memory mode for moving the C-arm 30 and the top plate 31 to a preset position, and a free mode for moving the C-arm 30 and the top plate 31 to an arbitrary position. The operator presses the movement mode selection unit 4d of the desired movement mode to operate at least one of the top plate operating unit 4a, the C-arm operating unit 4b, and the X-ray detector operating unit 4c, thereby moving the imaging device component 3 according to the desired movement mode.

[0062] like Figure 6As shown, the C-arm operating unit 4b includes a first lever unit 40, a rotation selection button 41, and a horizontal movement selection button 42. By tilting the first lever unit 40 while the operator presses the rotation selection button 41, the C-arm 30 can be tilted to a desired angle after combining CRANIAL or CAUDAL with RAO or LAO. In addition, by tilting the first lever unit 40 while the operator presses the horizontal movement selection button 42, the C-arm 30 can be moved horizontally.

[0063] In addition, if Figure 6 As shown, the X-ray detector operating unit 4c includes a second lever unit 43 and an X-ray detector moving button 44. When the operator presses the X-ray detector moving button 44, the X-ray detector 2 can be moved forward and backward in the irradiation axis direction of X-rays by tilting the second lever unit 43.

[0064] (Movement of top plate and C-arm)

[0065] Next, refer to Figure 7A to Figure 7C A configuration in which the C-arm 30 moves in conjunction with the movement of the top plate 31 will be described. Figure 7A to Figure 7C The example shown shows that the movement mode selection unit 4d (see Figure 5 ) Movement of the C-arm 30 and top plate 31 when the femoral approach mode is selected.

[0066] like Fig. 7A As shown, when the femur approach mode is selected with the C-arm 30 inserted from the head side (X1 direction side) of the subject 90 , the control unit 60 moves the top plate 31 in the direction of arrow 81 to image the lower limbs of the subject 90 .

[0067] At this time, if Fig. 7A As shown in FIG. 1 , since the C-arm 30 is arranged on the side of the moving direction (X1 direction) of the top plate 31, the top plate 31 cannot be moved in this state. Although the operator can move the top plate 31 in the direction of the arrow 81 by moving the C-arm 30, the number of operations of the operator increases, and the burden increases. Therefore, in the femoral approach mode, when the operation of moving the top plate 31 is performed, the C-arm 30 is moved in conjunction with the movement of the top plate 31. Specifically, as shown in FIG. Figure 7B As shown in FIG. 8 , the C-arm 30 is rotated in conjunction with the movement of the top plate 31 in the direction of arrow 82. The control unit 60 controls the top plate 31 to move in the direction of arrow 81 while rotating the C-arm 30 to a position where it does not interfere with the top plate 31. Figure 7C As shown, the table top 31 is moved to a position for imaging the lower limbs of the subject 90. In the present embodiment, the control unit 60 controls the table top moving mechanism 7a and the C-arm moving mechanism 7b to move the table top 31 and the C-arm 30 simultaneously and in parallel.

[0068] Here, if the operator does not understand that the C-arm 30 moves in conjunction with the movement of the top plate 31 in the femur approach mode, the C-arm 30 may come into contact with the operator, the technician, and the like.

[0069] (Notification processing by the control unit)

[0070] Therefore, in the present embodiment, the control unit 60 is configured to perform the following control: when receiving the input of the movement mode (femur approach mode) in which the second imaging device component 3b (C-arm 30) moves in conjunction with the movement of the first imaging device component 3a (top plate 31) as the second operation input, the notification unit 5 is used to perform the notification in advance before the first imaging device component 3a (top plate 31) starts to move based on the first operation input. Specifically, in the present embodiment, the control unit 60 performs the following control: when receiving the operation input in which the top plate 31 moves as the first operation input, the notification unit 5 (light emitting unit 5a) is used to perform the notification before the top plate 31 as the first imaging device component 3a starts to move. That is, in the present embodiment, the control unit 60 is configured to perform the control of notifying the C-arm 30 to move in conjunction with the movement of the top plate 31 as the first imaging device component 3a by the C-arm moving mechanism 7a.

[0071] In addition, in the present embodiment, the control unit 60 does not receive an operation input from the operator to move the second photographic device component 3b (C-arm 30), and determines whether to move the second photographic device component 3b in conjunction with the movement of the first photographic device component 3a (top plate 31). Specifically, when the control unit 60 receives the second operation input, it determines whether to move the second photographic device component 3b (C-arm 30) in conjunction with the movement of the first photographic device component 3a (top plate 31). Here, in the case of a structure in which the control unit 60 determines whether to move the second photographic device component 3b, even an operator who has mastered the specifications for moving a plurality of photographic device components 3 in conjunction cannot grasp which photographic device component 3 moves in conjunction. Therefore, in this embodiment, the control unit 60 is configured to: when the second photographic device component 3b is moved in conjunction with the movement of the first photographic device component 3a (top plate 31), notification is performed using the notification unit 5; when the second photographic device component 3b (C-arm 30) is not moved in conjunction with the movement of the first photographic device component 3a, notification is not performed using the notification unit 5.

[0072] Specifically, when the control unit 60 moves the first imaging device component 3a (top plate 31) to a predetermined position based on the first operation input, the control unit 60 obtains the position before the movement of the second imaging device component 3b (C-arm 30), that is, the current position 50, and the position after the movement of the second imaging device component 3b (C-arm 30), that is, the target position 51, and when the current position 50 and the target position 51 are different, the control unit 60 controls the notification unit 5 to make a notification, and when the current position 50 and the target position 51 are the same, the notification by the notification unit 5 is not made. In addition, the control unit 60 obtains the current position 50 from a potentiometer or the like provided in a driving unit (not shown) of the C-arm moving mechanism 7b. In addition, the control unit 60 obtains the target position 51 from the storage unit 6b based on the selected movement mode.

[0073] (Notification method of the Notification Department)

[0074] In the present embodiment, the control unit 60 controls the output of light from the light emitting unit 5a (notification unit 5) to notify the second imaging device component 3b (C-arm 30) of movement. In the present embodiment, the control unit 60 performs the following control: notifying the second imaging device component 3b of movement by making the light emitting unit 5a emit light in a different manner. Specifically, the control unit 60 is configured to perform the following control: when the X-ray fluoroscopic imaging device 100 is in operation, the light emitting unit 5a is controlled to be in a lit state, and when the C-arm 30 moves in conjunction with the movement of the top plate 31, the light emitting unit 5a is controlled to change from a lit state to a flashing state to perform notification.

[0075] (Notification Processing)

[0076] Next, refer to Figure 8 The following describes a process in which the control unit 60 of the present embodiment causes the notification unit 5 to notify that the second imaging device component 3 b (C-arm 30 ) has moved.

[0077] In step 101, the control unit 60 determines whether there is a second operation input in a mode (femur approach mode) in which the second imaging device component 3b (C-arm 30) and the first imaging device component 3a (top plate 31) move in conjunction with each other. If there is a second operation input, the process proceeds to step 102. If there is no second operation input, the control unit 60 repeats the process of step 101.

[0078] In step 102 , the controller 60 acquires the current position 50 of the C-arm 30 . In the process of step 102 , the control unit 60 acquires the angle and position coordinates of the C-arm 30 from the C-arm moving mechanism 7 b as the current position 50 of the C-arm 30 .

[0079] In step 103 , the control unit 60 acquires the target position 51 of the C-arm 30 . In the process of step 103 , the control unit 60 acquires the angle and position coordinates of the C-arm 30 after the movement from the storage unit 6 b as the target position 51 of the C-arm 30 .

[0080] In step 104, the control unit 60 determines whether the current position 50 is the same as the target position 51. If the current position 50 is the same as the target position 51, the process proceeds to step 106. That is, if the current position 50 is the same as the target position 51, the control unit 60 does not perform notification by the notification unit 5 because the C-arm 30 does not move. On the other hand, if the current position 50 is not the same as the target position 51, the process proceeds to step 105.

[0081] In step 105, the control unit 60 notifies by the notification unit 5. Specifically, the control unit 60 notifies by causing the notification unit 5 (light emitting unit 5a) to output light. Specifically, the control unit 60 notifies by changing the light emission pattern of the light emitting unit 5a from a lit state to a blinking state.

[0082] In step 106, the control unit 60 determines whether there is a first operation input. If there is a first operation input, the process proceeds to step 107. If there is no first operation input, the control unit 60 repeats the process of step 106.

[0083] In step 107 , the control unit 60 controls the top plate moving mechanism 7 a and the C-arm moving mechanism 7 b to move the first imaging device constituent member 3 a (top plate 31 ) and the second imaging device constituent member 3 b (C-arm 30 ).

[0084] In step 108, the control unit 60 determines whether the first imaging device component 3a (top plate 31) and the second imaging device component 3b (C-arm 30) have moved to the specified position. If the top plate 31 and the C-arm 30 have moved to the specified position, the process proceeds to step 109. If the top plate 31 and the C-arm 30 have not moved to the specified position, the process proceeds to step 107.

[0085] In step 109, the control unit 60 stops the notification by the notification unit 5 (light emitting unit 5a). Then, the process ends. If the current position 50 is the same as the target position 51, the process of step 109 is omitted.

[0086] In addition, either the process of step 102 or the process of step 103 may be performed first.

[0087] In this embodiment, the notification process performed by the control unit 60 is substantially performed simultaneously with the input of the second operation input for selecting the movement mode. In other words, the control unit 60 starts the notification during the period from accepting the selection of the movement mode to the start of the operation (acceptance of the first operation input).

[0088] (Effects of this embodiment)

[0089] In this embodiment, the following effects can be obtained.

[0090] In the present embodiment, as described above, the X-ray fluoroscopic imaging device 100 includes: an X-ray source 1 that irradiates an object 90 with X-rays; an X-ray detector 2 that detects the X-rays irradiated from the X-ray source 1; a plurality of imaging device components 3, the plurality of imaging device components 3 including a C-arm 30 that holds the X-ray source 1 and the X-ray detector 2 in a state facing each other, a top plate 31 for placing the object 90, and a display unit 32 that displays an X-ray image 10 of the object 90; an input receiving unit 4 that receives an operation input from an operator; and a notification unit 5 that notifies the plurality of imaging device components 3 causes a certain photographic device constituent component 3 to move; and a control unit 60, which, when controlling to move the first photographic device constituent component 3a (top plate 31) among the plurality of photographic device constituent components 3 based on a first operation input for moving the first photographic device constituent component 3a, and controlling to move a second photographic device constituent component 3b (C-arm 30) different from the first photographic device constituent component 3a among the plurality of photographic device constituent components 3 in conjunction with the movement of the first photographic device constituent component 3a, uses the notification unit 5 to notify the second photographic device constituent component 3b of the movement.

[0091] Thus, when the second imaging device component 3b (C-arm 30) moves in conjunction with the movement of the first imaging device component 3a (top plate 31), the notification unit 5 notifies that the second imaging device component 3b has moved, so that even if the operator does not know in advance that the second imaging device component 3b moves in conjunction with the movement of the first imaging device component 3a, the operator can know that the second imaging device component 3b has moved. In addition, even if the X-ray fluoroscopy imaging device 100 determines that the second imaging device component 3b moves in conjunction with the first imaging device component 3a among the plurality of imaging device components 3, the notification unit 5 can be used to notify that a certain imaging device component 3 among the plurality of imaging device components 3 is the second imaging device component 3b, so that the operator who knows that the plurality of imaging device components 3 move in conjunction can also know which imaging device component 3 has moved. As a result, it is possible to provide an X-ray fluoroscopy imaging device 100 that allows an operator, a technician, etc. to know which imaging device component 3 moves in conjunction with a specified imaging device component 3, regardless of the degree of knowledge of the specifications of the device.

[0092] In addition, in the above-mentioned embodiment, by configuring as follows, the following effects can be further obtained.

[0093] That is, in the present embodiment, as described above, the control unit 60 is configured to perform the following control: when receiving an input of a movement mode in which the second imaging device component 3b (C-arm 30) moves in conjunction with the movement of the first imaging device component 3a (top plate 31) as the second operation input, the notification unit 5 is used to perform a notification in advance before the first imaging device component 3a starts to move based on the first operation input. Thus, when the second operation input is received, the second imaging device component 3b is notified of movement, so that the second imaging device component 3b can be notified of movement before the second imaging device component 3b starts to move. As a result, the operator can reliably grasp the movement of the second imaging device component 3b before the second imaging device component 3b starts to move.

[0094] In addition, in the present embodiment, as described above, the control unit 60 is configured to determine whether to move the second imaging device component 3b (C-arm 30) in conjunction with the movement of the first imaging device component 3a (top plate 31) when the second operation input is received, and to notify the second imaging device component 3b by using the notification unit 5 when the second imaging device component 3b is moved in conjunction with the movement of the first imaging device component 3a, and not to notify the second imaging device component 3b by using the notification unit 5 when the second imaging device component 3b is not moved in conjunction with the movement of the first imaging device component 3a. Here, when the second operation input is received, when the notification unit 5 is not determined whether to move the second imaging device component 3b in conjunction with the movement of the first imaging device component 3a, the notification unit 5 is used to notify even when the second imaging device component 3b is not moved in conjunction with the movement of the first imaging device component 3a. Therefore, there is a case where the operator cannot accurately grasp whether the second imaging device component 3b has moved. By setting the configuration in which notification is made when the second imaging device component 3b moves and notification is not made when the second imaging device component 3b does not move as described above, notification of movement of the second imaging device component 3b is made only when the second imaging device component 3b moves in conjunction with the first imaging device component 3a. Therefore, when notification is made by the notification unit 5, the operator can understand that the second imaging device component 3b must have moved. As a result, unlike the configuration in which notification is made even when the second imaging device component 3b does not move, confusion of the operator can be suppressed.

[0095] In addition, in the present embodiment, as described above, the control unit 60 is configured to obtain the current position 50, which is the position before the movement of the second imaging device component 3b (C-arm 30), and the target position 51, which is the position after the movement of the second imaging device component 3b, when the first imaging device component 3a (top plate 31) is moved to a predetermined position based on the first operation input, and to control the notification unit 5 to perform notification when the current position 50 and the target position 51 are different, and not to perform notification using the notification unit 5 when the current position 50 and the target position 51 are the same. Thus, the control unit 60 can easily determine whether to perform notification using the notification unit 5 by determining whether the acquired current position 50 and the target position 51 are different or the same.

[0096] In addition, in the present embodiment, as described above, a plurality of moving mechanisms 7 are further provided, wherein the plurality of moving mechanisms 7 move at least two of the plurality of imaging device components 3, and the notification unit 5 is provided in at least one of the moving mechanism 7 (C-arm moving mechanism 7b) that moves the second imaging device component 3b and the second imaging device component 3b (C-arm 30) among the plurality of moving mechanisms 7. Thus, since the notification unit 5 is provided in one of the second imaging device component 3b that moves in conjunction with the first imaging device component 3a (top plate 31) and the moving mechanism 7 that moves the second imaging device component 3b, it is possible to make a notification using the notification unit 5 near the member that is actually moved. As a result, unlike a configuration in which the notification is made by displaying the fact that the second imaging device component 3b has moved on a monitor or the like that is fixedly arranged at a predetermined position, even when the operator is in a position where the monitor or the like cannot be seen, it is possible to make the operator, technician, or the like understand that the second imaging device component 3b has moved.

[0097] In addition, in the present embodiment, as described above, the notification unit 5 is provided on one side and the other side of the moving mechanism 7 (C-arm moving mechanism 7b) that moves the second imaging device component 3b (C-arm 30). Thus, since the notification unit 5 is provided on both sides of the moving mechanism 7 that moves the second imaging device component 3b, the operator, technician, etc. can grasp the notification using the notification unit 5 regardless of which side of the moving mechanism 7 that moves the second imaging device component 3b the operator is on.

[0098] In addition, in the present embodiment, as described above, the top plate moving mechanism 7a and the C-arm moving mechanism 7b are further provided, the top plate moving mechanism 7a is used to move the top plate 31, and the C-arm moving mechanism 7b is used to move the C-arm 30, and the control unit 60 is configured to: when the C-arm moving mechanism 7b is used to control the C-arm 30 as the second imaging device component 3b to move in conjunction with the top plate 31 as the first imaging device component 3a, the control unit 60 is configured to control the C-arm 30 to move by the notification unit 5. Thus, the notification unit 5 notifies the C-arm 30 to move in conjunction with the movement of the top plate 31, and therefore, in the X-ray fluoroscopic imaging device 100 in which the C-arm 30 moves in conjunction with the movement of the top plate 31, it is preferable to set the structure of the present embodiment.

[0099] In addition, in the present embodiment, as described above, the notification unit 5 includes a light emitting unit 5a that notifies by outputting light. Thus, the light output from the light emitting unit 5a can make the operator, technician, etc. easily grasp visually that the second imaging device component 3b has moved. In addition, since the second imaging device component 3b is notified by the light output from the light emitting unit 5a, for example, unlike a structure that notifies by displaying the second imaging device component 3b moving on the display unit 32, even if the operator does not correctly grasp the information displayed on the display unit 32, the operator, technician, etc. can intuitively grasp that the second imaging device component 3b has moved.

[0100] [First Modification of the Present Embodiment]

[0101] Reference Fig. 9 A first modification example will be described with reference to Fig. 10. In addition, the same reference numerals are given to the same structures as those in the above-mentioned embodiment, and the description thereof will be omitted.

[0102] The X-ray fluoroscopy apparatus 200 of the first modified example is different from the X-ray fluoroscopy apparatus 100 of the above embodiment in that it includes a computer 26 instead of the computer 6 and a display unit moving mechanism 7c for moving the display unit 32. The computer 26 of the first modified example is different from the computer 6 of the above embodiment in that it includes a processor 6c instead of the processor 6a. The processor 6c of the first modified example is different from the processor 6a of the above embodiment in that the processor 6c includes a controller 62 instead of the controller 60.

[0103] The display unit moving mechanism 7c is configured to move the display unit 32 in the X direction and the Y direction. The display unit moving mechanism 7c includes, for example, a direct motion mechanism in the X direction and a direct motion mechanism in the Y direction. In addition, the display unit moving mechanism 7c may be configured to move the display unit 32 in the Z direction.

[0104] In addition, in the first modification, Fig. 9 As shown, the notification unit 5 (light emitting unit 5 a ) is provided in the display unit 32 .

[0105] In the first variant, if Figures 10A to 10C As shown, the control unit 62 controls the display unit 32 to move in the direction of arrow 84 in conjunction with the movement of the C-arm 30 when the display unit 32 is arranged within the rotation track of the C-arm 30 when the C-arm 30 is rotated along arrow 83 .

[0106] In the first modified example, the control unit 62 is configured to perform the following control: when the display unit 32 as the second imaging device component 3b is moved by the display unit moving mechanism 7c and the C-arm 30 as the first imaging device component 3a is moved by the C-arm moving mechanism 7b, the notification unit 5 (see Fig. 9 ) notifies the display unit 32 that movement has occurred.

[0107] In the first modified example, the control unit 62 determines whether to move the second imaging device component 3b (display unit 32) in conjunction with the movement of the first imaging device component 3a (C-arm 30) when receiving an operation input for moving the C-arm 30. In addition, the control unit 62 is configured to perform notification using the notification unit 5 when the display unit 32 is moved in conjunction with the movement of the C-arm 30, and not to perform notification using the notification unit 5 when the display unit 32 is not moved in conjunction with the movement of the C-arm 30. Specifically, the control unit 62 is configured to acquire a current position 52, which is a position before the movement of the display unit 32, and a target position 53, which is a position after the movement of the display unit 32, and to control the notification unit 5 to notify when the current position 52 and the target position 53 are different, and not to perform notification using the notification unit 5 when the current position 52 and the target position 53 are the same. In addition, the control unit 62 acquires the current position 52 from the display unit moving mechanism 7c. In addition, the control unit 62 acquires the target position 53 from the storage unit 6b.

[0108] The other structures of the first modified example are the same as those of the above-mentioned embodiment.

[0109] (Effects of the First Modification Example)

[0110] In the first modified example, as described above, the X-ray fluoroscopic imaging apparatus 200 further includes the C-arm moving mechanism 7b for moving the C-arm 30 and the display unit moving mechanism 7c for moving the display unit 32, and the control unit 62 is configured to perform the following control: when the display unit 32 as the second imaging device component 3b is moved by the display unit moving mechanism 7c in conjunction with the movement of the C-arm 30 as the first imaging device component 3a by the C-arm moving mechanism 7b, the display unit 32 is notified of movement by the notification unit 5. Thus, since the display unit 32 is notified of movement in conjunction with the movement of the C-arm 30 by the notification unit 5, in the X-ray fluoroscopic imaging apparatus 200 in which the display unit 32 moves in conjunction with the movement of the C-arm 30, it is preferable to set it to the structure of the first modified example.

[0111] The other effects of the first modification example are the same as those of the above-mentioned embodiment.

[0112] [Second Modification of the Present Embodiment]

[0113] use Fig.11 The second modification example will be described. Note that the same reference numerals are used for the same structures as those in the above-described embodiment, and description thereof will be omitted.

[0114] like Fig.11 As shown, the X-ray fluoroscopy apparatus 300 of the second modification example is different from the X-ray fluoroscopy apparatus 100 of the present embodiment in that the notification unit 5 includes a speaker 5 b for outputting notification sound and a computer 36 is provided instead of the computer 6 .

[0115] The computer 36 of the second modification example is different from the computer 6 of the above embodiment in that it includes a processor 6d instead of the processor 6a. The processor 6d is different from the processor 6a of the above embodiment in that it includes a control unit 63 instead of the control unit 60.

[0116] The control unit 63 of the second modified example is configured to notify by outputting a notification sound from the speaker 5b when the second imaging device component 3b moves in conjunction with the first imaging device component 3a. The notification sound includes a warning sound and a warning message based on sound. In addition, in the second modified example, the control unit 63 may use both the light emitting unit 5a and the speaker 5b to notify, or may not use the light emitting unit 5a and only use the speaker 5b to notify.

[0117] The other structures of the second modified example are the same as those of the above-mentioned embodiment.

[0118] (Effects of the Second Modification Example)

[0119] In the second modification, as described above, the notification unit 5 of the X-ray fluoroscopy apparatus 300 further includes a speaker 5b for outputting a notification sound. Thus, the notification sound from the speaker 5b allows the operator, technician, etc. to easily understand the movement of the second imaging device component 3b by hearing.

[0120] In addition, other effects of the second modification example are the same as those of the above-mentioned embodiment.

[0121] [Modifications]

[0122] In addition, the embodiments disclosed this time should be considered to be illustrative in all aspects and not restrictive. The scope of the present invention is not shown by the description of the above embodiments, but by the claims, and also includes all changes (modifications) within the meaning and scope equivalent to the claims.

[0123] For example, the above-mentioned embodiment and the second modification example show a configuration example in which the control unit controls the C-arm 30 to move in conjunction with the movement of the top plate 31, and the above-mentioned first modification example shows a configuration example in which the control unit controls the display unit 32 to move in conjunction with the movement of the C-arm 30, but the present invention is not limited thereto. For example, the control unit may also be configured to move the display unit 32 in conjunction with the movement of the C-arm 30 when the display unit 32 interferes with the movement of the C-arm 30 when the C-arm 30 is moved in conjunction with the movement of the top plate 31. That is, the control unit may also be configured to move both the C-arm 30 and the display unit 32 in conjunction with the movement of the top plate 31. In the case where the control unit is configured to move both the C-arm 30 and the display unit 32 in conjunction with the movement of the top plate 31, the notification unit 5 may be provided on both the C-arm 30 and the display unit 32 or on both the display unit moving mechanism 7c and the C-arm moving mechanism 7b.

[0124] In addition, in the above-mentioned embodiment and the second modified example, the first imaging device component 3a is the top plate 31, and the second imaging device component 3b is the C arm 30. In the first modified example, the first imaging device component 3a is the C arm 30, and the second imaging device component 3b is the display unit 32. However, the present invention is not limited thereto. The first imaging device component 3a can be any one of the C arm 30, the top plate 31, and the display unit 32 as long as the operator wants to move it. In addition, the second imaging device component 3b can be any one of the C arm 30, the top plate 31, and the display unit 32 as long as it moves in conjunction with the movement of the first imaging device component 3a. In addition, the C arm 30 is the component with a large range of movement and a large weight among the C arm 30, the top plate 31, and the display unit 32. Therefore, among the C arm 30, the top plate 31, and the display unit 32, the component that has the greatest influence when it comes into contact with the operator, technician, etc. is the C arm 30. Therefore, the notification unit 5 may be provided at least on the C-arm 30 or the C-arm moving mechanism 7 b .

[0125] In addition, which of the plurality of imaging device components 3 is the first imaging device component 3a and which is the second imaging device component 3b is determined according to the movement mode when the plurality of imaging device components 3 are moved. That is, according to the movement mode, the C-arm 30, the top plate 31, and the display unit 32 can be either the first imaging device component 3a or the second imaging device component 3b. Therefore, in a structure in which it is possible to change the first imaging device component 3a and the second imaging device component 3b according to the movement mode selected by the operator, it is sufficient to provide the notification unit 5 for each of the plurality of imaging device components 3 or the plurality of moving mechanisms 7.

[0126] In addition, in the above-mentioned embodiment, the first modification, and the second modification, an example in which the C-arm 30 is a single-wing type is shown, but the present invention is not limited thereto. For example, a double-wing type in which two C-arms 30 are provided may be adopted.

[0127] In addition, in the above-mentioned embodiment, the first modification and the second modification, a configuration example in which the notification using the notification unit 5 is performed when the C-arm 30 moves in conjunction with the movement of the top plate 31 is shown, but the present invention is not limited thereto. For example, the control unit may also be configured to perform the notification using the notification unit 5 when the top plate 31 moves in conjunction with the movement of the C-arm 30. That is, the control unit may be configured to perform the notification using the notification unit 5 when the second imaging device component 3b among the plurality of imaging device components 3 moves in conjunction with the first imaging device component 3a. If configured in this way, even when the X-ray fluoroscopic imaging device 100 determines that the imaging device component 3 is to be moved, the operator can be notified of the imaging device component 3 that is to be moved in conjunction. As a result, it is possible to grasp which imaging device component 3 is to be moved in conjunction with the prescribed imaging device component 3, regardless of the operator's grasp of the specifications of the device.

[0128] In addition, in the above-mentioned embodiment, the first modification and the second modification, a configuration example is shown in which the notification unit 5 is provided for the second imaging device component 3b to notify that the second imaging device component 3b has moved, but the present invention is not limited thereto. For example, the following configuration may be adopted: the second imaging device component 3b is notified of movement, and the notification unit 5 is also provided for the first imaging device component 3a, and the notification is performed using the notification unit 5 when the first imaging device component 3a has moved.

[0129] In addition, in the above-mentioned embodiment, the first variant and the second variant, a structural example in which the control unit determines whether to move the second photographic device component 3b in conjunction with the movement of the first photographic device component 3a is shown, but the present invention is not limited to this. For example, the control unit may also be configured not to determine whether to move the second photographic device component 3b in conjunction with the movement of the first photographic device component 3a. That is, the control unit may also be configured to perform notification using the notification unit 5 based on the second operation input. However, there is the following situation: in the case of a structure in which notification is performed based on the second operation input, notification using the notification unit 5 is performed even when the second photographic device component 3b does not move. If notification using the notification unit 5 is performed even when the second photographic device component 3b does not move, the operator will be confused. Therefore, the control unit is preferably configured to determine whether to move the second photographic device component 3b in conjunction with the movement of the first photographic device component 3a.

[0130] In addition, in the above-mentioned embodiment, the first modification and the second modification, a configuration example is shown in which the control unit determines whether to make a notification using the notification unit 5 based on the current position and the target position of the second imaging device component 3b, but the present invention is not limited thereto. For example, the control unit may also be configured to determine whether to make a notification using the notification unit 5 based on the position of the first imaging device component 3a and the position of the second imaging device component 3b. That is, the control unit may also be configured to determine whether to make a notification using the notification unit 5 by determining whether to move the second imaging device component 3b based on the position of the first imaging device component 3a and the position of the second imaging device component 3b.

[0131] In addition, in the above-mentioned embodiment and the second modified example, the notifying unit 5 is provided on the moving mechanism 7, but the present invention is not limited thereto. The notifying unit 5 may also be provided on the second imaging device component 3b. The notifying unit 5 may be provided anywhere as long as it can notify the second imaging device component 3b to move in conjunction with the movement of the first imaging device component 3a.

[0132] In addition, in the above-mentioned embodiment and the first modified example, the control unit notifies the second imaging device component 3b of the movement by switching the light emitting unit 5a from the lighting state to the flashing state, but the present invention is not limited to this. For example, the control unit may also perform the following control: notifying the second imaging device component 3b of the movement by making the color of the light output by the light emitting unit 5a different. As long as the second imaging device component 3b can be notified of the movement by the light output from the light emitting unit 5a, the notification method is not limited.

[0133] In addition, in the above-mentioned embodiment and the first modified example, the configuration example in which the notification unit 5 includes the light emitting unit 5a is shown, and in the second modified example, the configuration example in which the notification unit 5 includes the speaker 5b is shown, but the present invention is not limited thereto. For example, the notification unit 5 may also include a monitor for displaying the meaning that the second imaging device component 3b has moved.
