To be equipped.

The control unit 60 may be arranged inside the main body 11 of the photographing unit 1 or may be arranged inside the trolley main body 15 of the monitor trolley 2. Alternatively, the control unit 60 may be divided into the inside of the main body 11 in the photographing unit 1 and the inside of the trolley main body 15 in the monitor trolley 2.

Next, in the above-mentioned X-ray fluoroscopic imaging device, an X-ray image displayed on the image display area 10a of the display unit 10 arranged in the main body 11 of the imaging unit 1 and the display unit 17 of the monitor carriage 2 will be described. do. FIG. 6 is an explanatory diagram for explaining the directions of the X-ray images displayed on the image display area 10a of the display unit 10 arranged on the main body 11 of the photographing unit 1 and the display unit 17 of the monitor carriage 2. be.

As shown in FIG. 3, when performing fluoroscopy with surgery, the doctor 42 performs the surgery at the position closest to the patient 41 on the operating table 19. At this time, the X-ray image of the patient 41 is displayed on the display unit 17 of the monitor carriage 2, for example, facing the direction in which the doctor 42 directly looks at the patient 41. That is, as shown in FIG. 3, the directions A and B of the patient 41 as seen from the doctor 42 are the same as the viewing direction of the doctor 42 even on the display unit 17 on the monitor carriage 2 as shown in FIG. 6 (a). Displayed in the direction. This X-ray image is created by the X-ray image display unit 62 of the image processing unit 61 shown in FIG. Then, the display unit 10 arranged on the main body 11 of the photographing unit 1 also usually displays an X-ray image facing the same direction as the display unit 17 on the monitor carriage 2.

At this time, when the operator 44 operates the photographing unit 1 at a position behind the main body 11 of the photographing unit 1, which is shown by a solid line in FIG. 3, the display arranged on the main body 11 of the photographing unit 1 is displayed. Since the orientation of the X-ray image displayed on the unit 10 is different from the orientation of the actual patient 41, it is not possible to suitably perform operations such as movement of the C-shaped arm 13.

In such a case, the operator 44 presses any of the switches 51 and 52 displayed in the switch display area 10b of the display unit 10 arranged on the main body 11 of the photographing unit 1. As a result, the X-ray image displayed in the image display area 10a of the display unit 10 arranged in the main body 11 of the photographing unit 1 and the monitor carriage by the action of the image rotating unit 63 of the image processing unit 61 shown in FIG. Of the X-ray images displayed on the display unit 17 in 2, only the X-ray image displayed in the image display area 10a on the display unit 10 arranged on the main body 11 of the photographing unit 1 is rotated. Then, the operator 44 switches 51 when the X-ray image displayed in the image display area 10a of the display unit 10 arranged in the main body 11 of the photographing unit 1 is arranged in the direction shown in FIG. 6B. , 52 stops pressing. This makes it possible to match the direction of the X-ray image displayed in the image display area 10a of the display unit 10 arranged in the main body 11 of the photographing unit 1 with the viewing direction of the patient 41 by the operator 44.

As shown by the virtual line in FIG. 3, even when the operator 44 operates the photographing unit 1 at a position on the side of the main body 11 of the photographing unit 1, it is arranged on the main body 11 of the photographing unit 1. In order to match the direction of the X-ray image displayed in the image display area 10a of the display unit 10 with the direction of the patient 41, the X-ray image may be arranged in the direction shown in FIG. 6 (b).

In the above description, the case where the orientation of the X-ray image displayed on the display unit 10 arranged on the main body 11 of the imaging unit 1 is matched with the orientation of the patient 41 has been described, but the main body of the imaging unit 1 has been described. When it is desired to match the direction of the X-ray image displayed on the display unit 10 arranged on the display 11 with the direction of the X-ray image displayed on the display unit 17 on the monitor carriage 2, the operator 44 uses the switch 51. By operating 52, the orientation of the X-ray image displayed on the display unit 10 is adjusted to such an orientation. That is, when the operator 44 operates the photographing unit 1 at a position behind the main body 11 of the photographing unit 1, which is shown by a solid line in FIG. 3, the orientation of the X-ray image displayed on the display unit 10 is changed. , The orientation is the same as the orientation of the X-ray image displayed on the display unit 17 shown in FIG. 6A. Further, as shown by a virtual line in FIG. 3, when the operator 44 operates the photographing unit 1 at a position on the side of the main body 11 of the photographing unit 1, the X-ray image displayed on the display unit 10 is displayed. The orientation is the orientation shown in FIG. 6 (c).

As described above, according to the X-ray fluoroscopic imaging apparatus according to the present invention, the X-ray image displayed on the display unit 10 of the main body 11 of the photographing unit 1 is displayed on the display unit 10 of the main body 11 by rotating the X-ray image. The direction of the X-ray image can be set to a direction suitable for the operator 44, and the operator 44 can easily recognize the X-ray image displayed on the display unit 10. This makes it possible to easily perform operations such as positioning of the C-shaped arm 13.

Next, another embodiment of the X-ray fluoroscopic imaging apparatus according to the present invention will be described. FIG. 7 is a perspective view of the vicinity of the display unit 10 in the X-ray fluoroscopy apparatus according to the second embodiment of the present invention, and FIG. 8 is a side schematic view thereof.

In the above-described embodiment, the image rotating unit 63 of the image processing unit 61 shown in FIG. 5 rotates the X-ray image displayed on the display unit 10 of the main body 11 of the photographing unit 1. On the other hand, in the second embodiment, the display unit 10 itself in the main body 11 of the photographing unit 1 is rotated by the display unit rotation mechanism 53. The display unit rotation mechanism 53 is arranged between the main body 11 of the photographing unit 1 and the display unit 10, and has a configuration for rotating the display unit 10 with respect to the main body 11.

Even when such a configuration is adopted, the operator 44 can easily recognize the X-ray image displayed on the display unit 10 by rotating the display unit 10 on the main body 11 of the photographing unit 1. This makes it possible to easily perform operations such as positioning of the C-shaped arm 13.
