Since the orientation of the X-ray image displayed on the unit 10 is different from the actual orientation of the patient 41, operations such as movement of the C-arm 13 cannot be suitably performed.

  In such a case, the operator 44 presses one of the switches 51 and 52 displayed in the switch display area 10b of the display unit 10 disposed in the main body 11 of the photographing unit 1. As a result, the X-ray image displayed in the image display area 10a in the display unit 10 disposed in the main body 11 of the photographing unit 1 and the monitor carriage are obtained by the action of the image rotation unit 63 of the image processing unit 61 shown in FIG. Among the X-ray images displayed on the display unit 17 in FIG. 2, only the X-ray image displayed in the image display area 10a in the display unit 10 disposed in the main body 11 of the imaging unit 1 is rotated. Then, the operator 44 switches the switch 51 when the X-ray image displayed in the image display area 10a in the display unit 10 disposed in the main body 11 of the imaging unit 1 is arranged in the direction shown in FIG. , 52 is stopped. Thereby, the direction of the X-ray image displayed in the image display area 10 a in the display unit 10 disposed in the main body 11 of the imaging unit 1 can be matched with the viewing direction of the patient 41 by the operator 44.

  Note that, as indicated by a virtual line in FIG. 3, the operator 44 is disposed on the main body 11 of the photographing unit 1 even when the operator 44 operates the photographing unit 1 at a position lateral to the main body 11 of the photographing unit 1. In order to make the orientation of the X-ray image displayed in the image display area 10a of the display unit 10 coincide with the orientation of the patient 41, the X-ray image may be arranged in the direction shown in FIG.

  In the above description, the case where the orientation of the X-ray image displayed on the display unit 10 disposed on the main body 11 of the imaging unit 1 is matched with the orientation of the patient 41 has been described. 11, when the direction of the X-ray image displayed on the display unit 10 disposed on the display carriage 10 is to coincide with the direction of the X-ray image displayed on the display unit 17 of the monitor carriage 2, the operator 44 switches the switch 51, By operating 52, the direction of the X-ray image displayed on the display unit 10 is adjusted to such a direction. That is, when the operator 44 is operating the imaging unit 1 at a position behind the main body 11 of the imaging unit 1 indicated 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. 3, when the operator 44 operates the imaging unit 1 at a position on the side of the main body 11 of the imaging unit 1, an X-ray image displayed on the display unit 10 is displayed. The direction is the direction shown in FIG.

  As described above, according to the fluoroscopic imaging apparatus according to the present invention, the X-ray image displayed on the display unit 10 in the main body 11 of the imaging unit 1 is rotated and displayed on the display unit 10 of the main body 11. Therefore, the operator 44 can easily recognize the X-ray image displayed on the display unit 10. Thereby, operations such as positioning of the C-shaped arm 13 can be easily performed.

  Next, another embodiment of the X-ray fluoroscopic 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 fluoroscopic apparatus according to the second embodiment of the present invention, and FIG. 8 is a schematic side view thereof.

  In the embodiment described above, the X-ray image displayed on the display unit 10 in the main body 11 of the imaging unit 1 is rotated by the image rotation unit 63 of the image processing unit 61 shown in FIG. On the other hand, in this 2nd Embodiment, the structure which rotates the display part 10 itself in the main body 11 of the imaging | photography part 1 with the display part rotation mechanism 53 is employ | adopted. The display unit rotating mechanism 53 is disposed 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 in the main body 11 of the imaging unit 1. Thereby, operations such as positioning of the C-shaped arm 13 can be easily performed.
