The image data generation unit 61 generates photographed image data based on the X-ray projection data output from the X-ray detection unit 2 and stores it in the image data storage unit 62 (step S8).

  Then, after the captured image data used for diagnosis or treatment of the subject P is obtained, when an operation of pressing the fluoroscopic OFF button 8db of the image operation unit 8d of the operation unit 8 is performed, the system control unit 9 generates a high voltage. The unit 4, the X-ray generation unit 1, the X-ray detection unit 2, and the image data processing unit 6 are instructed to stop the operation.

  Then, the examination of the subject P is completed when the operations of the high voltage generator 4, the X-ray generator 1, the X-ray detector 2, and the image data processor 6 are stopped (step S9).

  After the examination is completed, the captured image data of the subject P is displayed on the display unit 7 or an external display device, and diagnosis or treatment by a doctor is performed.

  According to the embodiment of the present invention described above, the tube voltage input device 82a, the tube current input device 82b, and the time input device 82c that can perform an input operation of one of the fluoroscopic and imaging conditions that are X-ray irradiation conditions are provided. By using the input device 82a, 82b, or 82c to switch the input device, the input device 82a, 82b, or 82c can perform the input operation of the other condition.

  Further, the input identification unit 85 is disposed in the vicinity of each input device 82a, 82b, 82c, and the first display identification unit 86 is disposed in the vicinity of the first display unit 83, whereby the perspective by each input device 82a, 82b, 82c. When a condition input operation is possible, the input identifying unit 85 and the first display identifying unit 86 can be identified and displayed in the first color.

  Further, by arranging the second display identification unit 87 in the vicinity of the second display unit 84, the input identification unit 85 and the second display identification can be performed when the photographing conditions can be input by the input devices 82a, 82b, and 82c. The part 87 can be identified and displayed in the second color.

  As a result, the time required for the inspection operation can be shortened and erroneous operation can be prevented.
