When the fluoroscopic switch 2 </ b> A is turned on, X-rays are emitted from the X-ray tube according to the irradiation conditions transmitted to the main control unit 15. The X-rays irradiated in this case are X-rays with irradiation conditions suitable for diagnosing the diagnosis target part of the subject. For example, the X-ray has a large pulse width and a high pulse rate, and the irradiated X-ray dose is larger than when the positioning fluoroscopic switch 16 is turned on, so that a clear image suitable for diagnosis can be obtained. .

  After X-rays suitable for diagnosing the diagnosis target region of the subject are irradiated from the X-ray tube, the X-ray is irradiated to the subject, and the top plate on which the subject is placed is moved, and the diagnosis target portion is moved. Is diagnosed (S36).
