Patent ID: 6920196

Claim:
A radiological imaging apparatus comprising: a bed on which a subject is laid; an image pickup apparatus; the image pickup apparatus comprising: an X-ray source which is used to irradiate the subject with X-rays; an X-ray source moving apparatus for moving the X-ray source in a circumferential direction of a hole portion into which the bed is inserted; a plurality of first radiation detectors, disposed around the hole portion, for not substantially detecting γ-rays from the subject but detecting X-rays, and outputting a first detecting signal which is a detecting signal of X-rays; and a second radiation detector, disposed around the hole portion, for detecting γ-rays and X-rays from the subject and outputting both the first detecting signal and a second detecting signal which is a detecting signal of γ-rays; a first signal processing apparatus for processing the first detecting signal outputted from the first radiation detector; and a second signal processing apparatus for processing the second detecting signal outputted from the second radiation detector.
