    摘要: The image pickup apparatus of the radiological imaging apparatus of the present invention includes many detector units, a ring-shaped detector support member and an X-ray source circumferential transport apparatus. Each of the detector units is attached to the detector support section in a detachable manner. A plurality of radiation detectors provided for the detector units are arranged in three layers in the radius direction of the detector support member and in three columns in the axial direction of the detector support member. Since the radiation detectors are arranged in three layers in the radius direction, it is possible to recognize the detection position of radiation in the radius direction in detail. Furthermore, since the detector units are attached in a detachable manner, it is easy to replace damaged radiation detectors.

    摘要: An image pickup apparatus of a radiological imaging apparatus includes a plurality of radiation detectors arranged in a ring form around a through hole section formed on a casing into which an examinee is inserted. An X-ray source unit having an X-ray source moves in a circumferential direction of the through hole section along a ring-shaped guide rail provided on the casing. Each radiation detector outputs both an X-ray detection signal which is a detection signal of X-rays that have passed through the examinee and a γ-ray detection signal which is a detection signal of γ-rays radiated from the examinee caused by radiopharmaceutical. A computer creates an X-ray computed tomographic image data based on the X-ray detection signal and a PET image data based on the γ-ray detection signal and creates fused tomographic image data using the X-ray computed tomographic image data and the PET image data.

    摘要: An imaging apparatus of a radiological imaging apparatus is provided with a first and a second radiation detectors disposed around a hole portion into which a bed is inserted. The first radiation detector includes a detecting portion formed of GaAs of a square having a side of 5 mm and having a thickness of 2 mm. The second radiation detector includes a detecting portion formed of CdTe of a cube having a side of 5 mm. The first radiation detector detects X-rays emitted from an X-ray source and transmitted through an examinee and does not detect γ-rays emitted from the examinee. The second radiation detector detects above X-rays and γ-rays. An X-ray signal processing apparatus processes an X-ray image signal from the first radiation detector and outputs intensity information thereof. A signal discriminating apparatus processes a γ-ray image signal from the second radiation detector and outputs a pulse signal. Thus, the radiological imaging apparatus capable of carrying out radiation examination of the subject by using X-rays and γ-rays can be simplified.
