摘要： A radiological imaging apparatus allowing semiconductor radiation detectors to be easily replaced with new ones and densely arranged. Terminals (31cjk) and (33cjk) are provided on a bottom surface of a detector aggregate (40mn) including a plurality of semiconductor radiation detectors (1); the terminals is connected to electrodes (3 and 4) of the detectors (1). A plurality of zero insertion force connectors (56) are provided on a connecting device (33jk) installed on a support substrate (32h). The terminals (31cjk and 33cjk) are detachably attached to the zero insertion force connectors (56) to mount the detector aggregates (40mn) that are the semiconductor radiation detectors (1), on the support substrate (32h). When the detector aggregates (40mn) are attached to the zero insertion force connectors (56), since no frictional force acts on the terminals, the size of the gap between the detector aggregates (40mn) is reduced.

摘要： Each semiconductor radiation detector used for a nuclear medicine diagnostic apparatus (PET apparatus) is constructed with an anode electrode A facing a cathode electrode C sandwiching a CdTe semiconductor member S which generates charge through interaction with γ-rays. Then, a thickness t of the semiconductor member S sandwiched between these mutually facing anode electrode A and cathode electrode C is set to 0.2 to 2 mm. Furthermore, the devices are mounted (laid out) on substrates in such a way that the distance (distance of conductor) between the semiconductor radiation detector and an analog ASIC which processes the signal detected by this detector is shortened. Furthermore, the substrates on which the detectors are mounted are housed in a housing as a unit (detector unit).

摘要： A γ-ray signal processing section 60′ determines a detection time of a γ ray based on a α-ray detection signal outputted from a semiconductor radiation detector for detecting the γ ray, and determines the energy of the γ ray. Then, a time correction circuit 70 obtains, based on the energy of the γ ray, a detection value of the detection time that corresponds to the energy of the γ ray from a time correction table indicating the relationship between the energy of the γ ray and the correction value of the detection time of the γ ray, and corrects the detection time according to the obtained correction value of the detection time. Coincidence counting is performed on the γ ray in a coincidence counting circuit 80 based on the corrected detection time.

摘要： A radiological imaging apparatus of the present invention includes an X-ray source for emitting an X-ray, a γ-ray detecting section for outputting a detection signal of a γ-ray, and an X-ray detecting section for outputting a detecting signal of an X-ray. The X-ray source moves around a bed for placing an examinee. The γ-ray detecting section has a plurality of radiation detectors aligned in the longitudinal direction of the bed and placed around the bed. The X-ray detecting section is positioned in a region formed between one end and the other end of the γ-ray detecting section in the longitudinal direction of the bed. The X-ray source is also positioned in the region. Since the X-ray detecting section is placed in the region, it is possible to accurately combine a PET image and an X-ray computed tomographic image.
