摘要： A positron emission tomography apparatus installs a plurality of detector units in the circumference of a bed. The detector unit installs a plurality of combined substrates including detectors, analogue ASICs, and a digital ASIC and a voltage adjustment device inside a housing. A partition plate installed inside the housing separates the region inside the housing into a first region installed with the combined substrates and a second region installed with the voltage adjustment device. The partition plate blocks noise generated in the voltage adjustment device so as not to affect γ-ray detection signals outputted from the detectors, thereby preventing the effect of the noise generated in the voltage adjustment device toward γ-ray detection signals and shortening the examination time.

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： 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.
