    摘要： A radiological imaging apparatus of the present invention comprises an image pickup device and a medical examinee holding device that is provided with a bed. The image pickup device includes a large number of radiation detectors and radiation detector support plates. A large number of radiation detectors are mounted around the circumference of a through-hole and arranged in the axial direction of the through-hole. The radiation detectors are arranged in three layers formed radially with respect to the center of the through-hole and mounted on the lateral surfaces of the radiation detector support plates. Since the radiation detectors are not only arranged in the axial direction and circumferential direction of the through-hole but also arrayed in the radial direction, it is possible to obtain accurate information about a γ-ray arrival position in the radial direction of the through-hole (the positional information about a radiation detector from which a γ-ray image pickup signal is output). The use of accurate information about γ-ray arrival increases the tomogram accuracy. As a result, the present invention enhances the tomogram accuracy, that is, the PET examination accuracy.

    摘要： A radiological imaging apparatus comprising a semiconductor detector unit in which a plurality of semiconductor radiation detection elements are installed on a detector mounted substrate in a matrix to constitute a detector unit. A plurality of detector units are releasably mounted on a fixing substrate. This mounting is carried out mating a coupling screw with a threaded hole formed in the detector mounted substrate, the coupling screw being inserted through a through-hole formed in the fixing substrate. The detector mounted substrate is provided with a pair of positioning pins. The positioning pins are inserted into positioning holes, respectively, formed in the fixing substrate, to position the detector unit.
