ABSTRACT:
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.
