Abstract

PURPOSE:To prolong the life of a detector by using a nondirectional solid detector array having a simple structure for a CT scanner having a multichannel radiation detector. CONSTITUTION:Nondirectional solid detectors 4 are provided, and these detectors 4 are arranged continuously in a straight line in relation to a pulse fan beam. The above detectors 4 are formed of a compound semiconductor single- crystal substrate 5 having a high atomic number, such as CdTe. This substrate 5 is processed in the shape of a comb and an ohmic junction electrode 70 formed of Pt, etc. is arranged on the back surface of the substrate 5, while Shottky barrier junction electrodes 81, 82... formed of Al, etc. are arranged at the top parts of a remaining part (tip parts of teeth of the pectination-formed substrate). In a multichannel radiation detector 5 having such a constitution, the radiation to be measured falls from the side of the Shottky barrier junction electrodes 81, 82.... Since the detector 5 is formed as a solid detector, the life thereof is semipermanent unless no radiation damage is caused.
