RADIATION DETECTOR AND TOMOGRAPHIC EQUIPMENT PROVIDED WITH THE SAME

摘要

A radiation detector 1 according to this invention has a first reflector frame 7 and a second reflector frame 8. Each of scintillation counter crystals is inserted in a z-direction through the first reflector frame 7 and the second reflector frame 8, whereby two or more scintillation counter crystals are arranged in a first direction and a second direction to form a scintillation counter crystal layer 2A. A position of the first reflector frame 7 provided in the scintillation counter crystal layer 2A differs from a position of the second reflector frame 8 provided in the scintillation counter crystal layer 2A. With such construction, the radiation detector may be provided of significantly suppressed manufacturing costs without reducing spatial resolution and detecting sensitivity.
