HIGH RESOLUTION DETECTOR ARRAY FOR GAMMA-RAY IMAGING

摘要

A gamma ray detection and locating system (10) comprising an array of scintillator crystals (12) conneted to a multichannel photomultiplier tube (18) by discrete optical fibers (16), each fiber connecting a single crystal (14) to a corresponding specific location on the face of the photomultiplier tube. Also described is an improved system for identifying the location of specific electrodes in the photomultiplier tube receiving electrons generated by photons flowing from the crystal along the fiber to the tube.
