Gamma camera system with composite solid state detector

摘要

A composite solid-state detector for utilization within gamma cameras and the like. The detector's formed of an array of detector crystals, the opposed surfaces of each of which are formed incorporating an impedance-derived configuration for determining one coordinate of the location of discrete impinging photons upon the detector. A combined read-out for all detectors within the composite array thereof is achieved through a row and column interconnection of the impedance configurations. Utilizing the noted read-outs for respective sides of the discrete crystals, a resultant time-constant characteristic for the composite detector crystal array remains essentially that of individual crystal detectors.
