Abstract
In a gamma camera, to improve resolution, primary scintillations resulting from absorption of gamma ray photons in a scintillator crystal are intercepted by the input face of a channel amplifier plate in which the primary scintillations excite a photocathode to emit electrons which are multiplied in the respective channels and reconverted to secondary scintillations in a phosphorescent output screen from which the brighter secondary scintillations are coupled to an array of photodetectors which produce signals that are used to determine the x and y coordinates of the scintillations. The secondary scintillation positions correspond with the primary scintillations in the crystal because the channels keep them aligned.
