Abstract
A PET scanning system includes a plurality of detector modules, each having an array of pixelated scintillators, the array having N rows of pixelated scintillators, and M columns of pixelated scintillators. Each detector module includes a first set of N light guides optically coupled to the top surface that accumulate optical signals, and a second set of M light guides optically coupled to the bottom surface that accumulate optical signals. Each light guide is coupled to a light sensor which converts optical signals into analog electrical outputs. A processor is coupled to outputs from the first set and the second set, the processor configured to determine which pixelated scintillator within the array had a gamma ray interact therewith, and its depth of interaction, based on the outputs. Thus, gamma ray detection in an array of M×N scintillator pixels is accomplished using only M+N channels.
