Development of depth encoding small animal <scp>PET</scp> detectors using dual‐ended readout of pixelated scintillator arrays with Si<scp>PM</scp>s

Abstract

Four high resolution depth encoding small animal PET detectors were developed using dual-ended readout of pixelated scintillator arrays with SiPMs. The performance results show that those detectors can be used to build a small animal PET scanner to simultaneously achieve uniform high spatial resolution and high sensitivity.
