摘要
PET detector modules are provided within a multi-dimensional magnetic field, to confine the range of emitted positrons from an object being imaged to improve spatial resolution of reconstructed PET images. Each module includes a number of independent, optically isolated detectors. Each detector includes an array of scintillator crystals read out by an array of APDs (avalanche photodiodes).
