New developments in PET detector technology

The research on PET detector is a very active and highly innovative field. The main research interests of PET detector include improving performances of scintillation crystal detectors, investigating new detectors being suitable for multimodality imaging (e. g., PET/CT and PET/MRI), meeting needs of TOF and DOI technologies in order to promote their development and application. In this paper, new developments in PET detector technology about scintillation crystal, photodetector and semiconductor detector are introduced and the most potential detector design scheme in the future is brought forward.
