Abstract：The performance of PET for small animal examination is largely dependent on the performance of the detector. Therefore, the designing for detector units with high resolution and high sensitivity becomes one of crucial issues in the investigation of small animal PET. This paper reviews the characteristics and performance of ring or flat panel detectors and a number of commercial PET for small animal examination. We made analysis with and summarized the development of the PET detector technology from components of a detector unit such as crystal and PMT. The development directions of determining new DOI, exploring new semiconductor detectors and designing for universal electronics are discussed as well.

Key words： small animal PET detector depth of interaction (DOI) methods semiconductor detectors universal electronics
