Performance comparison of depth-encoding detectors based on dual-ended readout and different SiPMs for high-resolution PET applications.

Performance comparison of depth-encoding detectors based on dual-ended readout and different SiPMs for high-resolution PET applications. Phys Med Biol. 2019 Apr 24;: Authors: Du J, Bai X, Cherry SR Abstract Silicon photomultipliers (SiPMs) are widely used in positron emission tomography (PET), however, SiPMs from different vendors vary in their performance characteristics. In addition, the specifications provided by the manufacturers are measured under different operating conditions and using different test setups, making it difficult to choose the optimal device for a specific application using the published specifications. In this work, we evaluated four state-of-the-art 8 × 8 arrays of ~ 3 mm × 3 mm SiPMs from SensL, KETEK, and Hamamatsu for high-resolution dual-ended readout detectors using the same experimental setup and procedures. The results showed that all four SiPM arrays are excellent candidates for high-resolution PET applications, although some interesting differences in performance were noted.
