硅光电倍增管（SiPM）广泛应用于正电子发射断层扫描（PET）中，然而，来自不同供应商的SiPM在其性能特性方面有所不同。此外，制造商提供的规格是在不同的操作条件下使用不同的测试设置进行测量的，因此很难使用已发布的规格为特定应用选择最佳设备。在这项工作中，我们使用相同的实验设置和程序评估了来自SensL，KETEK和Hamamatsu的四个最先进的8 x 8阵列，这些阵列类似于3 x 3 mm（2）SiPM，用于高分辨率双端读出探测器。结果表明，所有四个SiPM阵列都是高分辨率PET应用的优秀候选者，尽管注意到了一些有趣的性能差异。
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 x 8 arrays of similar to 3 x 3 mm(2) 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.
