Silicon photomultiplier (SiPM) coupled scintillation detectors, are considered as promising tools for basic design of imaging instrumentation for the next generation PET, PET/MRI, SPECT and autoradiography scanners. The precise technical knowledge is inadequate, and still some challenges need to be addressed in order to successfully implement the SiPM technology in high resolution PET systems. Firstly, the advantages of SiPM pixel array 1:1 coupled crystal detector were obvious, and has minimized the position resolution errors of charge sharing in multiplexing circuits. However, in the system level, too many electronic channels have perplexed with complications, such as complex, messy electronics or dedicated ASIC chips. Multiplexing circuits were usually used to lower the complexity and cost of electronics, which has resulted in gradual deterioration of the performances of the detectors. Secondly, the light guide has become a necessity in high-resolution preclinical PET detector...

使用6×6 SiPM阵列的Trans-PET基本探测器模块II的设计和测量，用于小动物PET

硅光电倍增管（SiPM）耦合闪烁探测器被认为是用于下一代PET，PET / MRI，SPECT和放射自显影扫描仪的成像仪器基础设计的有前途的工具。精确的技术知识不足，为了成功地在高分辨率PET系统中实施SiPM技术，仍然需要解决一些挑战。首先，SiPM像素阵列1：1耦合晶体检测器的优点是显而易见的，并且使多路复用电路中电荷共享的位置分辨率误差最小。但是，在系统级别上，太多的电子通道陷入了复杂的局面，例如复杂，混乱的电子设备或专用ASIC芯片。多路复用电路通常用于降低电子设备的复杂性和成本，这导致检测器性能逐渐下降。其次，导光管已成为高分辨率临床前PET探测器的必需品。
