摘要: 本文介绍了硅光电倍增器（SiPM）研制所取得的最新进展及PET应用中SiPM的研究现状。新器件实验室(NDL)制造出光敏面积为2.2 mm×2.2 mm的SiPM器件，并将SiPM与2 mm×2 mm×10 mm的LYSO晶体耦合，实验结果显示，器件探测FDG 511 keV光子的能量分辨率达12.83%，符合时间分辨率达564 ps。Abstract: The recent research and progress of the silicon photomultiplier (SiPM) in PET application were introduced. The 2.2 mm×2.2 mm SiPM with bulk integrated quenching resistor was developed by Novel Device Laboratory (NDL). The SiPM was coupled with the 2 mm×2 mm×10 mm LYSO crystal. The result shows an energy resolution of SiPM is 12.8% and its coincidence time resolution is 564 ps by using FDG 511 keV photon.
