近年来，伽马射线探测技术在医学应用、空间和环境的ˆ领域发挥着非常重要的作用。像素化探测器和电子器件是实现高分辨率伽马射线探测器所必需的。尤其是高分辨率正电子发射断层扫描(PET)系统已经成为像素伽马射线探测器发展的驱动力。像素伽马探测器由颗粒状晶体和具有高集成电路(ASIC)的光电探测器组成，用于处理大量的通道。本文对这些技术的最新发展进行了综述。
Recently gamma ray detection technologies become very important in the ˆelds of medical application, space, and environment. Pixelated detectors and electronics are necessary to achieve high-resolution gamma ray detectors. Especially high resolution PET (positron emission tomography) system has been a driving force for developing pixel gamma-ray detectors. A pixel gamma detector is composed of granulated crystals and photo-detectors with highly integrated circuits (ASIC) to process the large number of channels. Recent development of these technologies is reviewed here.
