摘要
PET设备中探测器的研发,一直是很活跃且具有高创新性的领域。提高现有基于闪烁晶体探测器的性能,研究适用于多模式成像设备(PET/CT和PET/MRI)的新型探测器,满足TOF和DOI技术的需求并促进其发展应用,构成PET探测器的几个主要研究方向。介绍了PET探测器在闪烁晶体、光电探测器和半导体探测器等方面的最新进展,指出未来最有潜力的探测器设计方案。
The research on PET detector is a very active and highly innovative field. The main research in- terests of PET detector include improving performances of scintillation crystal detectors, investigating new detectors being suitable for multimodality imaging （e. g., PET/CT and PET/MRI）, meeting needs of TOF and DOI technologies in order to promote their development and application. In this paper, new de- velopments in PET detector technology about scintillation crystal, photodetector and semiconductor detec- tor are introduced and the most potential detector design scheme in the future is brought forward.
