Investigation of Interactional Properties of γrays and Scintillator Units for PET
-
摘要: γ射线与晶体单元的相互作用特性对于PET探测器的研制有着重要的参考意义. 通过实验测得了不同能量的γ射线在BGO, CsI, NaI 3种闪烁晶体中的探测效率、 能量分辨率等相互作用特性参数, 并与蒙特卡洛模拟结果进行了比较. 结果给出了最适合PET探测器的晶体单元. It’s important for development of PET detector that the interaction effect of γrays and scintillator units are studied. The detection efficiencies and energy resolutions of γrays for BGO, CsI and NaI crystal detector units are measured. Geant4 Monte Carlo simulations are compared with the experimental results. The results of the best detection units for PET detector are presented.Abstract: It’s important for development of PET detector that the interaction effect of γrays and scintillator units are studied.
