multilayer scintillation crystal and PET detector

摘要

A multilayer scintillation crystal (1) comprising an n-layer array of scintillation crystals and an uncut continuous scintillation crystal inside the m layer. The bottom layer of the multilayer scintillation crystal (1) is a continuous scintillation crystal. Increasing the continuous scintillation crystal between the array scintillation crystal and the photoelectric detector system (2) contributes to the diffusion of photons of the scintillation light, and by optimizing the thickness of the continuous scintillation crystal, the photoelectric detector The scintillation light distribution received by the device can have more abundant energy deposition information. By utilizing this abundant energy deposition information in accordance with the corresponding information extraction algorithm, it is possible to more accurately obtain the energy deposition information in the scintillation crystal of γ photons.
