A multilayer scintillation crystal and a PET detector

Japanese Patent JP5909027

B2

A multilayer scintillation crystal (1) comprises n layers of array scintillation crystals and m layers of continuous scintillation crystals which have uncut inner parts, both n and m being integers greater than or equal to 1 and a sum of n and m being smaller than or equal to 10. The array scintillation crystals are formed by strip-type scintillation crystals arranged along the width and length directions, the array scintillation crystals and the continuous scintillation crystals are sequentially coupled along the height direction of the strip-type scintillation crystals to form the multilayer scintillation crystal (1), and the continuous scintillation crystals are located at the bottom of the multilayer scintillation crystal (1). The adding of the continuous scintillation crystals between the array scintillation crystals and a photoelectric detector system (2) facilitates photon diffusion of a scintillating light, and through optimization design of the thickness of the continuous scintillation crystals, the distribution of the scintillating light received by the photoelectric detector carries more abundant energy deposition information. More accurate energy deposition information of ³ photons in the scintillation crystal can be obtained through full utilization of the abundant energy deposition information by using a corresponding information extraction algorithm.
