Gamma camera plate assembly for PET and SPECT imaging

摘要

A gamma camera scintillation crystal plate assembly and method that may be used for both PET (positron emission tomography) and SPECT (single photon emission computer tomography). The crystal plate assembly includes two or more crystals which are optically coupled and tuned so as to control the energy position of the photopeaks at an output surface of the plate assembly. The crystals are tuned by various means including varying the surface finishes and material selection.
