Light output analyzes of scintillator crystal pins and array for PET detector modules

A new Zemax model has been developed that is capable to predict reliably the light output of scintillator crystal pins of different configurations, i.e. geometry, surface finish and reflector material. Model parameters are measured wavelength dependent characteristics of the scintillator crystal, re...

Description
Summary:A new Zemax model has been developed that is capable to predict reliably the light output of scintillator crystal pins of different configurations, i.e. geometry, surface finish and reflector material. Model parameters are measured wavelength dependent characteristics of the scintillator crystal, reflector and PMT's parts. Good agreement has been demonstrated between simulated and measured results using 21 different pin configurations and testing the same pin configuration in a sample array.
