Perfromance Evaluation of a Highly Reflective Multilayer Optical Film (MLOF) for a Reflector of Scintillators for PET

Abstract

I evaluated the performance of a highly reflective multi-layer optical film (MLOF) for a reflector of scintillators for PET by comparing it with a white Teflon tape. The scintillators used for evaluation were BGO, GSO, LSO, and LGSO. Scintillators covered by the MLOFs showed similar light outputs as those rapped by the Teflon tapes. In addition to the highly reflective characteristic, the thin thickness of the MLOF makes it possible to arrange the scintillators with minimum dead spaces, and it is concluded that the MLOF is quite useful for reflector for PET scintillators.
