The recent development of the LaBr3(Ce) crystals makes very attractive their application as a system of gamma imaging for SPET applications mainly due to their excellent scintillation properties. In this work, we use Monte Carlo simulations, in order to model the optical behavior of three continuous crystal configurations. Our goal is a better understanding of the intrinsic properties of a gamma camera based on LaBr3(Ce) crystals, coupled to a position sensitive photomultiplier tube. To this aim, the spatial and energy resolutions obtainable from optimum photodetection conditions are investigated.

Abstract
The recent development of the LaBr3(Ce) crystals makes very attractive their application as a system of gamma imaging for SPET applications mainly due to their excellent scintillation properties. In this work, we use Monte Carlo simulations, in order to model the optical behavior of three continuous crystal configurations. Our goal is a better understanding of the intrinsic properties of a gamma camera based on LaBr3(Ce) crystals, coupled to a position sensitive photomultiplier tube. To this aim, the spatial and energy resolutions obtainable from optimum photodetection conditions are investigated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
