GATE simulations for optimization of pinhole imaging

We validated the Monte Carlo package, GATE, for multi-pinhole gamma-ray imaging simulations using calculations and measurements. For these studies requiring large amount of photon histories, the newly designed cluster version of GATE was used. Accordingly that validated simulator allowed us then to evaluate design parameters for 123I-experiments on a prototype multi-pinhole SPECT camera for which analytical calculations were failing due to scatter of high-energy photons.
