摘要

A Monte Carlo optical code for the optimisation of scintillation gamma cameras based on a single scintillator coupled to arrays of Silicon Photodiodes (PDs) or Silicon Drift Detectors (SDDs) have been developed. The simulator allows to calculate the expected gain (e-/keV), position resolution and energy resolution of the gamma detector for different geometries and boundary conditions at the crystal interfaces. A validation of the algorithm has been carried out by comparing the results of the simulations with the corresponding experimental results obtained on existing prototypes of detectors recently developed. An example of application of the proposed code in the study of a small scintillation camera is also reported.
