Creation and Validation of Calculated Pulse Databases for Pulse Shape Analysis in the Planar Semiconductor Detectors of a Triple-Layered Compton Camera System

The position sensitive semiconductor detectors of a triple-layered Compton camera system have been characterised through collimated γ-ray scanning to aid with the subsequent development of a calculated database of charge collection signals. This database is used to perform Pulse Shape Analysis (PSA) on experimental signals in order to deliver position resolution beyond the limits of the physical voxel size. An improvement in image resolution of 3.73±0.18mm in X and 2.47±0.25mm in Y was achieved with the preliminary database comparison.
