Feasibility study of SPECT system for online dosimetry imaging in boron neutron capture therapy

A single collimator version of a proposed PG-SPECT system was manufactured and experimentally tested. Combining this experimental data with Monte Carlo simulation, the viability of Ge and CdTe semiconductors detectors was calculated. It was determined that the best detector of the ones compared would be a CdTe detector of 2-3 mm, aided by the benefit of adding a Compton-suppression anti-coincidence timing detector.
