| TPET (Trent Positron Emission Tomography) is a stochastic computer simulation (using the Monte Carlo method) of a typical gamma camera (used to detect gamma-rays in nuclear medical imaging systems). It was designed to evaluate new digital pulse shape analysis (DPSA) techniques for gamma cameras with full digital capabilities. These "all-digital" systems would have enough computing resources to execute DPSA algorithms in real time for each of the phototubes in these detectors.; The Geant4 and Root packages were used to simulate the physical processes involved in gamma-ray detection and an innovative set of interpolation, Poisson, and discrete models were developed independently to create a detailed simulation of the phototube responses in these detectors.; The simulation was validated through a sensitivity analysis of the energy spectra, and through empirical comparison studies. The simulated data were found to be within the standard error of the experimental data. |
