A new collimator simulation in SIMIND based on the Delta-Scattering technique
(2004) 2004 Nuclear Science Symposium, Medical Imaging Conference, Symposium on Nuclear Power Systems and the 14th International Workshop on Room Temperature Semiconductor X- and Gamma- Ray Detectors 6. p.3584-3588- Abstract
- To use conventional ray tracing methods in Monte Carlo simulation of the collimator in a scintillation camera system can be time consuming. It is however necessary to take collimator interactions into account when simulating radionuclides emitting high-energy photons that can penetrate the septa in the collimator. In this work a statistical collimator algorithm, based on the Delta-Scattering method, is evaluated using <sup>123</sup>L The evaluation is performed by comparing results from Monte Carlo simulations and measurements for a scintillation camera system, using point sources and an RSD phantom. A good agreement can be seen for both images and energy spectra.
