[ 1 ] - Characterization of low, medium and high energy collimators for common isotopes in nuclear medicine: A Monte Carlo study

Introduction:In an ideal parallel-hole collimator, thickness of septal material should be sufficient to stop more than 95% of incident photons. However, some photons pass the septa without interaction or experience scattering before they reach the detector. In this study, we determined different contribution of collimator responses consist of geometrical response, septal penetr...
