Monte Carlo Dose Calculation
Fast Monte Carlo codes:
Virtual Source Model (VSM)
efficient (approximate) modelling
of effects of beam modulating
elements (transmission maps etc.)
In the patient: variance reduction
techniques, history repetition;
optimized for voxel geometries;
optimized for energy range typical
in RT and material compositions
in human tissue, …
