IMRT

Monte Carlo Dose Calculation

Fast Monte Carlo codes: Virtual Source Model (VSM)

potentially efficient 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, …
