Monte Carlo Simulation

• More efficient by performing the simulation of patient-independent structures and to store what is called

a phase-space file → can be reused as often as necessary

• Variance reduction techniques (low interest particles like electrons created from photon interactions in treatment head are eliminated with a given probability) help to speed up • Parallelization via GPU improves speed as well • Example codes are: EGS, ITS, PEREGRINE (first FDA approved), VMC (Monaco, PrecisePlan, iPlan) , MCNP, PENELOPE, GEANT4
