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
