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
