Monte Carlo Simulation
Fast Monte-Carlo Techniques
In the past MC was known to
be accurate …
but very time-consuming!
Approximations to increase speed:
-Multi-source model instead of
modelling full linac head
-Variance reduction techniques
-Post-processing (de-noising)
-…
However, again the danger of
approximations!
