Summary – Evolution, not Revolution
•
Point Kernel algorithms more accurate than Pencil Kernel models
•
Modern algorithms are hybrids of deterministic numerical and Monte
Carlo methods. They can predict dose in heterogeneous tissues more
accurately.

Speed optimized MC clinically
available without large
compromise on accuracy – for
photons, electrons and protons.
Errors are stochastic.
•
In both Monte Carlo and LBTE
methods, a trade-off exists
between speed and accuracy.
