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.
