Point Kernel
methods:
•
Analytical solution of
primary particle transport in
the phantom
•
Use pre-calculated point
kernels from Monte Carlo to
describe the dose
deposition around a primary
photon interaction site
•
Calculate dose by
superposition of all
contributions
•
Fast superposition
methods by use of the
Collapsed Cone
approximation (any media)
or Fast Fourier Transforms
(homogeneous media only).
