Pencil Beam Approximation
Irradiation field decomposed in thin pencil beams Superposition of longitudinal pencil beam kernels in 2D (much faster since 2D integration) Summation of individual narrow beams Kernel creation by deconvolution of measurements (or MC) Pencil beam kernel cannot be modified locally (i.e. for inhomogeneities), does not take the changes of lateral scattering effects into consideration
