Input must now be source specific:
•
Primary dose distribution
•
Distribution of primary photon energy
spectrum
•
Distribution of 1sc photon energy
spectrum
•
Distribution of msc photon energy
spectrum
μ/ρ, μen/ρ data for the calculation of
scerma, as well as 1sc & msc
kernels, must be weighed over the
appropriate energy spectra
Implementation detail:
Primary dose distribution is fit by an
analytical expression
This allows calculations @ resolution
different than that used in the MC
simulation to derive the primary dose
distribution
