Abstract
A method for calculating fluence contributions for radiation delivery from a source to a treatment area through an aperture. The method includes defining a calculation plane located adjacent to said treatment area and a scattering plane located between the radiation source and the calculation plane. A source plane located between the radiation source and scattering plane is also defined. The method further includes ray tracing a point located on the calculation plane to the scattering plane to define a scatter strip and projecting the scatter strip from the scattering plane to the source plane to define a rectangular region. An area integration is performed on the region to determine a fluence value for the rectangular region.
