There are three ways to determine the spectrum of a clinical photon beam: direct measurement, modelling the source and reconstruction from ion-chamber measurements. We focus on reconstruction because the necessary equipment is readily available and it provides independent confirmation of source models for a given machine. Reconstruction methods involve(More)
The goal of radiation therapy is to destroy the tumor with no side-effects. The recently developed technique of intensity modulated radiation therapy (IMRT) uses spatially nonuniform intensities. While this allows more flexibility and better treatments, it also increases the search space and hence requires optimization. We demonstrate the success of linear(More)
