Abstract

Monte Carlo treatment planning requires accurate beam information as input to generate accurate dose distributions. The phase space data of a clinical photon beam can be obtained by simulating the accelerator treatment head using a Monte Carlo code, such as BEAM [1–2]. The simulated phase space data (or the subsequently derived multiple source model) can be used for Monte Carlo treatment planning dose calculation [3]. However, it is not practical to simulate every individual clinical photon beam in a routine clinic [4–5].
