Application of Monte Carlo techniques in radiation treatment planning is described in the paper. The Monte Carlo code BEAM is used to model Varian Clinic 6 MV X-ray treatment head and also a CT based HEAD phantom is simulated with DOSXYZ code using the BEAM output phase space data as the incident radiation source. Results of the simulations are presented
and compared with the Off-Axis Ratio (OAR) based method with tissue-air ratio algorithm for inhomogeneity corrections in photon beam dose calculations. The isodose lines and the cumulative dose-volume histogram of the TARGET in the two kinds of methods are in good accordance
with just slight deviation in some regions. In addition
the method of how to build a Monte Carlo geometry from the CT images of a patient is discussed in the paper.
