Description

The purpose of this study is to validate the Monte Carlo model of the Varian Clinac IX linear accelerator (Linac). Using the BEAMnrc package, the Linac head was modelled and simulated with 3 x 3 cm2, 6 x 6 cm2, 10 x 10 cm2 and 15 x 15cm2 for 6 MV and 15 MV photons beams based on the manufacturers’ specification. For dose distribution, the scored phase-space file was used as an incident on a 60 x 60 x 24 cc virtual water phantom. The accuracy of the MC model was evaluated by comparing the central axis percentage depth dose (PDD), lateral dose profile (off axis ratio) and output factor with the beam commissioning data. The MC model dose parameter agreed measurement within 2%. This model shows the potential to be used for further dosimetric studies.
