چکیده :
Monte Carlo (MC) methods are considered as the most accurate dose calculation method and a gold standard for dose assessment in radiation therapy. The purpose of this study is to fully simulate a benchmarked Artiste head and the Siemens 160 multileaf collimator (MLC) by MCNPX 2.6 Monte Carlo code. A comparison between MC-based and TPS-based dose maps was made for beams of two typical plans and it was shown that the 3D gamma passing rates with clinical criteria of 3%/3mm are acceptable. Therefore, the provided model has sufficient accuracy and reasonable computation time to be used for verification of complicated plans.
