Abstract:
OBJECTIVETo simulate the multi-leaf collimator of Varian linear accelerator using Monte Carlo method.
METHODSThe multi-leaf collimator model was established using the DYNVMLC module of BEAMnrc and validated by comparison of Monte Carlo simulation and actual measurement results.
RESULTSThe simulation results were well consistent with the actual measurement results with a bias of less than 3%.
CONCLUSIONThe multi-leaf collimator of Varian linear accelerator can be successfully modeled using Monte Carlo method for analysis of the impact of the geometric properties of the multi-leaf collimator on the dose distribution.
