Abstract：Objective To simulate the multi-leaf collimator of Varian linear accelerator using Monte Carlo method. Methods The multi-leaf collimator model was established using the DYNVMLC module of BEAMnrc and validated by comparison of Monte Carlo simulation and actual measurement results. Results The simulation results were well consistent with the actual measurement results with a bias of less than 3%. Conclusion The 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.
