Description
In this study, we aimed to investigate the effect of flattened filter on dose distribution in a heterogeneous phantom using Monte Carlo simulation. The GATE Monte Carlo code was used to simulate photon beams of 6 MV in a heterogeneous phantom consisting of lung and breast tissues. The electrons accelerated by 6MV in flattened and unflattened modes were configured in Gaussian parameters. The accuracy of the simulations was validated by comparing the results with experimental measurements. All Monte Carlo simulations were performed using the HPC-Marwan high computing grid, which allowed us to simulate
several parallel jobs. The statistical uncertainty was less than 2% for all results with high correspondence between the simulations and experimental measurements. The results showed that the dose in the flattened filter-free (FFF) mode was significantly higher compared to the flattened filter (FF) mode.
