Monte-Carlo simulation of the Siemens Artiste linear accelerator flat 6 MV and flattening-filter-free 7 MV beam line
Fig 5
Comparison of Monte Carlo calculated beam profiles of FFF and Flat6MV.
For two field sizes at depth of 10 cm in voxels with dimension of 5×5×5 mm3. Bars represent the uncertainty of calculation which are between 1% and 1.6%.
