Figure 1: Normalized treatment plans comparison between the flattened and the flattening filter-free beams for the static intensity-modulated radiation therapy and the volumetric-modulated arc therapy plans for 6 MV beam. Head and neck, lung, and prostate cases are shown. The solid lines are the flattened beam plans and the dashed lines are the flattening filter-free beam plans
