Dose-volume histograms (DVHs) of target volumes. Dose-volume histograms (DVHs) of a primary target volume from primary plans (a), boost target volume from boost plans (b), primary target volume from sum plans (c) and boost target volume from sum plans (d) calculated from a total of 20 volumetric modulated arc therapy (VMAT) plans for prostate cancer are shown. The average DVHs of original VMAT plans are plotted with solid black lines while those of the shifted VMAT plans are plotted with dashed black lines. Every single DVHs of original VMAT plans are plotted with solid gray lines while those of the shifted VMAT plans are plotted with dashed gray lines
