Fig. 5From: Evaluation of plan robustness on the dosimetry of volumetric arc radiotherapy (VMAT) with set-up uncertainty in Nasopharyngeal carcinoma (NPC) radiotherapyA sample of dose-volume histograms (DVHs) of OARs was compared for 1 treatment plan and 5 U-plans. The DVH curve in the solid line represented the treatment plan. The DVH curves in the dashed line represented 5 U-plans.
