Fig. 6From: Feasibility of automated proton therapy plan adaptation for head and neck tumors using cone beam CT imagesBoxplots of OAR DVH index differences. The vCT optimized plan on the vCT is compared to the original planning scenario (original plan on pCT) for the 9 patients investigated in this study. Red arrows indicate the cases with most pronounced OAR dose increase for the adapted plan. All dose values refer to the total dose of the SIB treatment phaseBack to article page
