Boxplots of OAR DVH index differences. The original (rpCT) and adapted plans (rpCTadapt) on the rpCT are compared to the original plan on the pCT (top panel) and to each other (bottom panel, including results of the paired Wilcoxon signed-rank test) for the 9 patients investigated in this study. Left and right eyes, optical nerves and lenses were grouped together for Pat7-9, left and right parotid glands for all patients. All dose values refer to the total dose of the SIB treatment phase for ease of interpretation. Red arrows indicate the cases with most pronounced OAR dose increase from original to adapted plan (see Discussion section)
