Figure 1. Metrics of 98% target coverage, relative to the constraint of 95% of the prescription dose to each relevant structure (78/68/60/50Gy to HV/oPTV1/oPTV2/oPTV3). oPTVs were created as 5 mm expansions of the respective CTV, cropped 3 mm from the body, with a Boolean to subtract any higher-dose PTVs. Plans listed in the legend are denoted by the scan (s) and the plan (p): 78_s1_p1 = scan 1 plan 1 (initial DE plan), 78_s2_p1=scan 2 plan 1 (initial DE plan recalculated on scan 2), 78_s2_p2=scan 2 plan 2 (adapted DE plan on scan 2), etc. Abbreviations: Diff=Difference Clinical68=Clinical plan.
