Comparing dose conformity to the target (CN) of the plans acquired by quadratic min. [solid (-)], TV min. [dashed (- -)], and reweighted TV min. [dashed-dotted (-.)] in (a) Prostate1, (b) Prostate2, (c) Lung, (d) HN1, (e-1) HN2 data for PTV66, and (e-2) HN2 data for PTV54, respectively. To achieve a similar CN, the reweighted TV min. required 10–15 fewer segments than TV min. and 30–35 fewer segments than quadratic min. based plans.
