The relative difference in D 95 and V 80 encompassing 95% of the treatment simulations. (Upper) Isolevels of the relative dose difference versus the nominal DVH (no dose mapping uncertainty, i.e. 〈|T e|〉 = 0 cm) that include 95% of all treatment simulation outcomes, |ΔD 95|95, as a function of the image registration uncertainty, 〈|T e|〉, and planning margin shown for the two beam models NBM and SBM. (Lower) Isolevels of the distance in relative volume at 80% of the target dose to the nominal DVH that include 95% of all outcome, |ΔV 80|95, for the rectum.
