95 (CTV) and V
80 (OARs), i.e. ∆D
95 and ∆V
80, due to dose mapping uncertainty, for all ten instances of the patient, as a result of the image registration uncertainties 〈|T
|〉 equal to 0.2 and 0.4 cm. The leftmost column shows the distribution for dose distributions using the NBM and no planning margin, the middle column using a planning margin m and the right column the result for the dose distribution using the SBM.
