  1. Mean and Standard Deviations parameters (in percentage) of the differential DVH for AAA-Acuros11 and Acuros10-Acuros11 difference plans. Both parameters are recorded as Mean ± SD and range for lung, PTV and their sub-structures. For lung contours, both DIBH and FB modes are reported, while for PTV contours only DIBH is shown.
