Figure 1. Relative dosimetric differences at relevant points on DVH between s-CT and p-CT def for a) OARs and b) CTV and PTV.

Gamma index passing rates are shown in Figure 2. Local gamma pass rate was above 99% in all patients when the 2mm/2% criteria and 10% threshold was applied. With 1%/1mm criteria and a threshold of 10%, the overall pass rate with global and local normalization was higher than 99% and 95%, respectively, in all cases except one patient that presented gas in abdominal cavity.
