  1. Doses to volumes of the planning target volume (PTV), bladder and rectum for treatment plans using original kVCT, MVCT, and hybrid image sets are shown. B = bladder, R = rectum, and P = PTV. DnMVCT is the dose delivered to the absolute volume corresponding to n% of the ROI in the MVCT base plans.
