Fig. 2From: Prostate external beam radiotherapy combined with high-dose-rate brachytherapy: dose-volume parameters from deformably-registered plans correlate with late gastrointestinal complicationsRegistration evaluation using structure overlaps. Illustration of the structure overlap metric used to assess major misalignment of rectum volume (Top). Overlap of the EBRT rectum/registered HDR rectum was expressed as a percentage of the volume of the registered HDR rectum. Structure overlap results for the 118 patients after the rigid plus multi-pass DIR are provided (Bottom)Back to article page
