Segmentation uncertainty. Left: representative example showing differences in CT/PET manual delineations (top) and 3D-Slicer segmentations (bottom). Right: This variability is quantified with the uncertainty region, defined as the difference between the observers’ agreement and observers’ union (highlighted in green). The smaller the uncertainty region is, the lower the variability among multiple contours.
