Figure 3

Selected CT slices of patient 16 (N3-stage) with automatic (yellow lines) and manual (blue lines) segmentations. Large normal anatomy distortions on the left side of the patient fool the algorithm that generates inaccurate automatic segmentation (images c, d, e). Levels depicted in the different panels: a = RS and RP left; b = 2 bilaterally, 1b and RP; c and d = 3 bilaterally; e = 4 bilaterally; f = RCL left.
