Means (mean ∆S) and 6σ-intervals (6σ ∆S) of the surface deviation between reference 3D-scan and direct segmentation results. Each of the five red and blue lines in each diagram reflect the CT with corresponding slice thickness of 0.4 mm, 0.6 mm, 1.5 mm, 3.0 mm and 5.0 mm. A detailed analysis for the segmentations highlighted with numbers is provided in Figure 13-Figure 16 of Appendix A
