SECT (HU-ρ) curve for the calibration phantom at 50 kVp in black and at 90 kVp in red. The vertical dotted (50 kVp) and dashed lines (90 kVp) represent the selected boundaries between media in a segmentation scheme with seven materials (I to VII). The roman numerals I-VII indicate the materials: air, AP6, Solid Water, B200, CB2–30%, CB2–50% and SB3. Other segmentation schemes with a different number of intervals are possible. The dots represent the mean HU value of each material
