Figure 2
(a) Region of plastic rod and aluminium step wedge imaged using the dual-energy set-up. (b) Thickness of the aluminium wedge extracted by dual-energy decomposition. (c) Thickness of the plastic rod. The solid blue lines in (d) and (e) are the averaged cross-sectional thickness (mm) through each material; the dotted red lines are the actual thickness. The horizontal scale in subfigures (b)–(e) is consistent; ticks on the horizontal axes in (d) and (e) are spaced 1 mm apart. |
