Figure 4
(a) Single projection of 30 µm-thick Kapton foil showing very poor contrast. SDD = 109.3 mm, SOD = 28 mm, effective pixel size = 1.6 µm. Total number of projections 2250. Exposure time 1.5 s, setting of X-ray tube 80 kV, 100 µA, focus size of 8 µm. (b) Slice from a reconstruction performed using the Octopus package. (c) Segmentation and visualization using VGStudio is complicated owing to ray aliasing artefacts and the remains are visible at the edges of the object.
