Low-resolution scans and 3D reconstruction of the nail. (a) On the left, the exact position of each virtual cross section in the nail shown on the right. (b) Histogram quantifying percentages of metal, corrosion and soil per each slice shown in a. (c) 3D reconstruction of the nail and segmentation of different layers: yellow—soil, red—corrosion layer, blue—metal; on the right, pie chart indicating the total percentages composition resulted by imaging segmentation. (d) Sagittal section of the 3D reconstruction showing the internal region of one half of the nail.
