Example of data analysis workflow. (a) Representative slice containing regions of reduced absorption within enamel. Gray values correspond to linear attenuation coefficient (μ), with lighter shades representing greater X-ray absorption. The solid and dotted arrows correspond to the depth profiles in panel (c). (b) Histograms of gray values from the slice and subsample regions in panel (a). Contrast adjusted to span from −130 to 878 to capture meaningful features. The air (left) and enamel (right) subsample histograms were taken from the boxes shown in panel (a). The means of these subsamples are used to normalize the line profiles in panel (c) according to the procedure in §2.3.1. (c) Depth profiles of fractional mineral density (ρ*) corresponding to the solid and dotted paths shown in panel (a). Generated according to the procedure outlined in §2.3.3.
