Micro-CT Fig differences

(a) Plots of skeletal volume trends within the x-y cross section of a 12x12x12 mm³ ROI as function of distance along the z-axis of the ROI for both 20 micrometer and 10 micrometer micro-CT data. (b) Representative slice (at 4.3 mm) from sample PorlutC comparing the 20 micrometer to 10 micrometer micro-CT data (left hand figures) and segmented skeleton in both (right hand figures). White scale bar = 6mm. (c) Difference between the 20 micrometer and 10 micrometer data trends plotted in part A highlighting the very small variability within the porosity trends with no consistent trend towards an under- or over- estimate of porosity at one given resolution.
