(a) Optical microscopy images of a 5 µm thick human bone section taken in the dense cortical part of the femoral midshaft of a healthy human female; (b) X-ray transmission scan of the region indicated by the box in (a), obtained using a 1 µm diameter beam with 1 µm scan steps in both directions; (c) image of the SAXS intensity (arbitrary units) according to equation (1) using the same scan parameters; (d) magnified region of the box in (c); (e, f) individual two-dimensional SAXS patterns from (d); (g) image of the mineral platelet thickness T (in nm) using the same scan parameters as in (b) and (c); (h) azimuthally averaged intensity profiles from the scattering patterns (e) and (f). The red dotted line shows a −4 slope in the double-logarithmic representation in accordance with Porod's law. |
