Microfibril Orientation Dominates the Microelastic Properties of Human Bone Tissue at the Lamellar Length Scale
Figure 3
Comparison between local elastic properties and mineral ultrastructural characteristics.
From top to bottom: A acoustic impedance (Z), B degree of mineralization of bone (DMB), C T-parameter linked to the mineral thickness, D ISAXS related to changes in the lamellar orientation (the results are illustrated for ost1). For each investigated parameter, the solid line represents its variations along a radial profile going from the Haversian canal to the outer lamellae. The dashed line represents the corresponding smoothed profile after averaging the values between adjacent peaks. The coefficient of variation of the root-mean-square error CV(RMSE) provides a measure of the relative amplitude fluctuations of the measured values around the averaged profile curves.
