This work evaluates the relation between ultrasonic reflection and bone density from fourteen cylindrical bovine cortical bone samples (3.0-cm thick).
Twenty US reflection signals per sample were acquired along its surface (2.0-mm step). The Integrated Reflection Coefficient (IRC) from each signal was compared to Quantitative Computed Tomography (QCT).
Seven IRC and QCT curves presented Pearson's Correlation R-value above 0.5. For weak correlation curves, QCT and IRC have similar tendencies in several segments.
IRC was sensible to bone density variation. Levels of Evidence: Investigating a Diagnostic Test
