  • Abstract
    Objective: This work evaluates the relationship between ul- trasonic reflection and bone density from fourteen cylindrical bovine cortical bone samples (3.0-cm thick). Methods: Twenty US reflection signals per sample were acquired along the bone surface (2.0-mm step). The Integrated Reflection Coefficient (IRC) from each signal was compared to Quantitative Com- puted Tomography (QCT). Results: Seven IRC and QCT curves presented Pearson’s Correlation R-values above 0.5. For weak correlation curves, QCT and IRC showed similar trends in several segments. Conclusion: IRC was sensitive to bone density varia- tion. Level of Evidence: Experimental Study, Investigating a Diagnostic Test.
