Evaluation of Shear Waves in Cortical Bone Plates Using Axial Transmission Technique

摘要

Quantitative Ultrasound (QUS) approachesrnwith the advantages of the axial transmissionrntechnique have demonstrated high efficiency inrnthe evaluation of long bones. Shear waves canrnbe useful for bone torsional strengthrncharacterization and bone medical evaluation,rnhowever, they have not been extensively reported.rnIn this study, ultrasound radiated at differentrnincident angles in thin bone plates was evaluatedrnfor the detection of shear waves using an axialrntransmission technique. Similar experimentalrnconditions were simulated and wave propagationrnwas analyzed in an isotropic bone model usingrnthe FDTD method. Experimental and simulationrnresults were compared and discussed.
