Use of ultrasound attenuation and velocity to estimate Young's modulus in trabecular bone


Measurements were made of ultrasound transmission velocity (UTV) and attenuation (BUA) in cores of human trabecular bone. The Young's modulus and apparent density were also determined for each specimen. Analysis of the correlation between the ultrasonic parameters and the mechanical property was conducted. The highest coefficient of determination was found for a linear combination model of UTV and BUA. It is hypothesized that the improvement in the predictive ability of this model in comparison to the univariate models is due to the two ultrasonic parameters measuring different components of the trabecular bone.
