  • Diagnostic method of monitoring skeletal defect by in vivo acoustic measurement of mechanical strength using correlation and spectral analysis
    Patent number: 5143069
    Abstract: A diagnostic method for determining in vivo mechanical strength and structural integrity of hard tissues such as bones, in a non-invasive and non-dramatic manner. The method separates ultrasound energy affected by surrounding soft tissues, and thus permits unbiased determination of ultrasound parameters that represent the hard tissues. The mechanical strength of hard tissues is then determined on the basis of the ultrasound parameters, including the amount of energy propagated, the velocity of the ultrasound and the degree of dispersion together with the characteristic response of the hard tissues.
