Abstract

Osteoporosis is a common disease in USA. The consequence of this disease is reduced bone density and deteriorating bone mechanical strength. A scanning confocal acoustic scanning diagnostic (SCAD) system is developed in our lab for the characterization not only bones' quantity but quality. The results showed that SCAD determined broadband ultrasound attenuation (BUA) and ultrasound velocity (UV) are highly correlated with the bone density (R>0.72) and modulus (R>0.67). Linear regression test showed that the correlation coefficients can be further improved by combining the BUA and UV (R>0.80).
