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 has been developed in our lab for characterization of not only bones´ quantity but also 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 tests showed that the correlation coefficients can be further improved by combining the BUA and UV (R>0.80).
