 The conventional ultrasonic bone densitometry systems(quantitative ultrasound:QUS)are now popular for the initial screening of osteoporosis. These systems can give us velocity(SOS)and broadband attenuation(BUA)of ultrasonic waves, which propagated in the heel. This paper describes the physical meaning of these parameters and introduces the idea of standardization, s-SOS and s-BUA. In addition, new QUS techniques for the further investigation of bone quality are also introduced. These techniques, two wave phenomenon and Axial Transmission(AT)can induce the individual properties of cortical and cancellous bones by the ultrasonic measurements.
