Zusammenfassung:An ultrasonic densitometer for measuring physical properties and integrity of a skeletal member in vivo has at least one transducer (21) and electrical means for launching an ultrasound pulse, detecting receipt of the pulse and determining a parameter therefrom.The densitometer may determine transit time through the member and compare with a database value, or may determine absolute attenuation at one or more frequencies and perform a comparison based on attenuation.
