Abstract

An ultrasonic signal having at least two components of distinguishable waveshape or frequency content in a range from about 100 kHz to about 3 MHz is launched transdermally into the patient, through a bony member such as the patella, and received at the other side. A variety of techniques are employed for analyzing the transmission of the ultrasonic signal to assess bone condition. The velocity of ultrasound energy through the bony member also may be deduced by determining the duration of travel of the ultrasound signal through the bony member and soft tissue. Such information is then compared to a data base of prior measurements for the same patient and/or for the population at large, to determine a probability that the patient's bone condition is abnormal.
