Abstract
An ultrasonic instrument employs a digital architecture to provide improved stability to sound speed measurements of human bone in vivo. A digitization of the received ultrasonic signal allows numerical analyses to be applied in determining precise arrival time of the waveform. The microprocessor may initiate the ultrasonic signal transmission and detect its arrival and may control the strength of the transmitted signal and the amplification of the received signal to optimize the signal path.
