Abstract
Acoustic impedance transitions in human or animal bodies or other media are measured for identification and diagnostic purposes by exposing the body to acoustic energy pulses to produce echo pulses which are detected. The echo pulses are processed to indicate the relative specific acoustic impedance of the exposed body as a function of the time/distance relationship of the echo pulses relative to the medium, thereby to enable the determination of the relative extent and position of irregularities in the body, for example.
