Abstract: New and improved methodology and apparatus for non-invasive biophysical diagnosis are disclosed and comprise the ensonification of body parts with multi-frequency energy pulses in predetermined timed sequence, the detection of the resultant echo pulses, the processing of the latter to provide signals indicative of the impedance of the body part, the referencing of said signals to the biophysical cycle of the body part, and the real time display of said signals in the form of an impedance profile of said body part.
