ABSTRACT:
A method of diagnosing arterial stenosis from a received Doppler shifted acoustic signal from an artery during multiple heartbeats, each having systolic and diastolic phases uses pattern recognition techniques that are applied to the signal to determine the presence of turbulence during the diastolic phases which indicates stenosis. This is advantageously done by comparing the systolic and diastolic phases as part of the pattern recognition technique, large differences being indicative of a healthy artery and smaller differences being indicative of stenosis.
