Abstract

A method includes acquiring vibrational cardiac data from an array of N transducers wherein the transducers are coupled to a human. A master replica is selected from a segment of the vibrational cardiac data. The master replica is correlated with the segment to obtain a plurality of local maxima. Vibrational cardiac data that were emitted during a diastolic interval are extracted from each heart cycle with the aid of the plurality of local maxima. A two-dimensional space-time frequency power spectrum is processed for Equivalent Rectangular Bandwidth, which provides estimates of the energy produced by turbulent blood flow through a coronary stenosis.
