The temporal correlation properties of ultrasonic echoes from contracting myocardium are investigated theoretically. Myocardium is modeled as a dense suspension of moving particles, with timevarying scattering amplitudes. Single scattering is assumed. Echoes from different particles are added coherently. The variance of particle velocity is proposed as an indicator of contractile performance. It is shown how this parameter may be extracted from the average correlation of pairs of echoes arising… CONTINUE READING
