FIELD: medical equipment.
SUBSTANCE: invention relates to medical equipment, namely to diagnostic ultrasound systems. Diagnostic ultrasound system for measuring regurgitant flow comprises an ultrasound probe, image processor, ripple wall filter, responsive to received echoes, having a response characteristic extending between zero and the Nyquist limits of ±1, at that response characteristic has only one maximum in the range from 1/2 to 2/3 of Nyquist, response characteristic gradually extends from zero to maximum, system also comprises a Doppler processor, flow quantification processor and display device.
EFFECT: invention allows improving measurement accuracy.
