ABSTRACT:
A device for measuring one of the transverse components V.sub.x of the speed of moving organs and blood flows by means of ultrasonic echography, the axial component V.sub.z, oriented parallel to the axis O.sub.z of the ultrasonic beam, being measured by a first intercorrelation circuit (51.sub.z) which operates with a sampling step .DELTA.T and which supplies, on the basis of two successive echographic lines shifted through k.DELTA.T, (k=-I, -I+1, . . . , I), 2I+1 correlation function values according to z, a first maximum-value searching circuit (53.sub.z) which supplies the value I.sub.o of k which corresponds to the largest value of said correlation functions according to z. The device includes:
