Abstract
An echograph of the type involving signal processing in the time domain with correlation-interpolation of the echographic signals is adapted to measure radial displacement velocities of the walls of an artery. A frame is scanned with a period T of a few ms at a rate of one excitation per line, and the correlations-interpolations are performed between collinear excitation lines shifted by the period T (52), enabling velocity values V(x,z,t) to be obtained for storage in a first memory (55) and amplitude values A(x,z,t) for storage in a second memory (57). These values are subsequently processed (60) in order to deduce dilatation and compression curves therefrom.
