Abstract
An ultrasonic echograph is used as a profilometer for the measurement of the instantaneous blood flow rate Q(t) and the instantaneous radius variation .DELTA.r(t) and the mean radius r.sub.0 of the artery along a first excitation line A. In accordance with the invention, the profilometer is conceived to supply also Q'(t) and .DELTA.r'(t) along a second excitation line B which is situated at a distance e, of the order of magnitude of millimeters, from the first line. This collection of data enables, by calculation, determination of the elasticity or compliance .gamma.(t) of the artery and its internal pressure P(t) at the area of measurement.
