Abstract
A device for the measurement and display of physiological parameters of a blood flow (10), comprising a unit (300) for measuring, using ultrasonic echography, the speed V(t,z) of blood flow as a function of time t and scanning depth z. The measurement of the speed V(t,z) is independent of the frequency of the ultrasonic wave used. The device for measurment and display comprises, connected to an output of a first memory (304) for storing speed values V(t,z), a multiplexer (401) which writes, for a given instant t, the number N.sub.i (t) of measurement samples having the value V.sub.i to within .DELTA.V, .DELTA.V being the discretization step, into a register i of a second memory (402) and a device (403) for displaying the speed as a function of time, such that the brightness at the point (Vi,t) is proportional to N.sub.i (t).
