Device for measuring and displaying physiological parameters of a blood flow (10) comprising a unit (300) for measuring by ultrasonic echography the speed V(t,z) of the said flow as a function of the time t and of the depth z of exploration. According to the invention, as the measurement of the speed V(t,z) is independent of the frequency of the ultrasonic wave used, the said measurement and display device comprises, at the outlet of a memory (304) for storing the values of the speed V(t,z), on the one hand a multiplexer (401) which, for a given time t, inscribes in a register i of a memory (402) the number Ni(t) of measurement samples presenting the value Vi except DELTA V, DELTA V being the discretisation step and, on the other hand, a device (403) for displaying the speed as a function of the time, such that the brilliance at the point (Vi,t) is proportional to Ni(t). …<??>Application to the echographic exploration of blood flows in the vessels. …<IMAGE>… |
