Abstract
The present invention relates to a method and associated apparatus for improving the accuracy with which the speed of a fluid, such as a liquid, in particular blood flowing in a duct, such as a blood vessel, in particular the aorta, is measured by means of a signal emitted by a Doppler transducer (). In characteristic manner, according to the method, the Doppler transducer is associated with a programmable memory () which contains at least one correction data item for correcting the Doppler signal transmitted by the transducer () to a transducer control and computer unit (). Said computer unit () incorporates said signal correction data item in its computation (at) of each speed measurement on the basis of each signal emitted by the Doppler transducer, and it computes the speed value while taking account of said correction data item so as to provide a corrected measurement of the speed of said fluid, thereby improving its accuracy.
