Abstract

L'invention concerne un procédé et des dispositifs pour la détermination du flux d'un volume, du profile de vélocité sanguine, des propriétés des parois artérielles d'un système de conduit tubulaire et l'identification d'une sténose et sa localisation par l'induction d'une pression artificielle ou l'envoi d'un signal d'excitation de flux (un ou plusieurs signaux) dans le vaisseau sanguin (ou dans tout autre conduit tubulaire à fluide circulant), et/ou par l'utilisation de la mesure de signaux de battements de coeur naturels et l'analyse des mouvements des parois vasculaires ou les changements du diamètre des vaisseaux.
