Abstract

L'invention concerne un procédé et un dispositif d'échographie 3D en temps réel. Le dispositif comprend une tête à ultrasons, une unité de traitement de signaux et un dispositif d'affichage. La tête à ultrasons comprend au moins un émetteur et au moins trois récepteurs, séparés dudit émetteur, dont la position par rapport à ce dernier est connue. L'unité de traitement de signaux comprend un générateur de signaux, qui génère un signal d'émission possédant n'importe quelle fonction de modulation; un corrélateur, connecté à chaque récepteur et relié au générateur de signaux; une unité de calcul, qui détermine les trajets du signal d'émission via la structure réfléchissante jusqu'aux récepteurs de chaque corrélateur; et une unité de calcul, qui détermine les coordonnées spatiales de la structure réfléchissante et à laquelle sont reliées toutes les unités de calcul déterminant lesdits trajets du signal d'émission.
