Abstract

L'invention concerne un dispositif d'assistance au balayage pour un système de diagnostic ultrasonore. Une sonde est montée sur une section de serrage qui effectue un mouvement itératif en arc de cercle, entraînée en rotation vers l'avant et vers l'arrière par un moteur d'entraînement, de sorte que la sonde effectue ce déplacement en arc de cercle à l'intérieur d'une section définie. Le dispositif d'assistance au balayage de la présente invention peut ainsi être monté additionnellement sur un système de diagnostic ultrasonore existant pour générer des données de volumes consécutives à intervalles fixes, afin d'améliorer la qualité d'une image tridimensionnelle.
