Abstract

La présente invention concerne un système d'imagerie ultrasonore (12) qui crée et affiche simultanément des images à partir de deux plans d'intersection ou plus en temps réel. Le système comprend une tête de sonde à ultrasons (1) et une console (2). La tête de sonde (1) a un champ de transducteur ou une combinaison d'au moins deux réseaux de transducteurs pour générer au moins deux plans d'imagerie. La console peut adresser le signal électronique (pour émettre des ondes ultrasonores) à différents réseaux de transducteurs ou à des combinaisons de transducteurs dans la même sonde et générer ainsi des images correspondantes à partir de différents plans d'imagerie que la console peut afficher simultanément. L'invention concerne également un procédé qui combine un guidage d'instrument dans le plan et hors du plan.
