Abstract

L'invention porte sur un procédé et un appareil pour former une image d'une cible à partir de données de retour d'écho dans un système à ultrasons qui incorpore un dispositif de traitement de données portatif disponible dans le commerce, d'un type comprenant un dispositif d'affichage, un processeur et un port E/S. Une unité de sonde contenant un transducteur ultrasonore est déplacée sur un corps devant être imagé, transmettant une énergie ultrasonore dans le corps. La sonde comprend un détecteur apte à fournir des informations concernant la position et/ou l'orientation de l'unité de sonde, qui peut être un gyroscope. Des données de retour d'écho reçues par le transducteur ultrasonore sont combinées avec la sortie de détecteur pour produire une pluralité de lignes de balayage, chacune comprenant des données d'intensité d'écho et des informations définissant la position et/ou l'orientation de la ligne de balayage. Une transformée est ensuite calculée, qui est apte à mapper les lignes de balayage sur un plan de meilleur ajustement, qui est appliqué aux lignes de balayage. Les données transformées sont mappées sur une image tramée et l'image résultante est affichée.
