Abstract

L'invention concerne l'échographie médicale. Le dispositif d'échographie 10 comporte un convertisseur de balayage numérique qui reçoit les signaux d'écho détectés par le transducteur, ainsi que les signaux d'identification de l'origine de l'écho. Le convertisseur traite différemment les signaux de forte amplitude et de faible amplitude, ce qui permet d'améliorer la qualité de l'image présentée par le dispositif d'affichage 11. Application à l'échographie en temps réel.
