Abstract

L'invention concerne un système (10) d'imagerie ultrasonique portatif, comprenant une tête de balayage (12) couplée par un câble (16) à un processeur (14) de données et une unité d'affichage portatifs, alimentés par batterie. Le boîtier (12) de la tête de balayage loge une pluralité de transducteurs ultrasoniques et les circuits associés, en particulier les circuits de synchronisation des impulsions utilisés dans le mode transmission pour transmettre des impulsions ultrasoniques et les circuits formant les faisceaux utilisés dans le mode réception pour focaliser dynamiquement les signaux ultrasoniques réfléchis arrivant de la zone d'intérêt à reproduire en images.
