Abstract
Système ne nécessitant pas de longs registres à décalage. Il comprend un réseau de transducteurs 11 fournissant des signaux en réponse à la réception de signaux d'écho ultrasonores, des moyens 25, 31, 41, 45 pour démoduler les signaux formés dans les transducteurs au moyen de premier et second signaux de démolution en quadrature de phase l'un avec l'autre pour obtenir des groupes de deux signaux démodulés, des moyens 28, 34, 44, 48, pour retarder les deux signaux démodulés de chaque groupe d'un temps prédéterminé pour que tous les signaux démodulés apparaissent simultanément, des moyens 35 pour sommer les premiers signaux démodulés retardés, des moyens 50 pour sommer les seconds signaux démodulés retardés, et des moyens 51 pour former un signal résultant. Application au diagnostic médical.
