Abstract

L'invention concerne un dispositif de lecture et de traitement d'informations que contiennent des formats d'image formés par irradiations successives d'un objet dans plusieurs directions par un faisceau plat de rayonnement pénétrant. Les formats d'image formés sur une surface détectrice sont projetés sur un tube analyseur de télévision dont le dispositif de déflexion est agencé de manière à balayer l'image dans une direction perpendiculaire aux lignes de l'image, et les informations produites à chaque balayage perpendiculaire sont traitées individuellement L'invention s'applique au domaine de la tomographie.
