Abstract

Dans un dispositif pour définir des différences locales en absorption de rayonnement à l'intérieur d'un corps, on utilise un faisceau d'électrons enregistreur qui procède à une exploration suivant la largeur du corps. La mesure directe est toujours possible du fait que depuis chaque face d'impact du faisceau d'électrons, un collimateur sélectionne un faisceau élémentaire dans le faisceau de Röntgen. Du fait d'utiliser un faisceau divergent et un détecteur frappé par le rayonnement, on peut effectuer la mesure sans mouvement mécanique au moins pour une seule section corporelle. Application à l'appareillage par voie de tomographie.
