Abstract
L'invention concerne un appareil de radiodiagnostic pour réaliser des tomographies transversales. Cet apppareil est formé d'un boîtier 1 comportant une source de rayons X 4 formé d'un dispositif d'anode annulaire 6 entourant un récepteur de rayonnement 15 et situé en face d'un ensemble de cathodes 7, etc., dont le nombre correspond au nombre désiré des valeurs de mesure, et comportant des dispositifs il pour le branchement pas à pas du faisceau électronique entre au moins respectivement une cathode et l'anode, l'anode 6 et le récepteur de rayonnement 15 étant disposés de façon que trois faisceaux de rayons X 16a, b, c passent d'abord latéralement à côté du récepteur de rayonnement et tombent ensuite sur ce dernier. Application notamment aux appareils de tomographies par ordinateur.
