Abstract
L'invention concerne un appareil de radiodiagnostic pour réaliser des tomographies transversales. Dans cet appareil comportant une source de rayonnement X 2, comportant un tube annulaire 15, une anode annulaire 5 et un ensemble de cathodes 18 à 22, etc, pouvant être commandées par un dispositif 29, et comportant un récepteur de rayonnement 3 formé de détecteur 30 à 35, etc., chaque détecteur peut être déplacé indépendamment des autres de manière à être amené dans le faisceau de rayons X, d'axe de symétrie 8, de manière que le faisceau de rayons X, passe d'abord devant les détecteurs et atteint seulement ensuite un certain nombre de ces derniers. Application notamment aux appareils de tomographie à calculateur.
