Abstract

L'invention concerne un procédé pour réaliser des tomographies à l'aide de rayons X ou de rayons pénétrants analogues. L'appareil pour la mise en oeuvre du procédé comporte un dispositif à plusieurs sources de rayonnement (tubes à rayons X 28 à 31) séparées les unes des autres en étant disposées suivant une rangée et en pouvant être branchées successivement par application de tensions adéquates aux anodes 32 à 35, aux cathodes 48 à 51 et aux grilles de commande 44 à 47. Application notamment aux appareils de radiodiagnostic pour la réalisation de tomographies par ordinateur.
