Abstract
a. Appareil de balayage tomographique. b. Appareil caracterisé en ce qu'il comporte une répartition de détecteurs d'énergie rayonnante, juxtaposés, répartis autour d'un axe de rotation, pour transformer l'énergie rayonnante incidente non conforme en un signal de détection correspondant, ainsi qu'un moyen pour déplacer angulairement de façon relative la source et la répartition de détecteurs autour de l'axe, pour éclairer séquentiellement divers groupes de moyens de détection et fournir une séquence de signaux de détection correspondant à la réponse en énergie rayonnante de la région située entre le chemin parcouru par la source et la répartition. c. L'invention trouve son application dans le domaine des appareils de balayage tomographiques.
