Abstract

L'invention concerne un appareil d'analyse destiné à un dispositif de tomographie axiale par calculateur. Il comporte un ensemble tournant cylindrique dont la partie centrale ouverte peut recevoir une partie du corps d'un malade. L'ensemble supporte un tube à rayons X qui émet un faisceau en éventail et un ensemble de détecteurs qui reçoivent le rayonnement ayant traversé une section du corps. Un dispositif de traitement et de conditionnement de signaux, comportant au moins un amplificateur et un intégrateur par élément détecteur est également monté sur l'ensemble tournant, avec un multiplexeur et un convertisseur qui délivrent les signaux de sortie en forme numérique. Les interconnexions entre la sortie du convertisseur et le tube à rayons X d'une part et le poste de commande et de visualisation d'autre part sont assurés par des ensembles de bagues et balais. Applications au diagnostic médical.
