Abstract

Détecteur de rayons X comportant de nombreux éléments de détection et utilisé dans un dispositif pour la tomographie par voie d'ordinateur dans lequel, à l'aide d'un faisceau divergent à faible section transversale, un corps à examiner est irradié suivant différentes directions. On mesure le rayonnement qui localement a pu traverser le corps à examiner et sur la base des résultats de mesure ainsi obtenus on calcule la répartition de la densité dans la section corporelle irradiée. Au cours de l'examen, le faisceau de rayons X et le détecteur tournent en synchronisme autour du corps. Dans un boîtier étanche au gaz, le détecteur comporte plusieurs électrodes quasi parallèles et élaborées sur une plaque de support Pour éviter que des vibrations engendrées dans l'appareil n'influencent les signaux de sortie du détecteur, lesdites plaques de support sont formées par un matériau absorbant fortement les vibrations. Application à l'appareillage radioscopique utilisé en médecine.An X-ray detector having many detection elements and used in a device for computer tomography in which, by means of a diverging beam of small cross section, a body to be examined is irradiated in different directions. The radiation which may have passed through the body to be examined locally is measured and on the basis of the measurement results thus obtained, the density distribution in the irradiated body section is calculated. During the examination, the X-ray beam and the detector rotate in synchronism around the body. In a gas-tight housing, the detector comprises several quasi-parallel electrodes and formed on a support plate To prevent vibrations generated in the device influencing the output signals of the detector, said support plates are formed by a material strongly absorbing vibrations. Application to the fluoroscopic apparatus used in medicine.
