Abstract

L'invention permet de reproduire, à l'aide d'un rayonnement parasite, l'image de la répartition de densité dans un plan, en particulier dans une section corporelle d'un corps. Ce corps à examiner est soumis à l'influence d'un faisceau de Röntgen à faible section transversale. Le rayonnement parasite qui dans le corps est engendré suivant la trajectoire du rayonnement primaire, frappe des détecteurs à travers un diaphragme à ouverture en forme de fente, placé en dehors du rayonnement primaire, ce diaphragme et ces détecteurs étant placés de façon que chaque detecteur ne mesure qu'un quantum limité de rayonnement parasite engendré par le rayonnement primaire. De cette façon, à la fin d'une mesure, les signaux de sortie de détection fournissent une image qualitative de la répartition de densité dans le corps le long du faisceau de rayonnement primaire. Ensuite, le corps est déplacé sur une distance sensiblement égale à la largeur du faisceau de rayonnement primaire dans une direction perpendiculaire à la direction de ce faisceau, ce qui permet l'exploration du corps suivant des lignes. Application à l'appareillage tomographique.The invention makes it possible to reproduce, using stray radiation, the image of the density distribution in a plane, in particular in a body section of a body. This body to be examined is subjected to the influence of a Röntgen beam with small cross section. The parasitic radiation which in the body is generated along the path of the primary radiation, strikes detectors through a diaphragm with a slit-shaped aperture, placed outside the primary radiation, this diaphragm and these detectors being placed so that each detector does not measures a limited quantum of stray radiation generated by the primary radiation. In this way, at the end of a measurement, the detection output signals provide a qualitative image of the density distribution in the body along the primary radiation beam. Then, the body is moved a distance substantially equal to the width of the primary radiation beam in a direction perpendicular to the direction of this beam, which allows the exploration of the body along lines. Application to tomographic equipment.
