Abstract

L’invention concerne un ensemble de détection de rayons ionisants diffusés comportant : - un dispositif de filtrage (3) de rayons ionisants configuré pour filtrer spatialement les rayons ionisants en fonction de leur direction d’émission ; et - un imageur (4) assemblé en vis-à-vis avec le dispositif de filtrage (3) de sorte à recevoir les rayons ionisants filtrés par le dispositif de filtrage (3), l’imageur (4) étant configuré pour produire une image radiographique à partir des rayons ionisants filtrés par le dispositif de filtrage (3) ; le dispositif de filtrage (3) comprenant plusieurs lames, lesdites lames comprenant un matériau apte à absorber les rayons ionisants, les lames étant orientées de sorte à s’écarter d’un centre du dispositif de filtrage (3). Figure pour l’abrégé : Fig. 1The invention relates to an assembly for detecting scattered ionizing rays comprising: - a filtering device (3) for ionizing rays configured to spatially filter the ionizing rays according to their direction of emission; and - an imager (4) assembled opposite the filtering device (3) so as to receive the ionizing rays filtered by the filtering device (3), the imager (4) being configured to produce a radiographic image from the ionizing rays filtered by the filtering device (3); the filtering device (3) comprising several blades, said blades comprising a material capable of absorbing the ionizing rays, the blades being oriented so as to move away from a center of the filtering device (3).
