Abstract

L'invention concerne un appareil de radiologie sans film et le procédé d'utilisation dudit appareil. Cet appareil comprend une source de rayons X (1) dont les rayons (x) passent à travers un sujet (2) tel qu'un animal, un homme, ou bien un bagage placé dans le scanner d'un dispositif de sécurité d'aéroport, pour entrer dans un écran d'intensification fluorescent (3). Un miroir de verre (6), pourvu d'un recouvrement d'aluminium et d'une couche dorsale de plomb, ne reflète, en direction d'au moins une caméra vidéo (7), que la composante visible des rayons qui traversent l'écran fluorescent. Les signaux vidéo émis par la caméra vidéo (7) sont dirigés vers des circuits de capture d'image vidéo (8) fonctionnant en association avec un ordinateur (9) équipé d'un logiciel de traitement et d'amélioration des images.
