Abstract

La présente invention concerne un procédé et un appareil de traitement de données d'imagerie multi-angle. Le procédé consiste : à exposer un objet à vérifier (120) aux rayons X à partir d'au moins deux angles afin d'obtenir des données d'imagerie multi-angle (310) ; à extraire, à partir des données d'imagerie multi-angle, des données représentant la même région dans l'objet à vérifier (120) (320) ; à reconstruire, en fonction des données extraites, une zone de section transversale (330) ; à traiter, en fonction de la descente de gradient, la zone de section transversale reconstruite afin d'obtenir une zone de section transversale reconstruite traitée ; à déterminer, en fonction de la zone de section transversale reconstruite traitée, un nombre atomique effectif et une densité caractéristique dans la région ; et à déterminer, en fonction du nombre atomique effectif déterminé et de la densité caractéristique, si la région contient un article interdit.
