Abstract

Un procédé (30) de traitement d'une image radioscopique comprend les étapes consistant à produire (32) un modèle de prédiction de rémanence, balayer (34) un objet à une première dose de rayonnement à l'aide d'un système d'imagerie comprenant au moins une source de rayonnement et au moins une matrice de détection, et mettre périodiquement à jour (36) le modèle de prédiction de rémanence au cours du balayage afin de produire au moins une image radioscopique de l'objet.
