Abstract

L'invention porte sur des méthodes, systèmes, et programmes informatiques de tomodensitométrie multiplexée. Selon un aspect, l'invention consiste: à irradier un objet par plusieurs faisceaux de rayons X de formes d'ondes différentes sous différents angles; à détecter les intensités des rayons X pulsés en fonction du temps; à extraire les données d'images individuelles projetées desdites intensités en fonction desdites formes d'ondes différentes, de manière à combiner les dites données d'images pour créer une image tomographique de l'objet en 3D.
