Abstract

Le procédé d'imagerie par radiographie CT met en oeuvre un traitement sur les images pour détecter l'utilisation d'une solution saline. Lorsqu'une solution saline est détectée, il extrait un organe ou une partie d'un organe n'apparaissant pas de manière contrastée sur les images initiales, par exemple, dans le cas d'une imagerie cardiaque, la cavité droite d'un coeur. Le système d'imagerie comporte des moyens pour mettre en oeuvre ce procédé.
