Abstract

L'invention concerne un procédé et un système d'acquisition de données d'images d'un sujet. Les données d'images peuvent être collectées par un système d'imagerie possédant un détecteur capable de se déplacer par rapport au sujet. Un agent de contraste peut être injecté dans le corps du sujet et des données d'images peuvent être acquises par l'agent de contraste dans différentes phases du sujet. Un modèle volumétrique de phases multiples peut être reconstruit selon des techniques de reconstruction sélectionnées.
