Title
(EN) MOTION COMPENSATION WITH TISSUE DENSITY RETENTION
(FR) COMPENSATION DE MOUVEMENT AVEC RÉTENTION DE DENSITÉ DU TISSU
Abstract
(EN)
A method includes reconstructing the projection data based on a reconstruction algorithm that compensates for both motion and tissue density changes of the moving organ across different motion phases, thereby generating motion and density compensated image data. A data compensator includes a reconstructor that reconstructs motion compensated image data based on an reconstruction algorithm that compensates for tissue density changes in a moving object.
(FR)
L'invention concerne un procédé qui consiste à reconstruire les données de projection d'après un algorithme de reconstruction qui compense à la fois les changements de mouvement et de densité de tissu de l'organe en mouvement dans les différentes phases de mouvement, ce qui permet de générer des données d'image à compensation de mouvement et de densité. Un compensateur de données comprend un dispositif de reconstruction qui reconstruit des données d'image à compensation de mouvement d'après un algorithme de reconstruction qui compense les changements de densité de tissu d'un objet en mouvement.
