Title

(EN) IMAGE RECONSTRUCTION INCLUDING SHIFT-VARIANT BLUR COMPENSATION
(FR) RECONSTITUTION D'IMAGE AVEC COMPENSATION DU FLOU VARIANT EN DÉCALAGE

Abstract:

(EN)An image reconstruction method comprises reconstructing an image using an iterative reconstruction method and computing a projection used in the reconstructing by summing ray increments between neighboring planes (P0, P1, P2,...) parallel with a detector face (42) with stationary incremental blurring associated with each ray increment computed based on a distance between the neighboring parallel planes. A non-stationary blurring kernel may also be convolved at a plane closest to the detector face to generate a projection incorporating shift-variant blurring.
(FR)La présente invention concerne un procédé de reconstitution d'image qui consiste à reconstituer une image à l'aide d'un procédé de reconstitution itératif et à calculer une projection utilisée dans la reconstitution en faisant la somme des incréments de rayon entre des plans voisins (P0, P1, P2,...) parallèles à une face de détecteur (42), avec un flou incrémentiel fixe associé à chaque incrément de rayon calculé en fonction de la distance entre les plans parallèles voisins. On peut également convoluer un noyau de flou non fixe dans le plan le plus proche de la face du détecteur afin de générer une projection qui intègre un flou variant en décalage.
