Title (EN) VISUALISING THREE-DIMENSIONAL IMAGES OF VARIABLE OBJECTS
(FR) VISUALISATION D'IMAGES TRIDIMENSIONNELLES D'OBJETS VARIABLES
Abstract:
(EN) A method of reducing the effects of deformation movement of an examined body in the computing of a 3D cone beam CT image of the examined body, the method including the steps of: (a) acquiring a series of projections around a patient wherein the projections can include the angular rotation of the examined body relative to a gravitational reference frame; (b) sorting the projections into a series of angularly correlated bins, for different angular rotations of the examined body; (c) constructing a deformation blurred image from the projections as an initial prior image; and (d) utilising the initial prior image and the projections for an angular bin to optimise a digital tomosynthesis reconstruction of the projections of at least one angular bin.
(FR) La présente invention concerne un procédé de réduction des effets de mouvement de déformation d'un corps examiné dans le calcul d'une image de tomodensitométrie à faisceau conique tridimensionnel du corps examiné, ledit procédé comprenant les étapes consistant à : (a) acquérir une série de projections autour d'un patient, lesdites projections pouvant comprendre la rotation angulaire du corps examiné par rapport à une structure gravitationnelle de référence ; (b) trier les projections dans une série de secteurs corrélés angulairement, pour différentes rotations angulaires du corps examiné ; (c) construire une image floue de déformation à partir des projections en tant qu'image antérieure initiale ; et (d) utiliser l'image antérieure initiale et les projections pour un secteur angulaire pour optimiser une reconstruction numérique en tomosynthèse des projections d'au moins un secteur angulaire.
