Title (EN) HIGHLY CONSTRAINED IMAGE RECONSTRUCTION METHOD
(FR) PROCEDE DE RECONSTRUCTION D'IMAGE A CONTRAINTES ELEVEES
Abstract: front page image
(EN)An image reconstruction method includes reconstructing a composite image of a subject using a conventional reconstruction method. The composite image employs the best information available regarding the subject of the scan and this information is used to constrain the reconstruction of highly undersampled image frames. An image frame is reconstructed using limited acquired data and image quality is improved using a priori information of the subject by weighting pixel values therein by values of corresponding pixels in the composite image.
(FR)La présente invention concerne un procédé de reconstruction d'image qui consiste à reconstruire une image composite d'un sujet en utilisant un procédé de reconstruction traditionnel. L'image composite utilise les meilleures informations disponibles concernant le sujet du balayage et ces informations sont utilisées pour contraindre la reconstruction de trames d'images hautement sous-échantillonnées. Une trame d'image est reconstruite en utilisant des données acquises limitées et la qualité de l'image est améliorée en utilisant des informations a priori concernant le sujet grâce à une pondération de valeurs de pixel par des valeurs de pixels correspondants dans l'image composite.
