Title
(EN) SYSTEM AND METHOD FOR ARTIFACT REDUCTION IN AN IMAGE
(FR) SYSTÈME ET PROCÉDÉ DE RÉDUCTION D'ARTÉFACTS DANS UNE IMAGE
Abstract
(EN)
Selected artifacts, which may be based on distortions or selected attenuation features, may be reduced or removed from a reconstructed image. Various artifacts may occur due to the presence of a metal object in a field of view. The metal object may be identified and removed from a data that is used to generate a reconstruction.
(FR)
L'invention permet de réduire ou d'éliminer des artéfacts sélectionnés, qui peuvent être basés sur des distorsions ou des caractéristiques d'atténuation sélectionnées, d'une image reconstruite. Divers artefacts peuvent apparaître en raison de la présence d'un objet métallique dans un champ de vision. L'objet métallique peut être identifié et retiré de données servant à générer une reconstruction.
