Systems and methods for tomographic reconstruction of an image include systems and methods for producing images from k-space data. A k-space data set of an imaged object is acquired using know k-space data acquisition systems and methods. A portion of the k-space data set is sampled so as to collect some portion of the k-space data. An image is then reconstructed from the collected portion of the k-space data set according to a convex optimization model.

L'invention concerne des systèmes et procédés de reconstruction tomographique d'une image, notamment des systèmes et procédés destinés à produire des images à partir de données dans un k-espace. Un ensemble de données dans un k-espace relatives à un objet d'imagerie est acquis à l'aide de systèmes et procédés connus d'acquisition de données dans un k-espace. Une partie de l'ensemble de données du k-espace est échantillonnée de façon à recueillir une partie des données du k-espace. Une image est alors reconstruite à partir de la partie recueillie de l'ensemble de données du k-espace selon un modèle d'optimisation convexe.
