Abstract
L'invention concerne un système et un procédé permettant d'améliorer la qualité d'images ultrasonores. Le système comprend un processeur étant configuré pour subdiviser l'image ultrasonore, pour déterminer un facteur de déconvolution pour l'image ultrasonore et pour appliquer le facteur de déconvolution à l'image ultrasonore subdivisée, ce qui permet de fournir une image restaurée.
