Résumé

En imagerie couleur en flux d’ultrasons, le calcul des estimations d’écoulement est un problème bien connu d’un point de vue traitement de signaux. La performance de cet outil d’imagerie au niveau de la visualisation, est souvent affectée par différentes sources d’erreur telles que le manque de signaux disponibles par échantillon pour le traitement, la présence de clutter à bande large durant l’acquisition, et les déformations de signal d'écoulement qui peuvent surgir pendant la suppression des clutter à bandes larges.
