Title (EN) POWER DOPPLER IMAGING SYSTEM AND METHOD WITH IMPROVED CLUTTER SUPPERSSION
(FR) SYSTÈME ET PROCÉDÉ D'IMAGERIE DOPPLER DE PUISSANCE À ÉLIMINATION DE FOUILLIS AMÉLIORÉE
Abstract:
(EN) A method of power Doppler imaging may include receiving a plurality of temporally sequential frames of wall-filtered power Doppler signals, wherein the plurality of temporally sequential frames includes at least one previously adjusted output frame. The method may further include adjusting at least one of the plurality of temporally sequential frames to produce an adjusted output frame and generating a power Doppler image based, at least in part, on the adjusted output frame. The adjusting may involve filtering the plurality of temporally sequential frames to suppress the high spatial frequency and high temporal frequency content to produce the adjusted output frame.
(FR) L'invention concerne un procédé d'imagerie Doppler de puissance pouvant comprendre la réception d'une pluralité de trames temporellement séquentielles de signaux Doppler de puissance filtrés par paroi, la pluralité de trames temporellement séquentielles comprenant au moins une trame de sortie réglée au préalable. Le procédé peut comprendre en outre le réglage d'au moins une trame de la pluralité de trames temporellement séquentielles afin de produire une trame de sortie réglée et la génération d'une image Doppler de puissance en fonction, au moins en partie, de la trame de sortie réglée. Le réglage peut consister à filtrer la pluralité de trames temporellement séquentielles afin de supprimer la fréquence spatiale élevée et le contenu de fréquence temporelle élevé afin de produire la trame de sortie réglée.
