Title
(EN) ULTRASOUND COLOR FLOW DISPLAY OPTIMIZATION BY ADJUSTING DYNAMIC RANGE
(FR) OPTIMISATION D'UN AFFICHAGE COULEUR ULTRASONORE PAR REGLAGE DE LA PLAGE DYNAMIQUE
Abstract
(EN)
An ultrasound color flow imaging system is programmed to optimize display images of power and velocity by automatically adjusting thresholds and data compression by using histograms and samplings of color flow data.
(FR)
L'invention concerne un système d'imagerie couleur ultrasonore programmé pour optimiser les images affichées de puissance et de vitesse, notamment grâce à un réglage automatique des seuils et de la compression de données effectué à l'aide d'histogrammes et d'échantillonnages des données relatives aux images couleur.
