Title
(EN) ULTRASOUND COLOR FLOW DISPLAY OPTIMIZATION BY ADJUSTMENT OF THRESHOLD USING SAMPLING
(FR) OPTIMISATION DE L'AFFICHAGE PAR CODE COULEUR ULTRASONS AVEC REGLAGE DE SEUILS AU MOYEN D'ECHANTILLONNAGES
Abstract
(EN)
An ultrasound color flow imaging system is programmed to optimize display images of power and velocity by automatically adjusting thresholds by using histograms and samplings of color flow data.
(FR)
Cette invention concerne un système d'imagerie par code couleur ultrasons qui est programmé pour optimiser les images affichées de puissance et de vitesse par réglage automatique de seuils au moyen d'histogrammes et d'échantillonnages de données en code couleur.
