(FR) SYSTÈMES ET PROCÉDÉS D'IMAGERIE À AMÉLIORATION DE CONTRASTE
Abstract
(EN)
Systems and methods for visualizing microbubbles for contrast-enhanced imaging are described herein. Microbubbles may be visualized by multi-pixel spots by identifying and localizing individual microbubbles. Motion compensation may be provided for localized microbubbles or for contrast images prior to microbubble identification and localization. Users may determine the size of the multi-pixel spot by adjusting a filter, for example, adjusting a threshold value of the filter. Altering the size of the multi-pixel spot may alter the resolution. As the number of pixels increases, the resolution decreases, but the acquisition time may also decrease. As the number of pixels decreases, the resolution increases, but the acquisition time may increase.

L'invention concerne des systèmes et des procédés permettant de visualiser des microbulles pour l'imagerie à amélioration de contraste. Des microbulles peuvent être visualisées par des points multi-pixels par identification et localisation de microbulles individuelles. Une compensation de mouvement peut être fournie pour des microbulles localisées ou pour des images de contraste avant l'identification et la localisation de microbulles. Des utilisateurs peuvent déterminer la taille du point multi-pixel par réglage d'un filtre, par exemple, réglage d'une valeur de seuil du filtre. La modification de la taille du point multi-pixel peut modifier la résolution. Lorsque le nombre de pixels augmente, la résolution diminue, mais le temps d'acquisition peut également diminuer. Lorsque le nombre de pixels diminue, la résolution augmente, mais le temps d'acquisition peut augmenter.
