Title (EN) CLUTTER SUPPRESSION FOR SYNTHETIC APERTURE ULTRASOUND
(FR) SUPPRESSION DE FOUILLIS D'ÉCHOS POUR ULTRASONS À OUVERTURE SYNTHÉTIQUE
Abstract:
(EN) Solid-state ultrasound imaging devices, systems, and methods are provided. Some embodiments of the present disclosure are particularly directed to identifying and removing artifacts in ultrasound data due to side lobes, grating lobes, and/or other effect. In some embodiments, an ultrasound processing system (800) includes an interface operable to receive A-line signal data (602) and a focusing engine (604-612) operable to perform a focusing process on the received A-line signal data (602) to produce focused A-line signal data. The ultrasound processing system (800) also includes a coherency unit (802) operable to determine a measurement of coherency of the received A-line signal data (602). The ultrasound processing system (800) further includes an adjustment unit (804) operable to determine an adjustment to the focused A-line signal data based on the measurement of coherency, and a compensation unit (812) operable to apply the adjustment to the focused A-line signal data.
(FR) L'invention concerne des dispositifs, des systèmes et des procédés d'imagerie par ultrasons à semi-conducteurs. Certains modes de réalisation de la présente invention sont particulièrement destinés à identifier et à éliminer des artefacts dans des données d'ultrasons en raison de lobes secondaires, de lobes de périodicité et/ou d'autre effet. Dans certains modes de réalisation, un système de traitement à ultrasons (800) comprend une interface capable de recevoir des données de signal de ligne A (602) et un moteur de focalisation (604-612) capable d'exécuter un processus de focalisation sur les données de signal de ligne A reçues (602) afin de produire des données de signal de ligne A focalisées. Le système de traitement à ultrasons (800) comprend également une unité de cohérence (802) capable de déterminer une mesure de cohérence des données de signal de ligne A reçues (602). Le système de traitement à ultrasons (800) comprend en outre une unité de réglage (804) capable de déterminer un réglage des données de signal de ligne A focalisées sur la base de la mesure de cohérence, et une unité de compensation (812) capable d'appliquer ce réglage aux données de signal de ligne A focalisées.
