Title (EN) SYSTEM AND METHOD FOR ECG-TRIGGERED RETROSPECTIVE COLOR FLOW ULTRASOUND IMAGING
(FR) SYSTEME ET PROCEDE D'IMAGERIE ECHOGRAPHIQUE COULEUR RETROSPECTIVE ACTIVEE PAR ECG
Abstract:
(EN) A method and a device for producing an ECG-triggered retrospective color-flow ultrasound image comprises generating ultrasound, transmitting the ultrasound into a subject at a first location, wherein a first reference point of an ECG signal taken from the subject triggers the ultrasound transmission, receiving ultrasound reflected from the subject at the first location, transmitting the ultrasound into the subject at a second location, wherein a second reference point of an ECG signal taken from the subject triggers the ultrasound transmission receiving ultrasound reflected from the subject at the second location, processing the received ultrasound to form ultrasound color traces, and reconstructing the ultrasound color traces to form the ultrasound image.
(FR) L'invention concerne un procédé d'imagerie échographique couleur rétrospective activée par ECG. Ce procédé consiste à générer des ultrasons, à émettre ces ultrasons dans un premier site dans le sujet, l'émission d'ultrasons étant activée par un premier point de référence d'un signal ECG enregistré chez le sujet, à recevoir les ultrasons renvoyés à partir du premier site du sujet, à émettre des ultrasons dans un second site dans le sujet, l'émission d'ultrasons étant activée par un second point de référence d'un signal ECG enregistré chez le sujet, à recevoir les ultrasons renvoyés à partir du second site du sujet, à traiter les ultrasons reçus afin de former des traces couleurs échographiques, et à reconstruire les traces de couleur échographiques pour former l'image échographique.
