Abstract:
(EN) The present invention relates to technology for generating an ultrasound vector Doppler image using plane wave synthesis, and in a method for generating an ultrasound Doppler image, a preset number of plane waves having different incident angles are sequentially and repeatedly transmitted to a target according to a transmission sequence, reflection signals are received from the target at different locations, an ensemble frame is generated by synthesizing, among the received reflection signals, a preset number of reflection signals for each of a positive angle and a negative angle with respect to a reference direction facing the target, and a vector Doppler image generated using a plurality of ensemble frames is output.
(FR) La présente invention concerne une technologie pour générer une image Doppler vectorielle ultrasonore à l'aide de la synthèse d'ondes planes, et dans un procédé pour générer une image Doppler ultrasonore, un nombre prédéfini d'ondes planes possédant différents angles d'incidence sont émises de manière séquentielle et répétée vers une cible selon une séquence d'émission, des signaux de réflexion sont reçus à partir de la cible à différents emplacements, une trame d'ensemble est générée par synthèse, parmi les signaux de réflexion reçus, d'un nombre prédéfini de signaux de réflexion pour un angle positif et un angle négatif par rapport à une direction de référence faisant face à la cible, et une image Doppler vectorielle générée à l'aide d'une pluralité de trames d'ensemble est délivrée en sortie.
(KO) 본 발명은 평면파 합성을 이용한 초음파 벡터 도플러 영상의 생성 기술에 관한 것으로, 초음파 도플러 영상의 생성 방법은, 서로 다른 입사 각도를 갖는 미리 설정된 개수의 평면파를 송신 시퀀스(sequence)에 따라 순차적으로 반복하여 대상에 송신하고, 서로 다른 위치에서 대상으로부터 반사 신호를 수신하고, 수신된 반사 신호 중 대상에 대향하는 기준 방향을 중심으로 양(positive)의 각도 및 음(negative)의 각도 각각에 대하여 미리 설정된 개수의 반사 신호를 합성하여 앙상블(ensemble) 프레임을 생성하며, 복수 개의 앙상블 프레임을 이용하여 생성된 벡터 도플러(vector doppler) 영상을 출력한다.
