Abstract:
(EN) Disclosed are a weighted interpolation method and an ultrasonic diagnostic apparatus using same. Provided is an ultrasonic diagnostic apparatus comprising a probe for transmitting an ultrasonic signal to an object and receiving an ultrasonic echo signal reflected from the object, which includes a sub-aperture for transceiving the ultrasonic signal and the ultrasonic echo signal; an ultrasonic diagnostic unit for generating the ultrasonic signal, applying a predetermined weight to the ultrasonic echo signal and focusing the ultrasonic echo signal to form an intermediate focused signal; and an image processing unit for forming an image based on the intermediate focused signal and outputting the image through a display unit. The ultrasonic diagnostic unit includes an interpolation portion for generating an interpolation signal for interpolating the intermediate focused signal using a correlation analysis function. According to an embodiment of the present invention, the received focused signal formed by focusing the ultrasonic echo signal received from the sub-aperture of the probe is interpolated to solve problems of discontinuity of sub-apertures, and a clutter level is lowered to improve a contrast resolution of an image, improving the quality of the image as a result.
(FR) La présente invention se rapporte à un procédé d'interpolation pondérée et un appareil de diagnostic à ultrasons l'utilisant. L'invention concerne un appareil de diagnostic à ultrasons comprenant une sonde qui permet de transmettre un signal ultrasonore à un objet et de recevoir un signal d'écho ultrasonore réfléchi par l'objet, qui comprend une sous-ouverture permettant d'émettre et de recevoir le signal ultrasonore et le signal d'écho ultrasonore ; une unité de diagnostic ultrasonore qui permet de générer le signal ultrasonore, par l'application d'un poids prédéterminé au signal d'écho ultrasonore et en focalisant le signal d'écho ultrasonore pour former un signal focalisé intermédiaire ; et une unité de traitement d'image qui permet de former une image sur la base du signal focalisé intermédiaire et en produisant l'image en sortie à travers une unité d'affichage. L'unité de diagnostic ultrasonore comprend une partie d'interpolation destinée à générer un signal d'interpolation afin d'interpoler le signal focalisé intermédiaire à l'aide d'une fonction d'analyse de corrélation. Selon un mode de réalisation de la présente invention, le signal focalisé reçu formé par la focalisation du signal d'écho ultrasonore reçu à partir de la sous-ouverture de la sonde est interpolé de manière à résoudre les problèmes de discontinuité de sous-ouvertures, et un niveau de fouillis est abaissé afin d'améliorer une résolution de contraste d'une image, améliorant ainsi la qualité de l'image.
(KO) 가중치 보간 방법 및 이를 이용한 초음파 진단장치를 개시한다. 대상체로 초음파 신호를 송신하고 상기 대상체로부터 반사되는 초음파 에코 신호를 수신하되, 상기 초음파 신호 및 상기 초음파 에코 신호를 송수신하기 위한 서브애퍼처(Sub-Aperture)를 포함하는 프로브(Probe); 상기 초음파 신호를 생성하고, 상기 초음파 에코 신호에 소정의 가중치(Weight)를 적용한 후 집속하여 중간 집속신호를 형성하는 초음파 진단부; 및 상기 중간 집속신호에 기초하여 영상을 형성하며, 상기 영상을 디스플레이부를 통해 출력되도록 하는 영상 처리부를 포함하되, 상기 초음파 진단부는 상기 중간 집속신호를 보간하기 위한 보간신호를 상관분석 함수를 이용하여 생성하는 보간부를 포함하는 것을 특징으로 하는 초음파 진단 장치를 제공한다. 본 실시예에 의하면, 프로브의 서브애퍼처로부터 수신된 초음파 에코 신호를 집속하여 형성된 수신 집속 신호를 보간하여 서브애퍼처 간의 불연속을 해결하고, 클러터 레벨(Clutter level)을 낮춰 영상의 대조 능력(Contrast Resolution)를 향상시키고, 결과적으로 이미지의 퀄리티(quality)을 향상시킬 수 있는 효과가 있다.
