摘要：
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.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 unit
