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. |
