Claim:
1. An ultrasound system comprising: an ultrasound data acquisitor that includes an ultrasound probe and sequentially acquires ultrasound data corresponding to a living body; a processor that produces a plurality of ultrasound images by using the ultrasound data, sets a first ultrasound image as a reference image among the plurality of ultrasound images, sets a first region of interest (ROI) and a second ROI that is set within the first ROI on the reference image, performs motion estimation between the reference image and a second ultrasound image of the plurality of ultrasound images and between the reference image and a third ultrasound image of the plurality of ultrasound images to estimate motion of the first ROI or the second ROI, determines whether the second ROI in the second ultrasound image is outside the first ROI and whether the second ROI in the third ultrasound image is inside the first ROI, extracts the second ultrasound image as an ultrasound image needed for forming a panoramic image upon determination that the second ROI in the second ultrasound image is outside the first ROI therein, and excludes the third ultrasound image as an ultrasound image needed for forming the panoramic image upon determination that the second ROI in the second ultrasound image is within the first ROI therein; and a storage that stores the extracted second ultrasound image.
