Abstract
An ultrasound imaging system acquires a sequence of partially overlapping image frames, and stores data corresponding to the image frames in a image frame buffer. The relative spatial positions of the image frames are determined by a correlator, and the resulting spatial position data are then stored in an extended image memory and a history buffer along with data corresponding to the image frames. The data stored in the extended image memory and the history buffer can then be used to generate a panoramic image, which is displayed by the imaging system. Significantly, the data corresponding to the image frames are retained in the image frame buffer after the panoramic image has been displayed so that specific image frames can be excluded from the data corresponding to the panoramic image to either edit defective image frames from the panoramic display or to trim the boundaries of the panoramic display.
