  • (a) acquiring a plurality of sets of image information with an ultrasonic transducer array, said array moved substantially in an image plane between sets of image information, said image information representative of the target;

    (b) automatically determining rotational and translational components of motion in the image plane based on a plurality of comparisons of a single block of image information from a first one of said sets with a second one of said sets, said first and second ones of said sets acquired at different times; and

    (c) automatically using the components of motion determined in step (b) to register said first and second sets with respect to one another to form an extended field of view.
