    an array positioned in communication with the ultrasound probe;

    first means for determining the position of the ultrasound probe relatively to the array;

    second means for determining the position of the body part relative to the array; and

    means for translating the position of the ultrasound probe as determined by the first means into a coordinate system corresponding to the position of the body part as determined by the second means;

    means for scanning the body part to create scanned images thereof; and

    means, responsive to the scanning means, for generating a scanned image of the body part corresponding to the determined position of the ultrasound probe relative to the body part whereby the ultrasound image of the body part corresponds to and may be compared with the scanned image of the body part.
