Abstract
A technique for scanning an image field with adjacent beams of ultrasonic energy is provided in which initially transmitted beams are transmitted along beam directions at the lateral sides of the image field. Subsequent beams are alternately transmitted on either side of the initially transmitted beams and at lateral locations which converge toward the center of the image field until the full image field has been scanned. In an alternate embodiment initially transmitted beams are transmitted on one side of the center of the image field, subsequent beams diverge from the locations of the initially transmitted beams, and concluding beams laterally converge at a location on the other side of the center of the image field.
