Abstract
A method for altering the lateral dimension of the focal zone produced by an integral ultrasonic lens system. The method comprises the steps of removing a volume of lens material from the integral lens system so as to define two separate and distinct remainder volumes on each side of the removed volume. The remainder volumes are then laterally or rotationally displaced relative each other to alter the lateral dimension of the focal zone produced by the integral lens or to produce a discrete focal zone for each of the remaining lens volumes.
