Multiple-focus ultrasound phased-array pattern synthesis: optimal driving-signal distributions for hyperthermia

A method for computing array element amplitude and phase distributions for direct synthesis of multiple-focus field patterns using ultrasonic phased arrays is shown to be capable of producing desired field levels at a set of control points in the treatment volume. The complex pressure at any of thes...
