The acoustic field comprises a carrier wave and a modulated wave. The carrier wave has a plur- ality of modulated focal areas. A plurality of having known control points a spatial relation- 10 ship relative to at least one of the plurality of transducer is The ultrasonic arrays used. plur- ality of ultrasonic transducer arrays are calib- rated by using the relative position of each of -..; - the plurality of ultrasonic transducer arrays.
