A system for performing a therapeutic procedure using focused ultrasound includes a transducer array (12) including a plurality of transducer elements (22), drive circuitry (14) coupled to the transducer elements, and a controller (16) coupled to the drive circuitry. The controller controls the drive circuitry to alternately provide sets of the transducer elements with respective drive signals. The controller also controls a phase component of the respective drive signals to provide a predetermined size, shape, and/or location of the focal zone and thereby necrose a target tissue region at the focal zone. |
