Claim Text:
1. A method for mapping an ultrasound transducer comprising a plurality of transducer elements so as to improve a focus thereof, the method comprising: (a) driving the plurality of transducer elements so as to generate an ultrasound focus; (b) using acoustic radiation force imaging, measuring a displacement associated with the focus; (c) grouping the transducer elements; (d) driving a selected group of transducer elements at a variable phase while driving the other groups of transducer elements at a same constant phase, thereby varying the displacement; (e) determining a phase difference, if any, between the same constant phase and the variable phase where the displacement is maximized; and (f) if the phase difference is non-zero, adjusting a relative phase of the selected group of transducer elements based thereon.
