Claim:
1. A method for calibrating a magnetic-resonance-guided focused-ultrasound system, comprising: (a) providing a phased array of ultrasound transducers, the array having at least one magnetic resonance (MR) tracker associated therewith at a fixed relative position with respect thereto; (b) establishing MR coordinates of the MR trackers; (c) for each of a plurality of sonication schemes, (i) creating an ultrasound focus, and (ii) establishing parameters indicative of MR coordinates of the ultrasound focus, wherein each sonication scheme is associated with a scheme-specific set of production errors; and, (d) based at least in part on the parameters, determining a geometric relationship between the ultrasound transducers and the MR trackers.
