1. A medical system comprising:

  • a probe comprising a distal end;

    at least one probe transducer mounted on the distal end of the probe;

    a high intensity focused ultrasound (HIFU) device comprising a therapeutic array, and control circuitry, the HIFU device further comprising at least three applicator transducers mounted around the therapeutic array;

    one of the probe and applicator transducers generating acoustic energy and the other of the probe and reference transducers receiving said acoustic energy and generating electrical signals in response thereto;

    the control circuitry performing time-of-flight (TOF) calculations based on the electrical signals that indicate distances between the probe transducer and individual applicator transducers, the control circuitry performing calculations generating three-dimensional position data of the probe transducer with respect to the applicator transducers and the therapeutic array based on the TOF calculations, and the control circuitry performing local coordinate calculations for the probe transducer with respect to the therapeutic array based on the three-dimensional position data.
