1. A method for determining the surface temperature of tissue adjacent to a transducer that applies energy to the tissue, comprising the steps of:

  • measuring a first temperature representative of the temperature of the transducer;

    measuring a second temperature representative of the ambient temperature of the tissue in a region that is thermally isolated from the transducer; and

    calculating the surface temperature of the tissue adjacent to the transducer from the first measured temperature and the second measured temperature.
