1. A system for performing a therapeutic procedure in a target tissue region of a patient, comprising:

  • a transducer;

    drive circuitry coupled to the transducer for providing drive signals to the transducer such that the transducer transmits acoustic energy towards a focal zone; and

    a controller coupled to the drive circuitry, the controller configured for sequentially changing intensities of the drive signals provided by the drive circuitry from an intensity sufficient to generate microbubbles in tissue within the focal zone, to an intensity sufficient to heat the tissue within the focal zone without causing collapse of the generated microbubbles.
