1. A method for providing conformal thermal treatment to diseased tissue in a target volume, comprising:

  • inserting at least a portion of a multi-element ultrasonic thermal applicator into the volume containing the diseased tissue;

    driving a plurality of the elements of the multi-element ultrasonic thermal applicator with respective driving signals having respective frequencies and amplitudes;

    independently controlling the driving frequency for at least one element of the multi-element ultrasonic thermal applicator;

    independently controlling the driving amplitude for at least one element of the multi-element ultrasonic thermal applicator;

    scanning the target volume with an ultrasonic beam resulting from driving the plurality of elements of the multi-element ultrasonic thermal applicator; and

    monitoring a thermal effect of the treatment in a region including the diseased tissue.
