1. An apparatus for applying energy within a body of a living subject, comprising:
an ultrasonic emitter configured for placement inside the body;
a housing for the ultrasonic emitter, the housing configured to place the ultrasonic emitter so that an output from the ultrasonic emitter is directed to a tissue within the body; and
a power supply connected to the ultrasonic emitter;
wherein the power supply comprises a source adapted to supply power to the ultrasonic emitter according to an input power profile having a total predetermined duration including a continuous excitation phase followed by an intermittent excitation phase, wherein the ultrasonic emitter emits ultrasonic energy into the tissue when power is supplied thereto, and wherein the input power profile comprises:
the continuous excitation phase over a first predetermined duration, during which a continuous excitation to the ultrasonic emitter is provided, which causes the ultrasonic emitter to emit ultrasonic energy into the tissue for the tissue to reach a first temperature that is equal to or higher than a necrosis temperature necessary for necrosis of the tissue, and
the intermittent excitation phase over a second predetermined duration, during which an intermittent excitation to the ultrasonic emitter is provided to cycle between on and off conditions to turn the ultrasonic emitter on and off, for the tissue to oscillate about a second temperature,
wherein the first predetermined duration and the second predetermined duration are based on the ultrasonic emitter used to emit the ultrasonic energy and based on an empirical determination of a temperature of the target tissue without monitoring the temperature of the target tissue.
