1. A system for providing ultrasound energy having a stable power output, the system comprising:

  • an ultrasound transducer that emits ultrasound energy at a specific frequency and at a predetermined power level;

    a power sensor that monitors a power level of the ultrasound energy over time;

    a temperature sensor that monitors a temperature of the ultrasound transducer over time; and

    an ultrasound controller in communication with the ultrasound transducer, the power sensor, and the temperature sensor,the power sensor communicates the power level to the ultrasound controller,the temperature sensor communicates the temperature of the ultrasound transducer to the ultrasound controller,the ultrasound controller corrects a frequency of the ultrasound energy to the specific frequency upon the power level deviating from the predetermined power level,the ultrasound controller corrects the frequency of the ultrasound energy to the specific frequency upon a change in the temperature of the ultrasound transducer, wherein the change of temperature is outside a predetermined temperature range, andthe ultrasound controller thereby maximizes efficiency of the ultrasound transducer emitting the ultrasound energy.
