Abstract:
1. A method of providing ultrasound energy having a stable power output, the method comprising: emitting ultrasound energy from an ultrasound transducer at a specific frequency and at a predetermined power level; monitoring a power level of the ultrasound energy over a time; communicating the power level to a controller; correcting a frequency of the ultrasound energy to the specific frequency upon the power level deviating for the predetermined, power level; monitoring a temperature of the ultrasound transducer over the time of the emitting ultrasound energy; communicating the temperature of the ultrasound transducer to the controller; and correcting 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; thereby maximizing efficiency of the ultrasound transducer emitting the ultrasound energy.
