ABSTRACT:
A method for automatically optimizing ultrasonic frequency power applied by a transducer to human tissue while the transducer is energized with ultrasonic signals from an ultrasonic signal generator. The frequency of an ultrasonic energizing signal applied by the ultrasonic signal generator to the transducer is set. The frequency of the energizing signal applied to the ultrasonic signal generator to the transducer is scanned, at reoccurring intervals, through a sequence of frequencies. The optimum level of power from the transducer is monitored as the frequency is scanned. The frequency of the ultrasonic energizing signal applied by the ultrasonic signal generator is ultimately reset, substantially at the frequency that causes the optimum level of power, until the next reoccurring interval.
