Systems and methods for delivering ultrasound energy at an output power level that remains essentially constant despite variations in transducer impedance
First Claim
1. A system for delivering ultrasound energy to an ultrasound transducer having an impedance subject to variations comprising an ultrasound generator adapted and configured to be electrically coupled to the ultrasound transducer to deliver ultrasound energy, and a controller coupled to the generator, the controller being adapted and configured to execute an output power control function that delivers ultrasound energy to the ultrasound transducer at a set output frequency and at an output power level that remains essentially constant, despite variations in the impedance, based upon preprogrammed rules.

Abstract
Systems and methods deliver ultrasound energy to an ultrasound transducer having an impedance subject to variations. The systems and methods electrically couple an ultrasound generator to the ultrasound transducer to deliver ultrasound energy. The systems and methods deliver ultrasound energy to the ultrasound transducer at a set output frequency and at an output power level that remains essentially constant, despite variations in the impedance, based upon preprogrammed rules.
