*Abstract

Current ultrasound driving systems are expensive, bulky, andhave low energy transfer rates. Thepresent invention relates to a portable, high-power ultrasound system thatcontains a low output impedance circuit that can transfer more than 95% of theenergy it generates to the ultrasound device. Due to its high efficiency, theunit can be run by a rechargeable battery pack and is thus adaptable to ahandheld unit with the potential to replace unwieldy and more expensive medicalsystems as well as RF amplifiers used in research.

Applications

Therapeutic ultrasound may be adapted as a toolto relieve arthritis, enhance wound healing, and improve rehabilitation
Drug delivery uses
Gene transfer applications.

Advantages

Portable ultrasound device suitable for ambulatory, military field use
Increased acoustical driving efficiency
Operating in the range from 1 to 10 MHz (relevant range for medical therapeutic ultrasound and HIFU systems).
