Portable Low Output Impedance Ultrasound System for Therapeutics Uses & Drug Delivery

详细技术说明

The invention describes a portable and rechargeable high power ultrasound system with a very low output impedance amplifier circuit.

*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).
