Abstract
In one embodiment, there is provided in an ultrasound wave generating apparatus a low output impedance transistor based driver circuit that has the ability to apply a drive signal at a frequency corresponding to an ultrasound transducer's resonant frequency. The low output impedance of the driver circuit allows for a substantial portion of the energy to be delivered to the ultrasound transducer and converted to ultrasound energy. The power transfer efficiency of the presented circuit allows ultrasound drivers to be powered by portable battery packs, while still delivering high ultrasound acoustic power. The ultrasound driver can provide energy in sufficient amounts making it suitable for a range of ultrasound driving application including but not limited to therapeutic low and high power clinical systems, high intensity focused ultrasound HIFU, acoustical welding, industrial inspection, and other various forms of low-to-high power acoustic devices.
