Noninvasive Medical Diagnostics and Treatment Research at the JPL's NDEAA

FMPULThis Website describes the JPL's NDEAA noninvasive medical diagnostics and treatment activity. This activity is conducted in cooperation with:

Under the direction of Dr. Bar-Cohen, research is underway to investigate the various operative characteristics of high intensity ultrasound. To confine the wave, focused transducers are used, where high and low frequencies are modulated to take advantage of the focusing capability of high frequencies with the power that can be induced by low frequncies*. An experimental setup that was developed to harness the enabling capabilities of ultrasound was constructed and modified to allow data acquisition with the assistance of Stacey Walker. Cavitation, heating, steaming, and atomization were the phenomena that have been investigated.

* Frequency Modulated High Power Ultrasound (FMPUL), Patent No. 5,827,204
