Noninvasive
Medical Diagnostics and Treatment Research at the JPL's NDEAA
This Website describes the JPL's NDEAA noninvasive
medical diagnostics and treatment activity. This activity is conducted in
cooperation with:
- Dr. Michael Kabo and Jeffery
Wang (M.D.), UCLA Medical Center
- Dr. Jack Kovach, City of Hope
- Hanspeter Loertscher,and
Pete Grandia QMI, Costa Mesa, CA
- Prof. Ajit Mal, University of California, Los Angeles
(UCLA)
- Robert Siegel (M.D.), Cedars-Sinai Medical Center
(CSMC), Los Angeles, CA
- Stacey Walker, University of Texas, Dallas
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.
