" Method and Appartus for Selective Cell Destruction".
Patent # 4,315,514 issued 2/16/82.
The device works on ultrasound using transducers and such. What is really
neat is that it uses an resonant frequency somewhere the inventor says
between 0.1Mhz to 4 Mhz - the medical ultrasound imager I referred to in
one of my last posts. The device uses resonant ultrasound heating effects
to destroy tumors in the body. What is done is to resonate, like a
microwave,
selected cells/tissue. Some valuable math equations are in the patent
about damping coefficients, , transmissability, and resonance.
