"Groundbreaking" Ultrasound device invented by PhD student

Ultrasound machines can cost $20,000 or more and weigh 30 pounds, but not George K. Lewis's ultrasound device. Lewis's portable therapeutic ultrasound machine cost him about $150 to make -- 80 percent of which was spent on the battery -- it fits in the palm of his hand, and it can help treat cancer and relieve arthritis... among other things.

A third-year PhD National Science fellow at Cornell University in biomedical engineering, Lewis authored a paper in the Journal Review of Scientific Instruments that explains...

Groundbreaking, inexpensive, pocket-sized ultrasound device can help treat cancer, relieve arthritis.

A prototype of a therapeutic ultrasound device, developed by a Cornell graduate student, fits in the palm of a hand, is battery-powered and packs enough punch to stabilize a gunshot wound or deliver drugs to brain cancer patients. It is wired to a ceramic probe, called a transducer, and it creates sound waves so strong they instantly cause water to bubble, spray and turn into steam.

Tinkering in his Olin Hall lab, George K. Lewis, a third-year Ph.D. student in biomedical engineering...
