In recent years, doctors have used ultrasound to effectively treat joint pain from arthritis and other ailments without the use of drugs. The drawback to these treatments, however, is that they can only be administered in a doctor's office or clinic, since the ultrasound devices currently used are bulky and expensive. Enter George K. Lewis, a biomedical engineering graduate student at Cornell University whose research is supported by the National Science Foundation. Lewis has developed a portable ultrasound device about the size of an iPod that can provide pain relief for several hours without being tethered to a doctor's office.
