Cellphone becomes medical image device

DAVIS, Calif. (UPI) -- U.S. researchers say they've transformed aniPhone into a high-quality medical imaging device that could transformmedicine in developing countries.

Using only inexpensive materials, researchers at the University ofCalifornia, Davis, have modified smartphones to perform detailedmicroscopy, a release from the Optical Society of America said Monday.

Kaiqin Chu, a postdoctoral researcher in optics, inserted a $40 balllens -- a finely ground glass sphere that acts as a low-poweredmagnifying glass -- into a hole in a rubber sheet, and then simplytaped the sheet over the smartphone's camera.

Paired with the phone's camera, the ball lens can resolve features onthe order of 1.5 microns, small enough to identify different types ofblood cells, researchers said.

The enhanced phones could help doctors and nurses diagnose blooddiseases in developing nations where many hospitals and rural clinicshave limited or no access to laboratory equipment -- and can send thereal-time data to colleagues around the globe for further analysis anddiagnosis -- the researchers said.
