FDA clears new 3D dental x-ray device based on UNC research.

A new 3D x-ray technology, developed through a collaboration between Carolina scientists in the Department of Physics and Astronomy and the Adams School of Dentistry, will identify dental issues earlier with more detail and less radiation.

Carolina professors Otto Zhou and Jianping Lu have spent 20 years refining an x-ray source technology that uses carbon nanotubes to make x-ray machines smaller, faster, safer and sharper. And that perseverance has paid off.

The U.S. Food and Drug Administration (FDA) has now approved a 3D x-ray device called PORTRAY enabled by Shou and Lu’s novel x-ray technology.

“This 3D technology offers a better way to identify dental disease earlier,” said Zhou, David R. Godschalk Distinguished Professor of Physics and Astronomy. “For the patient, this means you can start treatment earlier, improving the quality of dental care.”
