New high-speed 3-D imaging system holds potential for improved cancer screening

Monday, August 1, 2011 - 11:31 in Physics & Chemistry

Researchers at the Massachusetts Institute of Technology (MIT) have developed a new imaging system that enables high-speed, three-dimensional (3-D) imaging of microscopic pre-cancerous changes in the esophagus or colon. The new system, described in the Optical Society's (OSA) open access journal Biomedical Optics Express, is based on an emerging technology called optical coherence tomography (OCT), which offers a way to see below the surface with 3-D, microscopic detail in ways that traditional screening methods can't.
