Laser ‘Pill’ Boosts Esophagus Imaging

Facebook X LinkedIn Email
BOSTON, Jan. 14, 2013 — Physicians may soon have an easy and painless way to screen the esophagus for precancerous cellular changes, thanks to a pill-size device that provides detailed imaging of the upper gastrointestinal tract. Developed by researchers at the Wellman Center for Photomedicine at Massachusetts General Hospital (MGH), the system involves a capsule containing optical frequency domain imaging (OFDI) technology — a rapidly rotating laser tip emitting a near-infrared beam of light and sensors that record light reflected back from the esophageal lining. The technique offers several advantages...Read full article
