OCT advances promise endoscopic, image-guided therapies

BOSTON, MA, USA--At Massachusetts General Hospital's Wellman Center for Photomedicine and Harvard University, scientists have been working to apply endoscopic optical-coherence tomography (OCT) technology to identify cancer in the gastrointestinal (GI) tract. They have developed a tool that combines optical frequency-domain imaging (OFDI)--a second-generation OCT--with controllable laser thermal therapy in a separate optical channel.
