WESTFORD, Mass., Oct. 19 -- LightLab Imaging L.L.C. began a first round of human studies of its optical biopsy forceps and the latest generation of its optical coherence tomography (OCT) ultra high-resolution imaging platform. The study, being conducted at Duke University, is focused on detecting precancerous tissues in patients diagnosed with "Barrett's esophagus," and directing the associated tissue biopsies. Barrett's esophagus is a condition associated with gastroesophageal reflux disease, when the normal tissue of the esophagus is replaced over time by tissues more similar to those...Read full articleRelated content from Photonics MediaArticlesLabel-Free Imaging Shows Dynamics of Intracellular Cargo TransportUntil now, scientists have relied on fluorescence microscopy techniques to study intracellular cargo transport, a vital process to maintaining essential cellular functions.
