The endoscopic device, called angle-resolved low coherence interferometry, is used to reach the esophagus through the nose. Physicians can then shine light in short intervals, and the sensors capture and interpret the light as it is reflected back to the physician. The method helps spot abnormal changes in cells occurring in the epithelium, where approximately 85 percent of all cancers begin.
Researchers say the technique can be used as testing for patients who may have Barrett’s esophagus and also has potential as a testing system for other types of cancer, such as colon cancer and cervical cancer.
