Abstract

Barrett’s esophagus is the main pre-cancer risk factor for the development of esophageal adenocarcinoma. Over the last decades, the incidence rate of esophageal adenocarcinoma increases exponentially in the Western World. Endoscopic screening and minimally-invasive treatment of Barrett’s esophagus are challenging due to large surface area of the lining (1-20 cm). Current microendoscopy technologies have shown high specificity; however, its sensitivity is low due to tiny field-of-view (the probe diameter is 100-1000 µm). Therefore, we proposed a novel approach with end-expandable optical fiber brush to collect endoscopic sparse imaging data and deep learning super-resolution enhancement to provide high yield diagnostics.
