Optical-digital narrowband methods for registration and improvement of biomedical images during endoscopy

Abstract

This article discusses the main narrowband opto-digital methods and technologies for obtaining digital images by endoscopic examination of the abdominal cavity. A review and comparison of the following modern methods of endoscopy IEE (image-enhanced endoscopy) with improved visualization is carried out: NBI (narrow-band imaging), LCI (linked color imaging), Laser-BLI (blue laser imaging) or LED-BLI (blue light imaging), traditional endoscopy using white light WLE (white light endoscopy) or WLI (white light imaging).
