Enhancing Endoscopy With Optical Filters

By Iridian Spectral Technologies

endo

Endoscopic examination is a key technique used to diagnose early-stage neoplastic lesions associated with stomach and other gastrointestinal cancers. While white-light reflectance (WLR) imaging has become the standard for in vivo diagnosis using “conventional endoscopy,” this white paper details three alternatives - or supplements - to WLR that leverage the wavelength selectivity provided by optical filters:  narrow-band imaging (NBI), auto-fluorescence imaging (AFI), and endoscopic Raman spectroscopy.
