The most advanced model of our Gastroscopy functions with the AFI technique. After excitation by a short-wavelength light source, the fluorophores emit light of longer wavelengths (fluorescence). The overall fluorescence emission differs among various tissue types and these color differences in fluorescence give a clear distinction to help detecting the pathological changes in the gastrointestinal tract.

The application of AFI projects a distinct feature between normal mucosa and lesions, capturing minute pathological changes more easily.
