Virtual chromoendoscopy technologies
| Technology | Mechanism |
|---|---|
| Narrow Band Imaging Olympus Medical Systems (Olympus, Japan) | Optic filtering of reflected light from the mucosa, isolating blue (415 nm) and green (540 nm) bands of light to enhance visualisation. |
| i-Scan and i-Scan OE PENTAX (HOYA, Japan) | Digital postprocessing image enhancement to improve mucosal pattern and vascularity. New OE technology combines this with optic filtering. |
| FICE (Fujinon, Japan) | Postprocessing technology that reconstructs a virtual image of a single wavelength in real time. |
