i-Scan 1 = SE (surface enhancement)DetectionWith SE, the difference in luminance intensity between the pixels concerned and the surrounding pixels is analyzed and the edge components are enhanced.
i-Scan 2 = TE (tone enhancement)Pattern characterization
i-Scan 3 = OE (optical enhancement)Vessel characterizatonAn optical filter that produces bandwidth-limiting light. The main wavelenths of spectral transmission correspond to the peaks of the hemoglobin absoprtion spectrum and the light between these peaks is continously slightly emitted by raising baseline transmittance.
