Objective
Endoscopic detection of fluorescence of indocyanine green (ICG) requires excitation in the NIR wavelength range <800nm and detection at >800nm. Commercial 3-chip endocameras can be made sensitive for the fluorescence emission in the blue channel by removing infrared blocking filters. It was the objective of the development to combine white light imaging (using the green and red channels only) and fluorescence imaging (using the blue channel) on a single 3-chip camera head. In addition, reliable pharmacokinetics of ICG perfusion images should be established.
