The NIR FI (Near-Infrared Fluorescence Imaging) system is a sophisticated medical imaging setup designed for high-contrast visualization and intraoperative detection of NIR fluorescence with indocyanine green. The system includes specialized laparoscopes, a camera head with enhanced NIR sensitivity, and a light source tuned to 805 nm for optimal excitation. It supports multiple imaging modes, allowing for detailed assessments of tissue perfusion and structure, and is equipped with automatic light control features for precise imaging in both NIR and visible light spectrums.
