Real‐time tissue perfusion assessment using fluorescence imaging topography scanning system: A preclinical investigation

We previously developed a real‐time fluorescence imaging topography scanning (RFITS) system for intraoperative multimodal imaging, image‐guided surgery, and dynamic surgical navigation. The RFITS can capture intraoperative fluorescence, color reflectance, and surface topography concurrently and offers accurate registration of multimodal images. The RFITS prototype is a promising system for multimodal image guidance and intuitive 3D visualization. In the current study, we investigated the capability of the RFITS system in intraoperative fluorescence vascular angiography for real‐time assessment of tissue perfusion.
