We developed an RGB camera-based imaging method to monitor the spatial and temporal hemodynamics in intraperitoneal organs using a commercially available laparoscopic imaging system. In vivo animal experiments with rats demonstrated the ability of the method to evaluate the volume fraction of total hemoglobin and its oxygen saturation of intraperitoneal organs in real time.
