The present invention relates to a system and method for automatically measuring and evaluating hemodynamics in tissues of a subject's anatomical structure. In particular, the present invention relates to continuously measuring and evaluating hemodynamics in medical procedures using fluorescence imaging, wherein the administration of a fluorescent agent is controlled and automated. One aspect relates to a method for automatic perfusion evaluation of a subject's anatomy, the method comprising intravenously administering a bolus corresponding to a first fluorescent imaging agent of less than 0.01 mg of ICG per kilogram of body weight. Another aspect is a system for automatic perfusion evaluation of an anatomical structure during a medical procedure in a subject, comprising a controllable infusion pump for holding at least one first fluorescent imaging agent, wherein the infusion pump is a predefined amount of said It is configured to inject a first fluorescent imaging agent into the blood of the subject, and the system receives and analyzes a time series of fluorescence images of the anatomical tissue after injection of the first fluorescent imaging agent, and based on the analysis, the anatomical A system, configured to determine at least one perfusion parameter of the structure. |
