Abstract
The disclosure provides technology for analyzing video data of a fluorescent contrast agent shot by a microscope during an operation, and provides a method and system allowing information such as BV, BF and MTT, and vascular wall thickness, to be estimated by fluorescent contrast agent analysis, by applying perfusion analysis methods. The method for processing intravascular hemodynamics images is characterized by shooting video using infrared light, wherein the object of shooting is a portion of a blood vessel injected with a fluorescent contrast agent; performing image analysis of a shape of a chronological change curve of intensity values which are image outputs from the video shooting; and calculating relative data for blood volume and blood flow based on results of the image analysis.
