Abstract: Provided are an imaging unit 104 that uses a light emitted from a second beam splitter 202 of a microscope 2 that can use an exciting light and an observation light, which is a light including a wavelength other than that of the exciting light, as a light source by switching there between and is provided with the second beam splitter 202 to image images of the same observation region of the microscope 2 in situations where the exciting light and the observation light are used as the light source and an output unit 106 that overlaps, synthesizes, and outputs the images imaged by the imaging unit 104 respectively using the exciting light and the observation light as the light source.

Abstract: [Problem] The present invention provides analysis technology relating to video data of a fluorescent contrast agent shot by a microscope during an operation, and addresses the problem of providing 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, which allow estimation of information such as BV, BF and MTT, to fluorescent contrast agent analysis. [Solution] The method for image processing of intravascular hemodynamics according to the present invention is characterized by shooting video using infrared light, wherein the object of shooting is a portion of a blood vessel injected with a standard amount of 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.
