Title:

METHOD AND SYSTEM FOR IMAGE PROCESSING OF INTRAVASCULAR HEMODYNAMICS

Document Type and Number:

WIPO Patent Application WO/2015/041312

Kind Code:

A1

Abstract:

[Problem] The present invention addresses the problem of providing an analysis technique relating to the moving image data of a fluorescent contrast agent imaged with a microscope during a procedure, and in particular, to a method and system with which estimation of information such as BV, BF and MTT, vascular wall thickness, and the like is possible, even by fluorescent contrast agent analysis, by applying, to fluorescent contrast agent analysis, perfusion analysis methods with which estimation of information such as BV, BF, and MTT is possible.[Solution] This method for image processing of intravascular hemodynamics is characterized in that by using infrared light, moving image imaging is carried out of a portion of a vessel, as the subject of imaging, into which a specific amount of fluorescent contrast agent has been injected, the shape of the curve representing changes over time in the brightness of the image output of the moving image imaging is subjected to image analysis, and the blood volume or the volume of blood flow as non-constant data is calculated on the basis of the results of the image analysis.
