Abstract: The invention discloses a method for processing a blood vessel image. The method comprises the following steps: acquiring image data of an interested blood vessel section; acquiring blood flow parameters of the interested blood vessel section; detecting and analyzing the image data of the interested blood vessel section to obtain reference information, wherein the reference information comprises lumen contour parameters and medial membrane contour parameters of the interested blood vessel section; obtaining reference lumen information according to the mesomembrane contour parameters; and calculating to obtain a fractional flow reserve value of the interested blood vessel section according to the blood flow parameters, the reference information and the reference lumen information. The bloodvessel image processing method disclosed by the invention can realize more accurate calculation of the blood vessel pressure difference. The invention further provides a blood vessel image processingsystem, calculation equipment and a storage medium.
