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.

Description

technical field [0001] The present invention relates to the medical field, in particular to a processing method, system, computing device and storage medium for blood vessel images. Background technique [0002] Vascular stenosis will affect the blood supply of the myocardium. Coronary angiography can show the severity of coronary stenosis, but it cannot reflect the functional changes of blood vessels. Vascular pressure difference refers to the pressure difference between the proximal end point and the distal end point of the vessel segment of interest, which can effectively reflect the blood supply function status of the blood vessel. [0003] However, the measurement of vascular pressure difference has always been a difficulty. Invasive and invasive pressure measurement of blood vessels through pressure sensors is not only a lot of work, but also has the risk of damaging blood vessels. A geometric model of the coronary system can be obtained by three-dimensional or two-d...
