Embodiment Construction

[0065] A method for obtaining blood flow reserve fraction of the present invention, comprising:

[0066] Step S1, acquiring image data and physiological parameters related to the coronary artery and the heart, and constructing a corresponding three-dimensional model by processing the image data;

[0067] Step S2, solving the hemodynamic governing equation according to the three-dimensional model to obtain the hemodynamic parameter distribution of the coronary arteries in the region expressed by the three-dimensional model;

[0068] The hemodynamic parameters at the boundary of the three-dimensional model are obtained by using the lumped model and solving it by genetic algorithm;

[0069] Step S3, calculating the fractional blood flow reserve according to the relevant parameters obtained in step S2.

[0070] Step S4, generating a corresponding fractional blood flow reserve report based on the result of step S3.

[0071] Each step will be described in detail below in conjuncti...

Abstract

The invention discloses a method, device and system for acquiring the fractional flow reserve, and a computer storage medium. The method for acquiring the fractional flow reserve comprises: a step S1,acquiring image data and physiological parameters related to a coronary artery and a heart, and constructing a corresponding three-dimensional model by processing the image data; a step S2, solving ahemodynamic control equation according to the three-dimensional model to obtain a hemodynamic parameter distribution of the coronary artery in a region expressed by the three-dimensional model, wherein the hemodynamic parameter of a boundary portion of the three-dimensional model is obtained by using a lumped model and a genetic algorithm; a step S3, calculating the fractional flow reserve of theangiostenosis site according to the relevant parameter obtained in step S2; and step S4, generating a corresponding fractional flow reserve report on the basis of the result of step S3. The method can accurately calculate and acquire of the fractional flow reserve FFR of the coronary artery of a patient.

Description

technical field [0001] The present invention relates to data processing of medical images, in particular to a method, device, system and computer storage medium for obtaining fractional flow reserve (FFR) based on medical image data. Background technique [0002] Coronary angiography was once considered the "gold standard" for the diagnosis of coronary heart disease, but it can only qualitatively evaluate the degree of lesion stenosis, but cannot quantitatively evaluate the impact of lesion stenosis on coronary physiological function, so it may overestimate or underestimate the lesion The severity of the disease leads to undertreatment of lesions that require treatment or overtreatment of lesions that do not require treatment. In 1993, NicoPijls et al. proposed a new index of calculating coronary blood flow through blood pressure measurement—Fractional Flow Reserve (FFR). After long-term basic and clinical research, FFR has become a recognized index for functional evaluatio...
