Claim 8:
9. The method for calculating an index of microcirculatory resistance based on myocardial blood flow and CT image according to claim 8, wherein the step S07 further comprises: for different types of bends of the blood vessels, calculating a pressure difference from the inlet to an outlet using a three-dimensional model; in comparison with a calculation of two-dimensional axisymmetric model, establishing a database for storing correction coefficients of various types of bending relative to two-dimensional axisymmetric results;
after obtaining the pressure, obtaining a corrected pressure difference from the inlet to the outlet with reference to the correction coefficients in the database, and then calculating IMR.
