Blood vessel simulation analysis method, equipment and device, computer equipment and storage medium

Abstract

The invention relates to a blood vessel simulation analysis method and device, computer equipment and a storage medium. The method comprises the following steps that: computer equipment constructs a three-dimensional model of a target blood vessel section according to at least two two-dimensional image sequences of the target blood vessel section, acquires the position of a cutting surface of the three-dimensional model, and calculates the average blood flow velocity of the target blood vessel section according to the gray value gradient of the position of the cutting surface of the three-dimensional model and image frames corresponding to the positions of the cutting surfaces; and performing simulation calculation according to the three-dimensional model of the target blood vessel section, the preset boundary condition and the preset simulation model to obtain a simulation result of the target blood vessel section. In the method, the computer equipment can identify the gray value gradient of the inlet position and the gray value gradient of the outlet position of the target blood vessel section and calculate the average blood flow rate, so that the simulation result of the target blood vessel section obtained based on the average blood flow rate is more accurate.

Description

technical field [0001] The present application relates to the field of intelligent medical technology, in particular to a blood vessel simulation analysis method, equipment, device, computer equipment and storage medium. Background technique [0002] In recent years, due to the further development of medical imaging equipment in terms of clarity and other aspects, the accuracy and clinical acceptance of various applications for calculating the Fractional Flow Reserve (FFR) of blood vessels through the post-processing of medical images have been greatly improved. There has been a significant improvement. [0003] In the prior art, the boundary conditions of the fluid dynamics analysis equations are constructed by manually selecting the thrombolysis in myocardial infarction (TIMI) time obtained by the staff, and based on the constructed boundary conditions, the vascular blood flow Simulation calculation of reserve fraction. [0004] However, the way of manually determining t...
