Abstract

The invention discloses a blood flow simulation method of blood vessel based on domain decomposition, a blood flow simulation device and a computer-readable storage medium, wherein the method comprises acquiring characteristic data of blood vessel; a three-dimensional model of blood vessel being constructed according to the characteristic data, wherein the three-dimensional model defines a computational region; the computational region being discretized to generate a grid describing the computational region; the computational area being divided into several sub-computational areas, wherein thenumber of grid points in each sub-computational area is identical; at least two sub-compute regions being simultaneously computed based on a grid to obtain blood flow parameters of that compute regions. The present application enables accurate and efficient simulation of blood flow in blood vessels.

Description

technical field [0001] The present application relates to the field of numerical simulation of blood flow, in particular to a vascular blood flow simulation method based on region decomposition, a blood flow simulation device and a computer-readable storage medium. Background technique [0002] To a certain extent, the characteristics of blood flow can reflect whether there is a disease in the blood vessel and whether the patient has a disease caused by hemodynamic changes. For example, the fractional flow reserve (FFR) can reflect the risk of ischemia, and the blood flow velocity can reflect the degree of vascular blockage, etc. . Therefore, the simulation analysis of blood flow has become a research hotspot in the field of prevention and diagnosis of vascular diseases. [0003] In the early days, due to the limitation of computer capacity, many simplifications were carried out in the simulation of blood flow, such as the simplification of the physical model and the simpli...
