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 mechanical equations, 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...
