Abstract

The invention discloses a vascular blood flow simulation method based on a mechanical equation and a related device. The method comprises the steps of obtaining characteristic data of a blood vessel;constructing a three-dimensional cavity model and a blood vessel wall model of the blood vessel according to the characteristic data, and defining a calculation area; discretizing the calculation areato generate an initial grid for describing the calculation area; carrying out encryption processing on the initial grid to generate a fine grid calculation area; carrying out roughening processing onthe initial grid to generate a coarse grid calculation area; calculating the coarse grid calculation area to obtain a final blood flow parameter of each coarse grid point in the coarse grid calculation area; generating an initial blood flow parameter of each fine grid point in the fine grid calculation area according to the final blood flow parameter of each coarse grid point; and based on the initial blood flow parameter of each fine grid point, calculating the fine grid calculation area to obtain the final blood flow parameter of each fine grid point in the fine grid calculation area. Accurate and efficient simulation of blood flow in the blood vessel can be realized.

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 and related devices based on mechanical equations. 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 simplification of the discretized grid; For some importa...
