Problems solved by technology
However, the parameters of the outlet boundary conditions and inlet boundary conditions of this method are many and complex, and it is difficult to determine the specific values, so that the pre-processing takes a lot of time; at the same time, because the method uses fluid-solid coupling, and the CFD calculation is coupled with the inlet and outlet boundary conditions , so that the CFD calculation needs to run for multiple cycles to stabilize the result

The invention relates to a method and system for simulation of bloodstream in blood vessels. The method for simulation of bloodstream in blood vessels comprises following steps: dividing blood vessels into calculating domains and analyzing domains; using a three-dimensional model area of a target area reconstructed by medical tomography image data as the calculating domain and other parts as analyzing domains; loading the analyzing domains as boundary conditions to the calculating domains; and making hydrodynamics calculations of the calculating domains loaded with the boundary conditions in order to obtain bloodstream parameters of blood vessels. The method and system for simulation of bloodstream in blood vessels are adopted so that all parameters of bloodstream can be obtained in a non-intrusive mode.
Description
technical field [0001] The invention relates to a technology for simulating blood flow in blood vessels, in particular to a method and system for simulating blood flow in blood vessels. Background technique [0002] Coronary blood circulation supplies the heart, especially the heart muscle, with oxygen and nutrients to maintain heart function. Some arterial diseases, such as atherosclerosis, can develop and evolve for a long time without clinical symptoms. For most people, ischemia occurs when atherosclerotic plaque narrows the inner walls of blood vessels by more than about 60 percent, at a time when the demands on the blood supply increase. [0003] If atherosclerotic plaque occurs in the coronary arteries, the consequences of the evolution to the later stage are that the oxygen demand of the myocardium is greater than the oxygen supply. When the myocardial oxygen supply and oxygen demand are out of balance, myocardial ischemia with systolic dysfunction, arrhythmia and e...
