Abstract

The invention provides a cardiac blood flowing indicating and displaying method based on an Euler fluid simulation algorithm. The method includes three steps: initializing a cardiac blood model, namely preprocessing a cardiovascular surface model, subdividing an Euler network, and initializing a time boundary of an Euler algorithm; simulating blood fluid, namely realizing the Euler fluid simulation algorithm in real time, and simulating blood flowing circumstances in the cardiovascular system; indicatively displaying a blood flowing field, analyzing fluid in a cardiovascular system, and utilizing concise and clear symbols to indicatively display characteristics of the flowing field. Flowing of blood in the cardiovascular system is simulated completely based on a GPU (graphics processing unit), the blood flowing field can be analyzed and indicatively displayed, and the cardiac blood flowing indicating and displaying method has the advantages of being on the basis of a physical real model and good in instantaneity.
