The Construction of Cerebrovascular Model and Numerical Simulation

Abstract:

Medical image reconstruction technique has been an important research topic. Based on cerebrovascular CT image of actual victims, through extracting the contour of image, dividing the nodes and defining boundary, the paper reconstructed 2D grid model of blood vessel of brain. Using the finite element method to simulate and analyze the dynamics features of the medical image mesh model. Through experiment, the paper mainly compared the value of blood velocity and dynamics pressure, and analyzed the difference of hemodynamic parameters in different models. Finally, It found that the model I artery more easily alter form and induce arterial hemorrhage. This will provide the theoretical basis for analyzing the mechanism of Cerebrovascular diseases.
