英文摘要	Conference Name:2013 International Conference on Human Health and Medical Engineering, HHME 2013. Conference Address: Wuhan, China. Time:December 7, 2013 - December 8, 2013.; Purpose: To achieve finite element modeling (FEM) of internal carotid siphon segment (ICSS) based on the CT data and discuss the modeling method. Methods: With GE Lightspeed 64-MSCT scan, we get the CT data of ICSS with 0.625 mm of thickness. The data is loaded to the software of "Mimics" with the dicomformat images. By the combination of threshold setting and manual editing, the three-dimensional geometry model was calculated. Used the mesh function of FEA module, the vascular surface grid was gained and saved as fluid grid format, which was directly loaded to Gambit software to divide fluid mesh and check its grid quality. Finally the whole process is finished. Result: The model of ICSS was successfully obtained. It has the same good anatomical shape as a real object. The fluid grid data can be directly loaded to hydromechanics finite element software for further research. Conclusion: FEM of carotid siphon based on CT data has the characteristics of accuracy and high efficiency. It provides basic medium for hemodynamic research. ? 2014 WIT Press.
