Numerical simulations of hemodynamics for this model is carried out. Based on the clinical patient-specific CT data of thoracic aortic aneurysm, image segmentation is carried out by MIMICS 11 and an optimized surface model of thoracic aortic aneurysm is constructed, which is imported into ANSYS ICEM CFD 11.0, where the volume meshes and boundary layer meshes are generated, and CFD analysis is performed. Numerical simulation is performed using a finite volume method. A finite element model for hemodynamics analysis of patient-specific thoracic aortic aneurysm is built. Distribution and changes of streamlines, velocity vector, pressure and wall shear stress are obtained for the patient-specific model. Such models with digital and patient-specific features can be applied to hemodynamic analysis of thoracic aortic aneurysm. Rupture mechanism of thoracic aortic aneurysms in a patient can be analyzed based on this kind of models., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,

articleAbstract=三维重建基于CT的胸主动脉瘤有限元模型并进行血流动力学数值模拟，为分析胸主动脉瘤的血流动力学机理及其临床治疗提供理论依据。依据临床胸主动脉瘤患者CT数据，结合MIMICS 11数字化影像处理软件，获取胸主动脉瘤的优化表面模型。随后导入ANSYS ICEM CFD 11.0进行胸主动脉瘤模型的有限元网格划分。最后在ANSYS CFX 11.0中完成胸主动脉瘤的血流动力学分析。建立临床上适用于胸主动脉瘤患者血流动力学分析的有限元模型。获得了个性化胸主动脉瘤模型中血液流场的流线、速度矢量、血管壁面压力和血管壁面切应力的分布和变化。模型具有数字化、个性化特征，可用于胸主动脉瘤血液动力学计算和分析临床胸主动脉瘤患者动脉瘤的破裂机理。, authors=^{付文宇1，乔爱科2}, authorsList=付文宇;乔爱科,
