Reconstruction and finite element analysis of brain hemangioma model based on CT images

Abstract

Cerebral haemangioma is a disease that seriously endangers the safety of human life. The law of its occurrence, development, and prognosis is still not completely clear. Therefore, it has attracted the attention of many researchers at home and abroad in recent years. In response to the above problems, based on the original CT data of cerebral aneurysm in patients with intracranial aneurysms, the article reconstructs the cerebral haemangioma model through Autodesk remake 3D reconstruction software. And the finite element analysis software ANSYS CFD was used to establish the reconstructed finite element model of cerebral haemangioma. Hemodynamic analysis of the model was performed to obtain the distribution and change of velocity vector of blood flow field and pressure of blood vessel wall in the model of brain haemangioma. To investigate the hemodynamic mechanism of the formation, development and rupture of cerebral haemangioma and provide theoretical basis for clinical treatment.
