利用CT对受伤的人头颅进行扫描
得到头颅的CT图像资料
将图像导入Mimics软件(试用版)中
建立了带有组织的受损眼眶的3D模型
模型中包括视神经、眼球、眶脂体、眼眶.将此模型导入ANSYS软件中
并建立有限元模型进行分析计算.有限元模拟结果表明:在正常颅内压和眼内压的作用下
视神经的最大应力发生在视神经与眼球接触部位.
To gain the CT picture of head
an injured human′s head was scanned by the CT.Then the CT pictures was imported into the Mimics software(trial version) to establish the 3D geometry model with tissues of the optic nerve in damaged eye socket.The eyeball
adipose body of orbit and eye socket were incuded in the model.A finite element model was established in the ANSYS software by use the 3D geometry model.The FE simulation results show that in the normal intracranial pressure and intraocular pressure
the maximum stress occurred in the contact part with the optic nerve and eyeball.
