	Abstract

The surface geometry of an intracranial stent (ICS) for cerebral aneurysm is reconstructed by using micro-CT to import computational fluid simulations. The reconstructed stent with STL format is composed of 170,948 triangles with 0.04 mm spatial resolutions. The boundary condition of the surface is clear without any reflection effects by X-ray introduced into the stainless steel stent. The computational simulations of blood flow with small implants, such as stent or coil will be a designable way to control blood flow in/on a cerebral aneurysm and repair the disease. Micro-CT has a possibility of detecting the 3-D geometry of a small implant, such as ICS and may be useful to 3-D reconstruction and integration to computational simulation.

Key Words: stent, cerebral aneurysm, micro-CT, CFD
