High-quality surface extraction is a crucial prerequisite for high-quality flow simulation and analysis in cerebral aneurysms. In this paper we present a two-step approach that first efficiently extracts a smooth surface from segmented aneurysms by means of MPU Implicits and then further improves the mesh quality to generate high-quality surfaces as input for the numerical simulation of blood flow in cerebral aneurysms. The presented work is an important step towards methods to assess growth, rupture risk, and therapeutic alternatives in the treatment of cerebral aneurysms.
