Image-based CFD modelling of cerebral blood flow



Abstract. Detailed knowledge of the hemodynamics in the cerebral blood tree is valuable not only for studying the mechanisms of alimentation in the cortex, but also to investigate the role of hemodynamics in the development of cerebrovascular pathologies. The aim of this work is to present preliminary data processing pipeline focussing on the extraction of a 3D patient specific smooth geometric model from magnetic resonance imaging (MRI) and estimate hemodynamic factors using computational fluid dynamics (CFD).
