Abstract:Cerebral aneurysm growth is influenced by hemodynamical factors, which are commonly estimated by means of a computational fluid dynamics (CFD) model of a small 3D patient-specific segment of the arterial tree. Since direct in vivo assessment of the boundary conditions for the 3D segment is often not possible, the flow pulses are generally computed with a patient-generic 1D model. The aim of this study is to evaluate the necessity of, and requirements for, full patient-specific modeling, i.e., both geometry and… Show more
A review of hemodynamic models (blood movements in the human arterial system) is carried out taking into account the elasticity of the vessel walls. A generalization of the model is formulated regarding blood as a multicomponent medium.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
