Computation of Hemodynamics in the Circle of Willis [PDF]
Stroke, 2007 Background and Purpose— Wall shear stress (WSS) and pressure are important factors in the development of cerebral aneurysms. We aimed to develop a computational fluid dynamics simulator for flow in the complete circle of Willis to study the impact of variations in vessel radii and bifurcation angles ...
