The circle of Willis (CoW) is a ring-like arterial structure located in the base of the brain and is responsible for the distribution of oxygenated blood throughout the cerebral mass. To investigate the effects of the complex 3D geometry and anatomical variability of the CoW on the cerebral hemodynamics, a technique for generating physiologically accurate models of the CoW has been created using a...
The Circle of Willis (CoW) is a ring-like structure blood vessels at the base of the brain that distributes arterial blood to the cerebral mass. 1D and 3D CFD models of the Circle of Willis have been created to simulate clinical scenarios such as inclusions in afferent arteries and absent circulus vessels. Both models capture cerebral haemodynamic auto-regulation using proportional-integral controller...
