Numerical models of auto-regulation and blood flow in the cerebral circulation.

abstract：:Soft tissue modelling has gained a great deal of importance, for a large part due to its application in surgical training simulators for minimally invasive surgery (MIS). This article provides a structured overview of different continuum-mechanical models that have been developed over the years. It aims at facilitatin...
