VirtualFD is solution with a framework to simulate the virtual flow diverter (FD) deployment and the flow in and around intracranial aneurysms. The application takes into account the detailed mechanical properties and the hydrodynamic resistance of the FDs, both obtained from unique in-house measurements.

A measurement device has been recently developed to quantify the hydrodynamic resistance of the FDs, and this is an essential input information to the predictive model for perianeurismal flow simulations. The aim of the solution is to facilitate the in silico regulatory evaluation of flow diverters (FDs) used for the endovascular treatment of intracranial aneurisms.

The planned work for VirtualFD in ISW is to validate the solution with a medium-size cohort of clinical cases collected in a separate project at the National Institute of Mental Health, Neurology, and Neurosurgery (formerly: National Institute of Clinical Neurosciences).

The acquired results will aid the development of criteria to evaluate newly developed FDs, since at present the quality criteria for FDs are not properly defined. In addition to medical data, a database for mechanical properties and hydrodynamic resistances will be built using our in-house measurement systems.
