from patient-specific imaging data, researchers can fine-tune their models to more accurately reflect real-world
hemodynamics.

Advanced CFD techniques, such as fluid-structure interaction (FSI) models, take this validation process a step further.
FSI simulations account for the dynamic interplay between blood flow and vessel wall deformation, providing a more
comprehensive validation of neurovascular bundle lab models. This approach is particularly valuable when studying
conditions where vessel compliance and flow dynamics are closely interrelated, such as in the case of cerebral
aneurysms.
