Detailed knowledge of the hemodynamics in cerebral aneurysms is valuable not only for understanding their formation and rupture but also for clinical evaluation and treatment. However, important hemodynamic quantities are difficult to measure in vivo. In this paper a patient-specific method for modeling the hemodynamics of cerebral aneurysms from in vivo anatomical images is described, and the flow patterns ...
