Areas of Research

Patient-specific analysis of blood flow in brain aneurysms, flow models based on magnetic resonance imaging, numerical simulation of blood flow through vascular devices.


Risk assessment of cerebral aneurysm growth with MRI flow measurements.The goal of this project is to determine the contribution of blood flow dynamics factors to risk assessment of brain aneurysms and calculate these risk factors from magnetic resonance flow imaging data augmented by flow modeling.

The Cardiovascular Flow Modeling Laboratory (CFM Lab) directed by Dr. Rayz is conducting image-based analysis of blood flow dynamics in order to improve diagnostics and treatment of cardiovascular disease. In this research, computational and experimental modeling is combined with medical imaging in order to provide patient-specific flow analysis. The CFM lab works in close collaboration with neurovascular surgeons and radiologist in several medical institutions, including University of California San Francisco, Northwestern University School of Medicine, and Barrow Neurological Institute. In our studies, image-based computational fluid dynamics (CFD) models are used to determine hemodynamic variables related to vascular disease progression and predict flow changes that would result form alternative treatment options. These models provide clinicians with valuable quantitative data not available from medical imaging alone.

While the main focus of our studies is on numerical simulations of the flow in brain aneurysms, we are also involved in modeling blood flow in other vascular territories as well as in design and optimization of biomedical devices, such as a filtration device removing chemotherapy drugs from blood. Our research projects are primary funded by the National Institute of Health.
