Visual Exploration of Simulated and Measured Flow Data

Abstract

The acquisition and generation of flow data played an essential role in medical research and partially also in treatment planning. An important example is the measurement and simulation of blood flow. This is motivated by increasing evidence that blood flow changes in a characteristic way as a consequence of vascular diseases, such as aneurysms and aortic dissection. These diseases primarily occur in regions with complex (sometimes even turbulent) and instable flow that changes strongly over time. Blood flow may be measured, e.g., with Doppler ultrasound or special MRI sequences. As an alternative, blood flow may be simulated with computational fluid dynamics (CFD). Simulations ...
