Using rapid prototyping technology a vascular geometry as measured by contrast enhanced MR-Angiography was transformed into a realistic solid flow phantom with large anatomical coverage and high spatial resolution. Integration into a flow circuit with patient-specific pulsatile inflow and application of time-resolved 3D MR velocity mapping permitted detail analysis of local and global flow dynamics in a realistic patient-specific environment. Different visualisation tools were applied to identify the 3D flow patterns inside the vessels which were found to be in good agreement with previously reported aortic blood flow patterns.
