This study is about an in vitro model set up with realistic in-flow conditions. The in vitro models are one to one replica of a normal aorta and were generated by rapid prototyping. One in vitro model with rigid vessel wall and four in vitro models with different flexibility of the vessel walls were employed for MRI flow experiments. The difference in flexibility grade was obtained by different vessel wall thickness of the same flexible material. In vivo and in vitro flow analysis was performed in eight planes distributed over the aorta for comparison of velocity and flow data.
