Figure 1.

Custom software was used to convert magnetic resonance data (left) to a three-dimensional geometric model of the flow domain (center left). The three-dimensional model, in combination with patient-specific blood flow information, was used to simulate blood flow in an aneurysm during rest and exercise. During resting conditions, areas of low flow and flow stagnation exist within the aneurysm even at peak systole (center right); these regions are decreased during simulated exercise (right).
