Figures
- Fig 1.
Examples of aneurysms with simple (A) and complex (B) flow patterns. From left to right, the visualizations show isovelocity surfaces, velocity magnitudes on a cut plane, streamlines, and WSS distribution, all at peak systole.
- Fig 2.
Examples of aneurysms with stable (A) and unstable (B) flow patterns. Visualizations at peak systole (top row of each panel) and end diastole (bottom row of each panel) are shown by using (from left to right) isovelocity surfaces, velocity magnitudes on a cut plane, streamlines, and WSS distribution.
- Fig 3.
Examples of aneurysms with large (A) and small (B) impingement regions. From left to right, the visualizations show isovelocity surfaces, velocity magnitudes on a cut plane, streamlines, and WSS distribution, all at peak systole.
- Fig 4.
Examples of aneurysms with diffuse (A) and concentrated (B) inflows. From left to right, the visualizations show isovelocity surfaces, velocity magnitudes on a cut plane, streamlines, and WSS distribution, all at peak systole.
