Figures
- Fig 1.
A–D, Different flow patterns found in AcomA aneurysms are shown in the top row. Pictures of the streamlines colored by the magnitude of the velocity and their path from the A1 segment to the A2 segments in 4 selected aneurysms for each flow type are shown in the bottom row.
- Fig 2.
Streamlines colored with the velocity magnitude (top row) and instantaneous WSS distributions (bottom row) at the peak systole for 4 selected aneurysms with different flow types (from left to right: flow types A, B, C, and D) whose MWSS is of 10, 60, 200, and 150 dyne/cm2, respectively. The same color scale of 150 dyne/cm2 is used for all the WSS images. Only flow type C aneurysm is ruptured.
