Vortex Analysis of Intra-Aneurismal Flow in Cerebral Aneurysms

Figure 3

Example of variations to vortex core structure across 5 data points along the cardiac cycle: marked waveforms represent a point in the cardiac cycle for each data point. The black structure is the extracted vortex core(s) while gray is an aneurysm. The top row is for SA2 which had a lower DVO (less stable) than the bottom row from TA2 which had a higher DVO (more stable). All cores were extracted using the [normalized] -criterion method. The mean [normalized] threshold values were used to extract the vortex core and only vortex cores with a volume ≥ 0.5 mm³ were saved.
