Videos (below) from SPIE Medical Imaging 2025 Poster submission titled, "1000 fps High-Speed Angiography Evaluation of Vortex Flow Characteristics in 3D-printed Cerebral Vascular Aneurysm Phantoms" by E.

1000 fps High Speed Angiography (HSAngio) for actual visualization of flow during systolic phase of one heartbeat (cardiac cycle)
Models 1 & 2 show a two patient-specific saccular ICA phantom used to better visualize hemodynamic flow patterns. Both videos are displayed at 30 fps with each individual frame being 1 ms each with a total of 290 ms displayed.
Blood flow is from bottom to top and there is some vessel overlap with the aneurysm and the inlet and outlet regions. The majority of the circulation inside the aneurysm is counterclockwise and is circulates mostly in the plane. The center of the main vortex is slightly left of center of the mostly circular aneurysm.
Blood flow is from bottom to top. As the contrast fills the aneurysm, most of the circulation conducts clockwise within the aneurysm, with some of the flow more into the plane. As the high-speed video progresses, more of the contrast seems to circulate into the plane. The center of the main vortex is not stable for the entire duration of the video.
