From: High-frame rate vector flow imaging of the carotid bifurcation
VFI patterns in CB various shapes. a) Tight angle between ICA and ECA: streamline laminar flow (red and orange vectors) during systole. b) Wide angle (> 45°) between ICA and ECA. The maximum velocity red vectors in the bulb hit the flow divider (short arrow), leading to the detachment of layers and generating vortex flow (*). CCA = Common carotid artery. ICA = Internal carotid artery. ECA = External carotid artery
