The siphon bend of internal carotid artery (ICA) has been reported as the most preferred location for stenoses. The geometry of the siphon is considered to be associated with the atherosclerotic stenosis. In the present study 3 siphon models with different curvature and planarity were experimentally studied with PIV. The velocity field of the experimental fluid in the models was measured to simulate the steady blood flow in the ICA siphon.
MicroVec 2D PIV system was used with 150mJ double pulse laser, 4 megapixel CCD camera and MicroPulse 725 synchronizer.
