Flow visualization in a carotid artery bifurcation model using stereoscopic PIV incorporating a 50% diameter reduction TR-PIV is an ideal technique for characterizing the complex blood flow patterns in models of both healthy and diseased vessels. Time-resolved vector maps provide insight into the complex interaction between flow conditions, changes in blood biology and vessel geometry as well as plaque buildup and stability. Results obtained provide clues to unlocking the puzzle of how damaged blood cells progress into thrombogenic conditions, rupture of plaque, and vessel damage.
