Abstract :
Echo-PIV technique was used to obtain 2D velocity vectors of flows in a 50% stenosis model. The experiment system was constructed, including a regionally stenotic channel that mimic artery with thrombosis, a fluid circulation system, and an ultrasound imaging equipment. The stenotic channel was fabricated using a pair of male and female plastic rods, a mold, and tissue mimic phantom materials. Ultrasound contrast agents was added into fully developed laminar flow, and Echo-PIV technique was used to obtain the flow velocity pattern in the post stenosis region of the stenosis model. The simulation result of Fluent software was applied for validation. Echo-PIV technique is confirmed to be a reliable 2D velocimetry technique for blood flow in artery with thrombosis.
