Multi-component Hemodynamic Measurement in Flexible Vascular Phantom using Echo Particle Image Velocimetry

摘要：

Poly (vinyl alcohol) cryogel, PVA-C, is presented as a tissue-mimicking material, sutiable for application in magnetic resonance (MR) imaging and ultrasound imaging. Two kinds of PVA phantoms with different shape were made. Mechanical tests were performed on cylindrical samples with a pressure column, and Youngs modulus were obtained varying from SOkPa to 320kPa depending on the number of freeze-thaw cycles (one to eight).Two vascular phantoms of different elasticity were connected in the fluid system . The information of flow field in the vascular phantom was obtained using the newly developed ultrasound velocimetry technique (echo particle image velocimetry).
