Poly (vinyl alcohol) cryogel, PVA-C, is presented as a tissue-mimicking material, suitable 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 Young's modulus were obtained varying from 50kPa 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).
