An elastic phantom for the in vitro aneurysm study using particle image velocimetry

In vitro study of aneurysm flow dynamics using particle image velocimetry helped us obtain fundmental understand of the hemodynamics inside the confined geometry over a pulsatile flow. However, the majority of laboratory work has been based on silicone Sylgard 184, which is not totally rigid nor elastic enough to mimic vessel property. We try to solve this glitch by developing an elastic phantom for the in vitro aneurysm flow experiment. We will first introduce the implementation in details. We will then describe the test measurement using particle image velocimetry and compare with traditional phantom. We report any difference of flow field between the two phantoms.
