Characterization of pulsatile flow in arterial models may provide an insight on various flow-induced changes due to morphology, blood viscosity, wall elasticity, flow rate, etc. In this work we studied how the dynamics of a pulsatile flow changes with wall elasticity, stenosis degree and Reynolds number in aortic phantoms by using ultrasonic (US) and optical (O) particle imaging velocimetry (PIV)...
Shear wave elastography can provide quantitative evaluation of soft tissues viscoelastic properties based on the measurement of shear wave speed in the medium. Muscular and cerebral tissues are composed of fibers which induce a strong anisotropic effect on the mechanical behavior. Currently, these tissues cannot be accurately represented by existing elastography phantoms and there is an urgent need...
