N2 - The Poro-Viscoelastic (PVE) response of tissues or hydropolymers may be accurately modeled with as few as three parameters using the Kelvin-Voigt Fractional Derivative approach. We propose to image these parameters for simulated and experimental imaging phantoms and to analyze their values in different media. We show that each parameter can be explained in terms of stiffness and fluidity of the material and use the parameter images to differentiate two simulated imaging phantoms with apparently similar PVE properties.
