We describe the fabrication of a low-cost, silicone-based phantom for elastography, which provides precise geometries and controlled stiffness. Simulations were carried out to produce synthetic MRE data and verify the performance of MRE reconstruction in ideal conditions. To our knowledge, this is the first time that simulations can be validated on exact same physical objects, making this approach very handy to optimize acquisition parameters and establish reconstruction validity criteria of elastography data. Such phantoms can be prepared with different mechanical properties, and could thus be broadly used as an accessible mean to assess the robustness of MRE tools.
