Abstract: 3D printed silicone phantoms with controllable MRI signal properties Abstract: Selection of materials for development of Magnetic Resonance Imaging (MRI) phantoms is always very challenging. So far, mainly gel-based or water-filled compartments have been used for MRI phantoms. 3D printing is a promising approach which allows manufacturing potential materials with controllable MRI signal properties to mimic geometric structures and lesion heterogeneities. The aim of this study is to investigate the feasibility of using extrusion 3D printed silicone materials to mimic human tissue and its range of relaxation times on MRI.
