Magnetic Resonance Elastography (MRE) is a new imaging technique that combines the acoustic waves and MRI to retrieve elastic properties of tissue. Because MRE is non-invasive, there is great clinical interest for its use in the detection of cancer. In this work, we focus on the design of an MRE phantom to be used in the clinical commissioning of an MRE System. With the aid of newly designed pulse sequences and inversion algorithms we have developed a quality assurance process to validate the efficacy of MRE for applications to many clinical sites (i.e. prostate, cervix, uterus).
