In this work, we adapt the previously-described robust harmonic estimation (RHE) strategy for magnetic resonance elastography (MRE) to brain imaging, and demonstrate that use of this novel signal processing tool improves the accuracy of estimated stiffness information both in a geometrically-accurate phantom and in vivo.
