Low frequency acoustic shear wave imaging in tissue-like media using magnetic resonance

We propose a phase contrast based magnetic resonance imaging technique that can measure small cyclic displacements (sub-micron level) like those caused by propagating acoustic shear waves in tissue-like media. Our preliminary experiments with agarose gel phantoms show that acoustic shear wave propagation can be studied and we speculate that this technique could find applications in materials science and in medical imaging.
