| Research Abstract |
Magnetic resonance elastography (MRE) can noninvasively visualize shear waves patterns within tissue. To acquire an accurate shear modulus map in high spatial resolution in deep regions, external drivers must generate a precisely controlled high frequency and a large amplitude vibration. In this study, we develop a simple and robustly designed focused acoustic driver to enhance shear wave amplitude in deep regions and imaging programs. From the results of the experimental studies, it was shown that the system acquire an accurate shear modulus map in high spatial resolution in deep regions.
