A novel magnetic resonance elastography transducer concept based on a rotational eccentric mass: preliminary experiences with the gravitational transducer.
CONCLUSION: The table top measurements are in concordance with the theory behind a transducer based on a rotational eccentric mass. The resulting constant displacement amplitude irrespective of <i>f</i><sub>VIB</sub> and low 2<sup>nd</sup> harmonic-to-<i>f</i><sub>VIB</sub> ratio result in low nonlinearity and high data fidelity in both phantom and in vivo examples.
