A novel magnetic resonance elastography transducer concept based on a rotational eccentric mass: preliminary experiences with the gravitational transducer

Abstract

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 f _VIB and low 2nd harmonic-to-f _VIB ratio result in low nonlinearity and high data fidelity in both phantom and in vivo examples.
