In this work a new MR Elastography (MRE) technique which
can be performed on conventional MRI was developed. A
wireless TR synchronization system consists of
high-frequency radio receiver and a plain dipole antenna
tuned to the RF excitation frequency was developed. The
leak RF signal received via the dipole antenna, in the
magnet room was available as the TR synchronization
trigger then any electrical wiring from the MRI
electronics is required. The fusion of the simple MRE
sequence and the wireless synchronization pneumatic
vibration system make it possible to construct the MRE
system in any conventional MRI system.
