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.
