Electro-optic RF magnetic resonance signal based on a Ti:LiNbO3 waveguide

Résumé

The use of metallic coaxial cables in Magnetic Resonance Imaging could induce local high Specific Absorption Rate (SAR). Optical fiber link could be a promising alternative to coaxial cables for MRI to ensure patient safety. Here, the conversion of the Radio-Frequency magnetic field into an electric signal by electro-optic effect was demonstrated and characterized. A waveguide crystal is used together with an endoluminal coil to demonstrate the ability of such transducer to perform a deported characterization of Radio-Frequency magnetic field at 3T. The results show a good agreement with theoretical values and a minimum magnetic detectable field of pT order.
