Currently, safety of interventional devices is investigated using long experiments and direct measuring of induced temperature rises. A method of remotely measuring induced radiofrequency current using phase information from MRI is presented. Agreement between measurements and simulations is shown demonstrating accuracy of the remote method. This method presents a novel technique to rapidly investigate safety of different devices In Vitro.
