Systems and method for measuring and mitigating radio frequency (“RF”) induced currents on electrical leads, electrodes, and other electrically conductive objects present in the bore of a magnetic resonance imaging (“MRI”) scanner when the MRI scanner is operated to image an object or subject are described. The methods described in the present disclosure can be implemented as a pre-scan procedure to obtain images from which the current induced on the electrical lead can be estimated. This information can then be used to adjust the RF excitation used in a subsequent pulse sequence to mitigate induced currents and reduce heating in the lead. As such, the methods described in the present disclosure provide for improved patient safety.
