Method and system for measuring eddy currents generated by an mri system component

Abstract

A system and method for measuring gradient-induced eddy currents generated by an MRI system component configured to be located near an MRI gradient coil are provided. The system includes a current driver configured to deliver a driving current to the MRI gradient coil and a sensing coil array configured to measure an eddy current magnetic field from the MRI system component while the driving current is delivered. The sensing coil array comprises a plurality of pickup coils each configured to generate a voltage signal indicative of the eddy current magnetic field at a location of the respective pickup coil. One or more hardware processors are configured to characterize the eddy current magnetic field in the MRI system component based on the voltage signal generated by each of the plurality of pickup coils and the driving current delivered to the gradient coil. The eddy current magnetic field characterization is outputted.
