Abstract: A method of estimating response of a medical lead to an electromagnetic field includes providing a medical lead having a proximal end, a distal end, a plurality of electrodes disposed along the distal end, a plurality of terminals disposed along the proximal end, and a plurality of conductors extending along the medical lead and electrically coupling the electrodes to the terminals; individually applying a test field at each of a plurality of test positions along the medical lead using at least one excitation probe; for each application of the test field, determining a response to the application of the test field at one or more of the electrodes or terminals; generating a transfer function using a combination of the responses determined for the applications of the test field; and using the transfer function to estimate a response of the medical lead to an electromagnetic field.
