1. A system, comprising:

  • an implantable pulse generator;

    a plurality of electrodes configured to be operably coupled to the implantable pulse generator, the plurality of electrodes including a return or reference electrode and further including other electrodes; and

    a programmable external device configured to program the implantable pulse generator,wherein the system configured to;

    measure a first monopolar electrical impedance between a first one of the other electrodes and the return or reference electrode;

    measure a second monopolar electrical impedance between each of the other ones of the other electrodes and the return or reference electrode;

    measure a bipolar electrical impedance between the first one of the other electrodes and each of the other ones of the other electrodes;

    determine the amplitude of a field potential at each of the other electrodes based on the measured first monopolar electrical impedance, each of the second monopolar electrical impedances, and each of the measured bipolar electrical impedances; and

    determine the relative positions of the electrodes based on each of the determined field potential amplitudes.
