1. A method for determining the relative lead position of multiple-electrode leads, comprising:

  • measuring impedance vectors between lead electrodes by measuring monopolar impedances for all lead electrodes, measuring bipolar impedances between each lead electrode on opposing leads, and correcting the bipolar impedances for adjacent tissue impedance;

    determining the relative minima of the impedance vectors;

    inferring the relative position of the leads based on the relative minima of the impedance vectors; and

    displaying the inferred relative lead positions to a user.
