Abstract
A method for estimating an offset between a first group and a second group of contacts with respect to a longitudinal direction. Each group of contacts includes a plurality of electrodes arranged along a surface of a body of a lead. The method includes the steps of: (a) Selecting a number of electrode pairs, each electrode pair including an electrode of the first contact group and an electrode of the second contact group, and measuring the impedances between the electrodes of each selected electrode pair; (b) pre-conditioning the measured impedances for attenuating unwanted noise to generate pre-conditioned impedances, and (c) determining the lead offset using the pre-conditioned impedances.
