Abstract
A method of compensating for impedance loading effect in impedance-based location system includes determining a geometrical center for a grid of electrodes attached to a distal end of a catheter shaft, the catheter shaft further including at least one shaft electrode and an electromagnetic sensor; determining a first shift vector from the geometrical center to a longitudinal axis of the catheter shaft; determining a spline vector for the grid of electrodes; determining an angle between the spline vector and the longitudinal axis; determining a lateral grid shift vector using the first shift vector and the angle; determining a longitudinal grid shift vector extending from the geometrical center to a plane normal to the longitudinal axis and extending through the distal end; and applying the lateral grid shift vector and the longitudinal grid shift vector to each electrode of the grid of electrodes.
