1. A system for localizing a medical device within a body wherein the medical device includes an elongate body, the system comprising:
the elongate body having a diameter and at least three non-colinear localization electrodes mounted on the elongate body;
a position determination processor configured to determine positions of the at least three non-colinear localization electrodes within a non-ionizing localization field; and
a graphical representation modeling processor configured to:
receive as input the determined positions of the at least three non-colinear localization electrodes; and
construct a three-dimensional representation of the elongate body using the determined positions of the at least three non-colinear localization electrodes by defining a cylinder having a central axis connecting the determined positions of two non-colinear localization electrodes of the at least three non-colinear localization electrodes and a diameter equal to the diameter of the elongate body; and
display the three-dimensional representation of the elongate body in order to localize the medical device within the body.
