Abstract:
1. A method of localizing a medical device, the method comprising: providing an elongate medical device having a diameter and at least three non-colinear localization electrodes mounted thereon; placing the elongate medical device within a non-ionizing localization field; selecting three adjacent localization electrodes of the at least three non-colinear localization electrodes, the selected three localization electrodes including a proximal ring localization electrode, a distal ring localization electrode, and a third localization electrode; using the non-ionizing localization field to measure a location of each of the selected three localization electrodes; defining a cylinder having a central axis connecting the measured locations of the proximal and distal ring localization electrodes and a diameter equal to the diameter of the elongate medical device; projecting the measured location of the third localization electrode orthogonally to a surface of the defined cylinder; defining an orienting stripe parallel to the central axis of the defined cylinder and passing through the projected location of the third localization electrode; and constructing a three-dimensional representation of the elongate medical device within the localization field.
