1. A surgical navigation system comprising:
- a tracking device comprising a flexible substrate and multiple tracking points disposed on the flexible substrate at intervals thereon;
a surgical tracking system that tracks the positions of the tracking points;
a data link that enables communication from the flexible substrate to the tracking system; and
a registration routine associated with the tracking system, wherein the registration routine registers the positions of the tracking points to an image of a patient, and wherein the registration routine registers the positions of each tracking point in a model with previously created scan data of the patient by determining if the locations of the tracking points in the model match the scan data of the patient within a predetermined error level.

Abstract
An article to enable the creation of a model of a surface includes a flexible substrate and multiple optical tracking points attached to the flexible substrate at predetermined location. The optical tracking points can be tracked by a tracking system, and a data link enables communication from the flexible substrate to a tracking system. Also disclosed is an article that enables the creation of a model of a surface including multiple light emitting diodes attached to the flexible substrate at predetermined locations. Finally, a method of registering an article and a method for creating a model of a surface having a shape are disclosed.

13. A tracking device comprising:
-
a flexible substrate, wherein the flexible substrate has a shape that conforms to a portion of a patient; a plurality of tracking points on the flexible substrate spaced at intervals thereon; and a data link that enables communication from the flexible substrate to a surgical tracking system; wherein a registration routine associated with the tracking system registers the position of each tracking point in a model with previously created scan data of the patient by determining if the locations of the tracking points in the model match the scan data of the patient within a predetermined error level. - View Dependent Claims (14, 15, 16, 17, 18)
