1. A system to determine a contour of a surface of a patient, the system comprising:
- a flexible member having an edge, a top surface, and a bottom surface, wherein the top surface and the bottom surface are substantially co-extensive and have an area greater than the edge, wherein the flexible member is at least partially woven including a first fiber interlaced with a second fiber; and
a tracking device including a first coil formed on the first fiber and a second coil formed on the second fiber, wherein the tracking device is operable to determine a distinct position information regarding the surface of the patient;
wherein the flexible member is formable to a contour of the patient and is operable to assist in a registration of a patient space to an image space.

Abstract
A system can be used to determine a position of a structure in physical space. The system can include a flexible member, such as a drape, cloth, sheet, etc. that can include one or more trackable devices associated therewith. The trackable devices can be incorporated into the weave of a woven cloth or the matrix of a polymer member. The trackable devices can be used within a tracking system to determine the location of the trackable devices.

18. A method to determine a contour of a surface of a patient, the method comprising:
-
overlaying a flexible member atop an exterior surface of the patient to define a sterile field over the portion of the patient covered with the flexible member; tracking a distinct location of a tracking device affixed to the flexible member with a tracking system; determining the location of the tracking device regarding the surface of the patient; and registering an image space with a physical space defined relative to the flexible member based at least in part on the determined location of the tracking device. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 39)

30. A method to determine a contour of a surface of a patient, the method comprising:
-
positioning a flexible member formed of a first fiber woven with a second fiber on the patient; determining a contour of the patient in acquired image data; tracking a location of a tracking device including a first coil formed around the first fiber and a second coil formed around the second fiber; determining a contour of the patient via tracking the location of the tracking device; correlating the determined contour in the image data and the determined contour of the patient; and registering an image space and a patient space. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38)
