Patent Images
1. A surgical navigation system, comprising:
- a head support portion configured to support at least a head of a patient;
a processor operably associated with a first coil, a second coil and a third coil;
the first coil positioned within the head support portion and configured to generate a first navigation field encompassing a volume relative to the patient;
an alignment device including a base configured to be connected directly to the head of the patient;
the second coil integrated into the base of the alignment device, wherein the second coil is configured to sense the first navigation field produced by the first coil; and
the third coil being coupled to an instrument;
wherein the processor is configured to cooperate with at least the second coil and the third coil to determine a position of the instrument, and wherein the processor is configured to drive the first coil to generate the first navigation field and the second coil to generate the second navigation field independently such that the second navigation field is generated after ceasing the first navigation field.

Abstract
A system can be used to navigate or guide an instrument or device into an anatomy of a patient. The navigation can occur with the use of image data acquired of the patient. The image data can be registered to the patient space for navigation. Also, one or more coils can be used for tracking or localization.

10. A surgical navigation system, comprising:
-
a processor operably associated with a first coil, a second coil, a third coil, and a fourth coil; the first coil configured to generate a first navigation field encompassing a volume relative to a patient; an alignment device including a base member and a trajectory guide member, the base member configured to be connected directly to a head of the patient, the trajectory guide member selectively moveable relative to the base member and configured to guide an instrument relative thereto; the second coil coupled to the base member and configured to sense the first navigation field generated by the first coil; the third coil coupled to the trajectory guide member and configured to sense a second navigation field generated by the second coil such that the processor can determine a trajectory of the trajectory guide member relative to the base member, the second navigation field being generated independently of the first navigation field; and the fourth coil being coupled to the instrument; wherein the processor is configured to cooperate with at least the second coil and the fourth coil to determine a position of the instrument, and wherein the processor is configured to drive the first coil to generate the first navigation field and the second coil to generate the second navigation field substantially independently such that the second navigation field is generated after ceasing the first navigation field. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A surgical navigation system, comprising:
-
a processor operably associated with a first coil, a second coil, a third coil and a fourth coil; the first coil associated with a head support portion of a patient support, the processor configured to drive the first coil to generate a first navigation field; an alignment device including a base member and a trajectory guide member, the base member configured to be connected directly to a head of the patient, the trajectory guide member selectively moveable relative to the base member and configured to guide an instrument relative thereto, the second coil integrated into the base member and configured to sense the first navigation field generated by the first coil; the third coil being fixed to the trajectory guide member and configured to sense a second navigation field generated by the second coil such that the processor can determine a trajectory of the trajectory guide member relative to the base member; and the fourth coil being coupled to the instrument; wherein the processor is configured to drive the second coil to generate the second navigation field independently of the first navigation field; wherein the processor is configured to cooperate with at least the second coil and the fourth coil to determine a position of the instrument, and wherein the processor is configured to control the second coil to sense the first navigation field at a first time to facilitate guiding the alignment device relative to the patient, and to drive the second coil to generate the second navigation field at a second time after the first coil ceases generating the first navigation field. - View Dependent Claims (19, 20, 21)
