Method and apparatus for performing stereotactic surgery
First Claim
1. A stereotactic navigation system for navigating an instrument to a target site within a patient, said stereotactic navigation system comprising:
- a stereotactic head frame defining a navigable patient space and operable to be coupled to the patient and used to assist in guiding the instrument to the target site; and
a tracking device removably coupled to said stereotactic head frame and operable to track the position of the instrument relative to the stereotactic head frame, wherein said tracking device is further operable to be removed from the stereotactic head frame during imaging of the patient with the stereotactic head frame.

Abstract
A stereotactic navigation system for navigating an instrument to a target within a patient may include a stereotactic head frame, an imaging device, a tracking device, a controller and a display. The stereotactic head frame is coupled to the patient and is used to assist in guiding the instrument to the target. The imaging device captures image data of the patient and of the stereotactic head frame. The tracking device is used to track the position of the instrument relative to the stereotactic head frame. The controller receives the image data from the imaging device and identifies the stereotactic head frame in the image data and automatically registers the image data with navigable patient space upon identifying the stereotactic head frame, while the display displays the image data.
