1. A surgical instrument navigation system operable to track a position of a surgical instrument relative to a patient space, comprising:
- a tracking subsystem operable to capture real-time position data indicative of the position of the surgical instrument; and
a processor adapted to access image data representative of the patient space in a selected orientation and to process the image data and the position data from the tracking subsystem, the processor operable to generate a three-dimensional representation of the surgical instrument as it would visually appear from either of at least two different perspectives and to overlay the representation of the surgical instrument onto the image data of the patient.

Abstract
A surgical instrument navigation system is disclosed that allows a surgeon to invert the three-dimensional perspective of the instrument to match their perspective of the actual instrument. A data processor is operable to generate a three-dimensional representation of a surgical instrument as it would visually appear from either of at least two different perspectives and to overlay the representation of the surgical instrument onto an image data of the patient. The image data and the representations can be displayed on a display.

13. A surgical instrument navigation system for assisting in tracking a surgical instrument in relation to a patient space, comprising:
-
a surgical instrument an imaging subsystem operable to produce image data representative of the patient space produced in relation to an image receiver and a transmitter; a tracking subsystem operable to capture in real-time position data indicative of a position of the surgical instrument; a processor operable to process the image data and the position data from the tracking subsystem, the processor operable to generate a three-dimensional representation of the surgical instrument as it would visually appear from either the perspective of the transmitter or the perspective of the image receiver and to overlay the representation of the surgical instrument onto the image data of the patient in the orientation. - View Dependent Claims (14, 15, 16, 17, 18, 19)
