Abstract

A display may display a region of an anatomy that is not within the field of effect of an instrument. The additional views may assist in determining a location and orientation of an instrument. The instrument may be tracked with a tracking system to make the determination of image data to display.

First claim

What is claimed is:

1. A system for displaying information, comprising:
a navigation system having a tracking system configured to determine a location of an instrument relative to at least a first portion of a subject and a second portion of the subject;
a display device configured to simultaneously display a first image of the first portion of the subject and a second image of the second portion of the subject; and
a navigation processor configured to execute instructions to determine the location of the instrument for illustrating with the display device a representation of the instrument in both a first direction relative to the first image of the subject and a second direction relative to the second image of the subject;
wherein the first image and the second image are images of portions a distance away from the instrument;
wherein the first direction is opposite to the second direction.

2. The system of claim 1 , wherein the display device displays simultaneously both the first direction and the second direction along an axis relative to both the first image and the second image.

3. The system of claim 2 , wherein the first image of the subject is an inferior endplate of a first vertebrae and the second image of the subject is a superior endplate of a second vertebrae, and the first direction of the first image is opposite the second direction of the second image.

4. The system of claim 3 , wherein the display device is configured to display simultaneously both the representation of the instrument in the first direction relative to the first image and the representation in the second direction of the instrument relative to the second image.

5. The system of claim 4 , wherein the navigation processor is further configured to determine a first distance of the instrument from at least one of the inferior endplate of the first vertebrae or a second distance of the instrument from the superior endplate of the second vertebrae;
wherein the display is configured to display at least one of a first distance amount or the second distance amount.

6. The system of claim 4 , wherein the navigation processor is configured to scale the displayed representation of the instrument relative to either of the first image or the second image.

7. The system of claim 1 , wherein the instrument includes a trial.

8. A system for displaying information, comprising:
a tracking system configured to determine a location of an instrument;
a display device configured to simultaneously display a first image portion of a subject and a second image portion of the subject including an icon representing a tracked location of the instrument; and
a processor configured to execute instructions to determine the location of the instrument for illustrating with the display device a representation of the instrument in at least one of a first perspective of the instrument relative to the first image portion of the subject and a second perspective of the instrument relative to the second image portion of the subject;
wherein the first perspective is opposite the second perspective.

9. The system of claim 8 , wherein the processor is further configured to automatically determine the first perspective of the instrument relative to the first image portion of the subject and the second perspective of the instrument relative to the second image portion of the subject and the display device is configured to display the first perspective and the second perspective.

10. The system of claim 8 , wherein the first image portion incudes a first vertebral endplate and the second image portion includes a second endplate;
wherein the processor is further configured to determine the first perspective of the instrument relative to the first endplate and the second perspective of the instrument relative to the second endplate.

11. The system of claim 10 , wherein the display device is configured to display both the first perspective and the first endplate and the second perspective and the second endplate.

12. The system of claim 11 , further comprising:
the instrument configured to move a trial member relative to the subject;
a tracking device associated with the instrument configured to be tracked with the tracking system.

13. A method of displaying information for a user, comprising:
determining a location of an instrument relative to a portion of a subject;
displaying with a display device a first image based on image data acquired of the subject including a low contrast portion of the subject;
displaying with the display device a second image based on image data acquired of the subject including a first high contrast portion of the subject;
displaying with the display device a third image based on image data acquired of the subject including a first high contrast portion of the subject;
subject including a second high contrast portion of the subject;
superimposing a first icon representing the instrument on the displayed first image;
superimposing a second icon representing the instrument on the displayed second image;
superimposing a third icon representing the instrument on the displayed third image;
wherein the second image is taken from a first direction and the third image is taken from a second direction, where the first direction is opposite the second direction.

14. The method of claim 13 , further comprising:
acquiring image data of the subject, wherein the subject includes tissue that has low contrast in the image data.

15. The method of claim 13 , further comprising:
simultaneously displaying with the display device the first image and the first icon superimposed on the first image and displaying with the display device the second image and the second icon superimposed on the second image.

16. The method of claim 13 , wherein the second image is a first endplate and the third image is a second endplate;
wherein the first endplate and the second endplate form an intervertebral space.

17. The method of claim 13 , further comprising:
updating the second icon superimposed on the second image based on a movement of the instrument.
