1. A system for placing a surgical implant into a patient comprising:
- a computer processor;
an input system to input dimensions of the surgical implant;
a tracking sensor for sensing three-dimensional position information of a surgical instrument to which the surgical implant is removably coupled, the tracking sensor transmitting the position information to the computer processor;
a display in communication with the computer processor and operable to display an image;
a memory in communication with the computer processor, the memory including computer instructions that when executed by the computer processor cause the computer processor to;
overlay a graphical representation of the surgical implant on the image prior to moving the surgical implant into the patient to ensure appropriate dimensions of the surgical implant;
generate an icon representing the surgical instrument and the mounted surgical implant; and
overlay the icon on the image to represent the real-time position of at least one of the surgical instrument or the surgical implant relative to the image and the patient;
generate a first and a second two-dimensional digitally reconstructed radiograph (DRR) image from a three-dimensional image of an anatomy of the patient;
generate a two-dimensional representation of the appropriate size of the surgical implant for display relative to the first and the second digital reconstructed radiograph image; and
wherein the overlay of the icon is used to determine an appropriately sized surgical implant based upon the two-dimensional representation relative to both the first and second digital reconstructed radiograph image.

Abstract
Images taken before a surgical procedure by an imager are displayed by a computer and overlaid with graphical representations of instruments and/or surgical implants. The graphical representations can be used to determined appropriate sizes of the surgical implants and trajectories for placement. Also, the images can be used in the operating room. The graphical representations can be updated in real-time to correspond to movement of the instruments in the operating room.

6. A method for placing a surgical implant into a patient comprising:
-
displaying a three-dimensional image of an anatomy of the patient through which an appropriately dimensioned implant is selected to be passed; selecting the surgical implant, wherein the surgical implant is operable to be detachably mounted to a surgical instrument; tracking three-dimensional position information of the surgical instrument on which the surgical implant is mounted; and generating an icon representing the surgical instrument and the mounted surgical implant and superimposing the icon on an image, the icon of the surgical instrument representing the real-time position of the surgical instrument projected into the image and the icon corresponding to the appropriately sized implant; viewing a graphical overlay of the surgical implant relative to a first image of the patient and a second image of the patient; wherein selecting the surgical implant includes determining the appropriately sized surgical implant based on the dimensions of the graphical overlay relative to both the first image of the patient and the second image of the patient. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)

15. A method for placing a spinal fusion cage into a patient comprising:
-
displaying a three-dimensional image of an anatomy of the patient through which the spinal fusion cage is to be passed; viewing a graphical overlay of the spinal fusion cage relative to a first image of the patient and a second image of the patient to view dimensions and a proposed implanted position of the spinal fusion cage relative to the patient; selecting the spinal fusion cage to include an appropriate dimension that is within an exterior dimension of a bone of the patient, wherein the appropriate dimension is determined by viewing the graphical overlay of the spinal fusion cage relative to the first image of the patient and the second image of the patient; mounting the selected spinal fusion cage to a surgical instrument; tracking three-dimensional position information of the surgical instrument on which the spinal fusion cage is mounted; determining a location of the spinal fusion cage by tracking three-dimensional position information of the surgical instrument; generating an icon during a navigation procedure representing the determined real-time position of the spinal fusion cage with the appropriate dimensions of the appropriately sized spinal fusion cage relative to the image; and displaying the icon superimposed on the image. - View Dependent Claims (16, 17, 18, 19)

20. A system for placing a surgical implant into a patient comprising:
-
a computer processor; an input system to input modeled dimensions of the surgical implant; a tracking system including a first portion operably associated with the surgical implant and a second portion remote from the first portion, wherein at least one of the first portion or the second portion is operable to sense three-dimensional position information of a surgical instrument to which the surgical implant is removably coupled and transmitting the position information to the computer processor; a display in communication with the computer processor and operable to display at least a first image and a second image; a memory in communication with the computer processor, the memory including computer instructions that when executed by the computer processor cause the computer processor to; overlay a graphical representation of the surgical implant on the at least the first image and the second image prior to moving the surgical implant into the patient to ensure appropriate dimensions of the surgical implant; generate an icon representing the surgical instrument and the mounted surgical implant; overlay the icon on the at least the first image and the second image to represent the real-time position of at least one of the surgical instrument or the surgical implant relative to the image and the patient to determine an appropriately sized surgical implant based upon the graphical representation of the surgical implant relative to both the at least the first and the second image. - View Dependent Claims (21, 22)
