1. A system for guiding an instrument through a region of a subject, comprising:
- a non-imaging instrument configured to be moveable through the subject;
a first tracking device connected near a distal end of the instrument;
an ultrasound imaging system to generate an image of the subject;
a second tracking device associated with the ultrasound imaging system;
a tracking system to track the first tracking device within the subject and the second tracking device;
an external imaging system configured to be external to the subject and of a different imaging modality than the ultrasound imaging system; and
a display device, wherein an instrument image is generated based on the tracked location of the first tracking device, the second tracking device, and the generated image;
wherein a second image generated with the external imaging system and the instrument image is registered to the subject and one another and displayed at one time on the display device.

Abstract
An image guided navigation system for navigating a region of a subject includes an imaging device, a tracking device, a controller, and a display. The imaging device generates images of the region of the subject. The tracking device tracks the location of the instrument in the subject. The controller superimposes an icon representative of the instrument onto the images generated from the imaging device based upon the tracked location of the instrument. The display displays the image with the superimposed instrument.

11. A system for guiding an instrument through a region of a subject, comprising:
-
an instrument configured to be moveable through the subject; a first tracking device connected along the instrument; a tracking system to track the first tracking device within the subject; a navigation system in communication with the tracking system; a dynamic three dimensional (3D) ultrasound probe configured to image the subject; and a second tracking device configured to be positioned outside the subject and connected to the dynamic 3D ultrasound probe; a display generation device configured to generate an image; wherein the navigation system is operable to determine a relative position of the instrument and the dynamic 3D ultrasound probe based on tracked positions of the first tracking device and the second tracking device; wherein a path of the instrument is displayed as a path icon superimposed on the image as an instrument path icon to display the path that the instrument has traversed through the subject. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method for guiding an instrument through a region of a subject, comprising:
-
tracking an instrument within the subject as the instrument is moved within the subject with a plurality of first tracking devices connected to the instrument; tracking an ultrasound probe configured to image the subject with a second tracking device and connected to the ultrasound probe positioned outside the subject; determining a relative position of the instrument and the ultrasound probe based on tracked positions of the plurality of first tracking devices and the second tracking device, respectively; and displaying a path of the instrument that traversed within the subject superimposed on an image generated by the ultrasound probe. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
