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.
Claims30
A system for guiding an instrument through a region of a subject, comprising:
- a non-imaging instrument 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;
- and
- a display device, wherein an instrument image is generated based on the tracked location of the first tacking device, the second tracking device, and the generated image.
A system for guiding an instrument through a region of a subject, comprising:
- an instrument moveable through the subject;
- a first tracking device connected adjacent to a distal end of 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 positioned outside the subject and connected to the dynamic 3D ultrasound probe;
- 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, respectively.
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 first tracking device connected near a distal end of 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;
- and
- determining a relative position of the instrument and the ultrasound probe based on tracked positions of the first tracking device and the second tracking device, respectively.
