Navigation information overlay onto ultrasound imagery
First Claim
1. A surgical navigation system for use in navigating a patient, said surgical navigation system comprising:
- an ultrasound machine operable to acquire an ultrasound image of the patient;
a video imaging device operable to acquire a video image of the patient;
a first localizer attached to said ultrasound machine;
a second localizer attached to said video imaging device;
a computer in communication with said ultrasound machine and said video imaging device, said computer operable to overlay the ultrasound image acquired by the ultrasound device onto the video image acquired by said video imaging device, such that the two images correspond to a common coordinate system; and
a display operable to display the overlaid image.

Abstract
A surgical instrument navigation system comprises an ultrasound machine and a computer coupled to the ultrasound machine. A memory is coupled to the computer and includes computer instructions that when executed by the computer cause the computer to generate an icon representing the surgical instrument with a tip and the surgical instrument'"'"'s trajectory and to overlay the icon on a real-time ultrasound image having an image plane, such that when the surgical instrument crosses the ultrasound image plane the format of the surgical instrument'"'"'s trajectory is changed to represent the surgical instrument'"'"'s crossing of the ultrasound image'"'"'s plane. The system also comprises a localizer coupled to the ultrasound machine, and a display coupled to the computer for displaying the generated icon superimposed on the real-time image.

7. A method for surgical navigation using overlaid images from other image modalities onto ultrasound images comprising:
-
scanning an area of interest using an ultrasound probe to acquire an ultrasound image corresponding to that area of interest;
overlaying an image from other image modalities onto the ultrasound image to create an overlaid image, such that the two images correspond to a common coordinate system;
displaying an iconic representation of a surgical instrument onto the overlaid image; and
recalculating and displaying a new location of the surgical instrument onto the overlaid image in response to a movement of the surgical instrument. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method for representing the real-time position of a surgical instrument and its trajectory in an overlaid image comprising:
-
acquiring a first image from an image device;
acquiring a second real-time ultrasound image;
overlaying the first image onto the second real-time ultrasound image, such that the two images correspond to a common coordinate system;
tracking a real-time position of the surgical instrument;
generating an icon of the surgical instrument and overlaying the icon on the overlaid image;
generating a trajectory of the surgical instrument on the overlaid image; and
changing the format of the surgical instrument'"'"'s trajectory when the surgical instrument crosses an ultrasound image plane. - View Dependent Claims (14, 15, 16, 17)
