Patent Images
1. A method of performing instrument tracking on an image comprising:
- collecting in a collection device that rotatably moves a plurality of static 2D images using an image processing computer;
computing on a tracking data processor at least one of a position and orientation of at least one instrument for said plurality of static images; and
automatically displaying on an output device each image in said collected plurality of static 2D images in a continuous sequential image by image manner creating 3D information perceived by a user of said position and orientation of said instrument, wherein said user perceived 3D information is created by said continuous sequential image by image motion through the animation process, wherein said at least one position and orientation of said at least one instrument is projected on each said image.

Abstract
The present invention relates to a method and system apparatus for instrument tracking on a series of images. The method relates to performing instrument tracking on an image. The method comprises collecting at least one image and computing at least one of a position and orientation of at least one instrument for the at least one collected image. The method further relates to displaying at least one, some or all of the collected and computed data either separately or in any combination.

9. A method of performing instrument tracking on a series of static images using an imaging device, comprising:
-
collecting a series of 2D static images in a collection device that rotatably moves using an image processing computer; calibrating said series of 2D static images in said collection device using said image processing computer such that at least one of a position and orientation of at least one instrument may be accurately displayed in each image of said series of static images; selecting at least one image of said series of 2D static images to be a current image; computing in a tracking data processor said at least one position and orientation of said at least one instrument for said current image; projecting said at least one position and orientation within said current image; displaying said current image on an output device; and automatically repeating said selecting, computing, projecting, and displaying steps to create 3D information perceived by a user of said position and orientation of said instrument by creating motion through the animation process using a sequential image by image presentation of said series of 2D static images. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An apparatus for performing instrument tracking on a series of static images, the apparatus comprising:
-
a collection device that rotatably moves and is adapted to collect a series of static images using an image processing computer; a processing device communicating with at least said collection device and adapted to create 3D information perceived by a user by creating motion through the animation process by automatically and continuously presenting an image by image animation of said series of static images including at least one of a position and orientation of at least one instrument and at least one image of said at least one instrument located at said at least one of a position and orientation; and an output communicating with at least said processing device and adapted to display said image by image animation of said series of static images. - View Dependent Claims (18, 19)
