Abstract:
A method for tracking movement of a movable portion of an interventional device disposed within a natural or artificial body opening is provided. In particular, image data of fiducials is acquired and therefrom an initial position of an interventional device movable portion with respect to a given coordinate system is determined. Next, real time position data from the encoders is acquired as the movable portion is moved from the initial position, and a displaced position from the initial position is determined. From this acquired information, a position of the movable portion in the coordinate system is determined using both the initial position as determined from the image data and the real time displaced position as determined from the encoders.
