Surgical navigation with overlay on anatomical images
First Claim
1. A medical imaging system for imaging an operating region in a subject, the system comprising an imaging beam source, an imaging plate, and a display for displaying an image generated by the imaging beam on the imaging plate together with an overlay of at least one object in the operating region, the overlay generated from the position of the object, the position of the imaging beam source, and the position and orientation of the imaging plate.

Abstract
A system and method are provided for control of a navigation system for deploying a medical device within a subject, and for enhancement of a display image of anatomical features for viewing the projected location and movement of medical devices, and projected locations of a variety of anatomical features and other spatial markers in the operating region. The display of the X-ray imaging system information is augmented in a manner such that a physician can more easily become oriented in three dimensions with the use of a single-plane X-ray display. The projection of points and geometrical shapes within the subject body onto a known imaging plane can be obtained using associated imaging parameters and projective geometry.
