1. A method for generating a three-dimensional image, comprising:
- acquiring two or more fluoroscopic projection images at different view angles relative to a region of interest, wherein the two or more fluoroscopic projection images are aligned using at least one of a fiducial marker or an anatomical structure; and
reconstructing at least one three-dimensional image from the two or more fluoroscopic projection images.

Abstract
A technique is provided for generating a three-dimensional image from fluoroscopic projection images. The technique allows for the acquisition of fluoroscopic images at different perspectives relative to a region of interest. One or more three-dimensional images may then be reconstructed from the fluoroscopic projection images. The three-dimensional images may then be displayed to provide anatomic context for the fluoroscopic application. A fluoroscopic projection image, such as the most current fluoroscopic image, may be superimposed on the three-dimensional image if desired.
