Abstract: Methods, hardware, and software transform 2D anatomical X-ray images into 3D renderings for surgical preparation. X-ray images of a body part are identified by camera model. A contour is extracted from the X-ray. Each anatomical region of the contour is assigned 2D anatomical values.

The template is aligned with the x-ray image and projected on an image plane to obtain a 2D projection model. The template is modified to match the anatomical values by comparing the projection with the corresponding anatomical values. Best matching points on the contour for extracted silhouette vertex projections are identified and used to back-project corresponding silhouette vertices. The 3D template is deformed so that its silhouette vertices match the target positions, resulting in a 3D reconstruction for the X-ray image.
