Abstract
A CT scanner includes a gantry that supports and houses components of the CT scanner. A camera is mounted to the gantry. As the gantry rotates about an axis of rotation, the camera captures a photographic external image of the patient at a plurality of rotational positions. A computer generates a three dimensional external image from the plurality of external images. The three dimensional external image is registered relative to a three dimensional CT image generated from a plurality of x-ray images.
