ABSTRACT:
A method is provided for improving visual definition in a CT X-ray image having high attenuation objects such as metal prostheses and implants. The method provides for determining extents of the high attenuation objects and reducing the artifacts that the high attenuation objects cause in the image without completely removing the high attenuation objects from the image.
