In many cases, a specific area or artifact will present itself in the initial data requiring refinement of the image in order to provide information regarding its characteristics and precise location. This procedural step may be conducted on targets identified on radiographs, such as calcified lesions, specific arthritic changes, specific dental features, artifacts, cultural modifications, burial practices, mummification methods, and bony fractures. Refinement may require alternative imaging projections that will free the target object from the problems of superimposition. Altered exposure settings, too, may be required to better image the target structure. Confirming pathological changes is conducted in this procedural step. This step may also be used to support biopsy efforts and artifact retrieval by using the radiographs for localization as well as pre- and postproce-dure documentation.
