1. A method for analyzing an object comprising:
- prescanning the object using a multiple energy X-ray device to determine prescan information;
transmitting the prescan information to a processor coupled to a computed tomography device;
performing a computed tomography scan of at least a portion of the object based on the prescan information, wherein the computed tomography scan generates computed tomography scan data and is performed using the computed tomography device; and
performing a metal artifact correction on the computed tomography scan data, wherein the prescan information is used to perform the metal artifact correction on the computed tomography scan data.

Abstract
A method or apparatus for analyzing an object includes an X-ray prescanner that performs a prescan of the object to determine prescan information about the object. Then, a CT scanner performs a CT scan on at least one plane of the object based on the prescan information to determine CT information. In one embodiment, if the CT scan of the object includes or is in the vicinity of metal, then metal artifact correction of a reconstructed image from the CT scan is performed based on the prescan information. In another embodiment, a processor analyzes the CT information and the prescan information to determine whether to update the prescan information based on the CT information
