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.
