1. A system for screening an object, comprising:

  • a conveyor to move the object through an inspection region;

    a first X-ray source configured to transmit X rays through the object for generating a vertical X-ray projection view of the object;

    a second X-ray source configured to transmit for X rays through the object for generating a horizontal X-ray projection view of the object, wherein the vertical X-ray projection view and horizontal X-ray projection view spatially overlap and define the inspection region;

    a first array of detectors, wherein the first array of detectors comprises a first set of dual-energy sensitive detectors and a first set of energy discriminating detectors positioned adjacent, not behind, each other relative to the first X-ray source; and

    a second array of detectors, wherein the second array of detectors comprises a second set of dual-energy sensitive detectors and a second set of energy discriminating detectors positioned adjacent, not behind, each other relative to the first X-ray source and wherein the second array of detectors are positioned substantially perpendicular to the first array of detectors within the inspection region.
