1. A security scanning system, comprising:

  • a first inspection system comprising;

    a housing that defines a tunnel and an inspection region;

    a conveyor that passes through said tunnel and defines a first direction through said inspection region;

    a first X-ray generator that projects a first fan of X-rays through a first slit collimator;

    a first detector array configured to receive said first fan of X-rays after they pass through said first slit collimator and said inspection region;

    a second X-ray generator that projects a second fan of X-rays through a second slit collimator, wherein said second X-ray generator is offset relative to the first X-ray generator in the first direction; and

    a second detector array configured to receive said first fan of X-rays after they pass through said second slit collimator and said inspection region; and

    a second inspection system comprising at least one of a NQR-based screening system, an X-ray transmission based screening system, an X-ray scattered based screening system, or a computed tomography based screening system.
