1. An X-ray imaging system that produces one or more fan-shaped beams, comprising:

  • a target for emitting X rays upon being struck by electrons from an electron source, said target comprising at least one target focal spot; and

    one or more graded multilayer optic devices in communication with said target to transmit at least a portion of said X rays through total internal reflection to produce said one or more fan-shaped beams, said graded multilayer optic devices, comprising;

    a first graded multilayer section for redirecting and transmitting X rays through total internal reflection including,a high-index layer of material comprising a first complex refractive index n1 having a real part Re (n1) and an imaginary part β

    1;

    a low-index layer of material comprising a second complex refractive index n2 having a real part Re (n2) and an imaginary part β

    2; and

    a grading zone disposed between said high-index layer of material and said low-index layer of material, said grading zone having a grading layer comprising a third complex real refractive index n3 having a real part Re (n3) and an imaginary part β

    3 such that Re(n1)>

    Re(n3)>

    Re(n2).
