ABSTRACT:
A multilayer x-ray reflector or reflectors are used with a source of radiation for narrow bandwidth or dual energy radiographic imaging applications. In one aspect, a unique multilayer design permits two distinct x-ray energies of narrow bandwidth to be reflected at the same incident angle for use in dual energy applications. In another aspect, several multilayer reflectors are employed in a slit scanning system. In yet another aspect, an elongated radiation source and a multilayer x-ray reflecting structure are combined to provide an x-ray or gamma ray source.
