1. An x-ray scanning system comprising:
a movable x-ray source configured to produce incident x-ray radiation having end-point x-ray energy greater than about 200 keV; and
a movable disk chopper wheel, configured to be irradiated by, and to attenuate, the incident x-ray radiation, the movable disk chopper wheel further defining one or more slits configured to pass the incident x-ray radiation through the movable disk chopper wheel for scanning a target.
