1. An x-ray imaging system comprising: (a) an x-ray source adapted to generate a pulsed x-ray beam having a predetermined frequency and to apply the pulsed x-ray beam to an object to be imaged; (b) an x-ray detector adapted to detect x-ray radiation from the object and generate temporal x-ray data based on the x-ray radiation; and (c) a temporal data analyzer adapted to apply a temporal signal process to the temporal data to remove at least a portion of the temporal data having a different frequency than the predetermined frequency.
