1. A method of X-ray imaging, comprising:
determining energies of photons emitted by an X-ray source and attenuated by an object that are detected by an energy-discriminating radiation detector;
generating photon count data by counting a number of detected photons in a plurality of energy bins of the energy-discriminating radiation detector that includes a first energy bin and an adjacent second energy bin; and
generating an X-ray image of the object using the photon count data, wherein detected photons determined to have an energy within a gap region between a maximum energy threshold of the first energy bin and a minimum energy threshold of the second energy bin are not included in the photon count data used to generate the X-ray image of the object.
