    Abstract: Disclosed are an image reconstruction method and a radiation imaging apparatus using the same. The radiation imaging apparatus includes a radiation emitter which emits multiple energy spectra of radiation toward an object, a radiation detector which detects multiple energy spectra of radiation passing through the object and thereby outputs measurement data, and an image reconstructor which reconstructs a radiation image of the object, based on the measurement data output by the radiation detector. The method may be used to calculate simulation data of an inner structure of the object using an image reconstruction value including information associated with densities of substances of the inside of the object, to acquire a correction value of the image reconstruction value minimizing a discrepancy between the measurement data and the simulation data and to update the image reconstruction value using the correction value.
