Abstract: A method of reconstructing tomograms from a polychromatic X-ray transmission image and an image processing apparatus using the same. An image of a target is reconstructed in consideration of a fact that an X-ray has a polychromatic X-ray spectrum and the target is dependent upon energy of the X-ray transmitted through the target, and thus an image without any beam hardening artifacts may be generated. In addition, measurement data for X-rays with respect to all wavelengths is used to reconstruct an image, thereby reconstructing an accurate image.

Abstract: Disclosed are a system and method counting photons. Photons are counted through a plurality of counters. Each of the counters generates a flag signal indicating the availability of each counter for an output of a photon detector. The generated flag signal is input into a control unit which controls a switching unit. The control unit allows a signal to be input into a counter, which is not in dead time, based on the received flag signal.
