Abstract：
The uniformity of ICT image is impaired by beam hardening and the inconsistency of detector units responses. This paper analyzes the beam hardening and the nonlinearity of the detector's output. The correction factors are determined experimentally by the detector's responses with different absorption length. The artifacts in the CT image of a symmetrical aluminium cylinder have been eliminated after calibration.
