Data correction in reconstructing the image of CBS in the manner of filtered back-projection

CBS is a non-destruction detection technology, which was recently developed. The different in contrast with the conventional CT is that the conventional CT uses the integration of the X-ray absorptivity of the various apparatus to reconstruct the image, and that the CBS uses the rate at which the incidence ray are scattered from a particular region to reconstruct the image. The paper primarily analyses the data correction in reconstructing the image of CBS in the manner of classical filtered back-projection. (authors)
