Claim One:
1. An imaging system comprising: a radiation detector for receiving radiation from an examination region sequentially at a plurality of projection angles, the radiation detector producing electrical data indicative of the coordinate locations on the detector at which radiation is received, the electrical data at each of the projection angles forming a projection view of the examination region; a reconstruction processor for reconstructing a volumetric image representation from the projection views; a reprojection processor for reprojecting the reconstructed volumetric image representation to produce a reprojection view along each of the plurality of projection angles; an image isolator for isolating a subvolume of interest in the reconstructed volumetric image representation; a view comparator for comparing the projection view with the reprojection view at each of the projection angles to determine an offset; and a translator for translating each projection view by the corresponding offset, the translator being connected with the reconstruction processor to reconstruct the translated projection views into a corrected volumetric image representation.
