Several image stitching strategies for the X-ray tomography (CT) of large objects at high resolution are reviewed and analysed. Each allows one to increase the reconstructed volume whilst keeping the voxel size constant. The methods are compared using experimental data that have been collected at the Daresbury SRS (Stn 16.3) and ESRF (ID15) synchrotron sources. A new stitching method is presented and applied which is based on the shifting of the object with respect to the axis of rotation. (C) 2009 Elsevier B.V. All rights reserved.
