Abstract

The Helmholtz-Zentrum Hereon, Germany, is operating the user experiments for microtomography at the beamlines P05 and P07 using synchrotron radiation produced in the storage ring PETRA III at DESY, Hamburg, Germany. Attenuation-contrast and phase-contrast techniques were established to provide an imaging tool for applications in biology, medical science and materials science. In the recent years we rebuilt the data preprocessing pipeline before reconstruction to provide different scanning techniques to investigate samples larger than the field of view of the x-ray beam. Within this paper the hardware requirements and calibration used at the imaging stations will be given. Furthermore, we adjust the preprocessing pipeline to deal with different mechanical accuracies of the translation / rotation stages used for addressing the full volume of the sample. Several examples using low photon energies at P05 and high photon energies at P07 will demonstrate the new stitching pipeline.
