Optimization of high-energy microtomography using synchrotron radiation at PETRA III

Microtomography using synchrotron radiation has proven to be a valuable tool for characterizing samples within biology, medical science, paleontology and materials science. A variety of attenuation contrast and phase-contrast imaging techniques were established to focus on spatial resolution, density resolution, and temporal resolution. In this paper, we focus on the recent developments at beamline P07 at PETRA III, Hamburg, Germany, for high-energy microtomography to provide high-density resolution for the study of a fossil tooth sample. Due to the integration of two independent CCDs for alternating use within the X-ray detector the imaging throughput was doubled. The concept, the alignment process, and first results are presented
