Pink Beam Ptychography — •Björn Enders, Pierre Thibault, Martin Dierolf, Andreas Fehringer, Marco Stockmar, Irene Zanette, and Franz Pfeiffer — Department of Physics (E17) and Institute of Medical Engineering (IMETUM)

In the field of X-ray Coherent Diffraction Imaging we use a scanning technique called ptychography to image 2D and 3D specimen at the nanoscale. From the ptychographically reconstructed sample projections we use computed tomography to obtain fully quantitative 3d electron density maps of bone or other material science specimen. We report on latest results in ptychographic tomography on bone and on its applications to less coherent synchrotron x-ray sources of wider spectral bandwidth (pink beam sources). Providing higher flux, those sources promise a significant speed increase that would facilitate the usage of ptychography tomography for a broader application spectrum.
