Franz Pfeiffer (born 25 November 1972 in Kösching, Germany) is a German physicist known for his contributions to the development of Phase-contrast X-ray imaging and its applications in biomedical research.
[1] This enlarged the potential of X-ray phase imaging for clinical use as before the technique was only possible at synchrotron facilities.
Pfeiffer further introduced the extraction of a supplementary signal (so-called "dark-field signal") sensitive to porous microstructure of a sample based on X-ray scattering.
Further Pfeiffer is known for his research in X-ray Ptychography,[3] X-ray tensor tomography,[4][5] grating-based Neutron interferometric imaging[6] and iterative CT reconstruction algorithms.
In 2011 he was awarded the Leibniz Prize for his achievements in X-ray physics.
