Journal ArticleDOI
Hard X-Ray Phase Tomography with Low-Brilliance Sources
TL;DR: This work focuses on how this method can be used for tomographic reconstructions using filtered back projection algorithms to yield quantitative volumetric information of both the real and imaginary part of the samples's refractive index.
Journal ArticleDOI
Fabrication of diffraction gratings for hard X-ray phase contrast imaging
C. David,J. Bruder,T. Rohbeck,Christian Grünzweig,Christian Kottler,Ana Diaz,Oliver Bunk,Franz Pfeiffer +7 more
TL;DR: In this article, a method for X-ray phase contrast imaging based on a grating interferometer is proposed. But the method is limited to incoherent radiation from a standard Xray tube.
Journal ArticleDOI
High-resolution brain tumor visualization using three-dimensional x-ray phase contrast tomography
Franz Pfeiffer,Franz Pfeiffer,Oliver Bunk,C. David,Martin Bech,G. Le Duc,Alberto Bravin,Peter Cloetens +7 more
TL;DR: It is demonstrated how the soft tissue sensitivity of the technique is increased and in vitro tomographic images of a tumor bearing rat brain sample are shown, without use of contrast agents.
Journal ArticleDOI
Diffractive imaging for periodic samples: retrieving one-dimensional concentration profiles across microfluidic channels.
Oliver Bunk,Ana Diaz,Franz Pfeiffer,C. David,Bernd Schmitt,Dillip K. Satapathy,J. Friso van der Veen,J. Friso van der Veen +7 more
TL;DR: A technique has been developed that allows determination of the concentration profiles of colloidal solutions or any kind of fluid under confinement and these profiles represent the ensemble average rather than individual entities and are obtained in a model-independent way.
Journal ArticleDOI
Tomographic reconstruction of three-dimensional objects from hard X-ray differential phase contrast projection images
TL;DR: In this article, a method for tomographic phase contrast imaging of centimeter sized objects was proposed based on a hard X-ray grating interferometer, which has been demonstrated to yield differential phase contrast projection images.
