Optimization of Setups of Talbot-Lau X-ray Phase Contrast Imaging Systems Grating-based Talbot-Lau X-ray Interferometry is a novel
imaging
modality. Compared to standard absorption X-ray imaging,
it enables
the acquisition of differential phase contrast images.
These images
correspond to the electron density of the scanned
specimen.
Furthermore, so-called dark-field images are obtained.
These images
can visualize density inhomogeneities at micrometer
scale.
The goal of the project is to improve the setup of
Talbot-Lau X-ray
Imaging systems. So far the correlation between the
different
variables of such a system especially with polychromatic
X-ray spectra
is not known yet. Thus, the setup should be simulated and
optimized to
find the ideal setup with respect to certain structures
in the object
and the resulting images. | Project manager: PD Dr.-Ing. Christian Riess, Dr. Peter Bartl
