Comparing x-ray phase-contrast imaging using a Talbot array illuminator to propagation-based imaging for non-homogeneous biomedical samples
Autor: Mirko Riedel, Kirsten Taphorn, Alex Gustschin, Madleen Busse, Joerg U. Hammel, Julian Moosmann, Felix Beckmann, Florian Fischer, Pierre Thibault, Julia Herzen
Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-9 (2023)
Abstract Phase-contrast computed tomography can visualize soft tissue samples with high contrast. At coherent sources, propagation-based imaging (PBI) techniques are among the most common, as they are easy to implement and produce high-resolution ima

Spectral X-ray dark-field signal characterization from dual-energy projection phase-stepping data with a Talbot-Lau interferometer
Autor: Kirsten Taphorn, Lennard Kaster, Thorsten Sellerer, Alexander Hötger, Julia Herzen
Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-8 (2023)
Abstract Material-selective analysis of spectral X-ray imaging data requires prior knowledge of the energy dependence of the observed signal. Contrary to conventional X-ray imaging, where the material-specific attenuation coefficient is usually preci

X‐ray Stain Localization with Near‐Field Ptychographic Computed Tomography
Autor: Kirsten Taphorn, Madleen Busse, Johannes Brantl, Benedikt Günther, Ana Diaz, Mirko Holler, Martin Dierolf, Doris Mayr, Franz Pfeiffer, Julia Herzen
Publikováno v: Advanced Science, Vol 9, Iss 24, Pp n/a-n/a (2022)
Abstract Although X‐ray contrast agents offer specific characteristics in terms of targeting and attenuation, their accumulation in the tissue on a cellular level is usually not known and difficult to access, as it requires high resolution and sens

Direct Differentiation of Pathological Changes in the Human Lung Parenchyma With Grating-Based Spectral X-ray Dark-Field Radiography
Autor: Korbinian Mechlem, Franz Pfeiffer, Julia Herzen, Fabio De Marco, Daniela Pfeiffer, Kirsten Taphorn, Thorsten Sellerer, Manuel Viermetz
Publikováno v: IEEE Transactions on Medical Imaging. 40:1568-1578
Diagnostic lung imaging is often associated with high radiation dose and lacks sensitivity, especially for diagnosing early stages of structural lung diseases. Therefore, diagnostic imaging methods are required which provide sound diagnosis of lung d

Publikováno v: Developments in X-Ray Tomography XIII.
Phase-contrast imaging is one of the standard X-ray imaging methods at synchrotron beamlines and has already proven to be beneficial for soft-tissue visualization. However, most implementations use single-distance inline phase-contrast techniques, an

Dual-Energy X-Ray Dark-Field Material Decomposition
Autor: Korbinian Mechlem, Julia Herzen, Franz Pfeiffer, Ruizhi Tang, Thorsten Sellerer, Kirsten Taphorn
Publikováno v: IEEE Transactions on Medical Imaging
Dual-energy imaging is a clinically well-established technique that offers several advantages over conventional X-ray imaging. By performing measurements with two distinct X-ray spectra, differences in energy-dependent attenuation are exploited to ob

Publikováno v: Scientific Reports, Vol 10, Iss 1, Pp 1-9 (2020)
Scientific Reports
X-ray dark-field (XDF) imaging accesses information on the small-angle scattering properties of the sample. With grating interferometry, the measured scattering signal is related to the sample’s autocorrelation function, which was previously demons
