PURPOSE Grating-based x-ray phase-contrast imaging is a fast developing new modality not only for medical imaging, but as well for other fields such as material sciences. While these many possible applications arise, the knowledge of the noise behavior is essential. METHODS In this work, the authors used a least squares fitting algorithm to calculate the(More)
A simulation framework for coherent X-ray imaging, based on scalar diffraction theory, is presented. It contains a core C++ library and an additional Python interface. A workflow is presented to include contributions of inelastic scattering obtained with Monte-Carlo methods. X-ray Talbot-Lau interferometry is the primary focus of the framework. Simulations(More)
Increased interest over the levels of pharmaceuticals detected in the environment has led to the need for new approaches to manage their emissions. Inappropriate disposal of unused and waste medicines and release from manufacturing plants are believed to be important pathways for pharmaceuticals entering the environment. In situ treatment technologies,(More)
Osteoarthritis is a common cartilage disease, particularly in societies with aging population. Over 80% of the people over 75 years are affected in the USA. MRI and X-ray can be used to image cartilage, but both approaches suffer from specific drawbacks. X-ray TalbotLau interferometers (TLI) have the potential to unite benefits from both modalities.(More)
Sphäroidale und phag-ähnliche Form des Hühner-Leukosis-Virus (BAI, Stamm A) wird der Existenz eines kontrahierbaren Systems (Interaktion mit ATP) zugeschrieben. Formveränderungen des Viruspartikels unter ATP-Einfluss werden in vitro dargestellt, wobei Parachlormorcuribenzoat, Phenylmercuriborat und N-Äthylmaleimid als Inhibitoren wirken.
