We develop novel X-ray imaging methods using highly brilliant synchrotron radiation and conventional laboratory X-ray sources. We mainly focus on quantitative multi-modal approaches combining spectral and phase-contrast imaging. Currently, we are aiming at applying these methods for improved breast cancer detection and for quantitative 3D virtual histology of human tissue.

Abstract: X-ray microtomography at synchrotron sources is fundamentally limited by the high radiation dose applied to the samples, which restricts investigations to non-native tissue states and thereby…
Advanced Science
Abstract: Virtual histology using X-ray micro-computed tomography offers 3D tissue visualization, yet lacks the specificity of conventional histology, where targeted stains selectively highlight features like…

Abstract: X-ray dark-field imaging enables a spatially-resolved visualization of ultra-small-angle X-ray scattering. Using phantom measurements, we demonstrate that a material’s effective dark-field signal may…
