Locality estimates for Fresnel-wave-propagation and stability of X-ray phase contrast imaging with finite detectors

Simon Maretzke

Coherent wave-propagation in the near-field Fresnel-regime is the underlying contrast-mechanism to (propagation-based) X-ray phase contrast imaging (XPCI), an emerging lensless tec…

Generalized SART Methods for Tomographic Imaging

Simon Maretzke

Nowadays, the field computed tomography (CT) encompasses a large variety of settings, ranging from nanoscale to meter-sized objects imaged by different kinds of radiation in variou…

Automatic alignment for three-dimensional tomographic reconstruction

Tristan van Leeuwen, Simon Maretzke, K. Joost Batenburg

In tomographic reconstruction, the goal is to reconstruct an unknown object from a collection of line integrals. Given a complete sampling of such line integrals for various angles…

Stability estimates for linearized near-field phase retrieval in X-ray phase contrast imaging

Simon Maretzke, Thorsten Hohage

Propagation-based X-ray phase contrast enables nanoscale imaging of biological tissue by probing not only the attenuation, but also the real part of the refractive index of the sam…

Regularized Newton Methods for X-ray Phase Contrast and General Imaging Problems

Simon Maretzke, Matthias Bartels, Martin Krenkel +2

Like many other advanced imaging methods, x-ray phase contrast imaging and tomography require mathematical inversion of the observed data to obtain real-space information. While an…

Regularized Newton methods for simultaneous Radon inversion and phase retrieval in phase contrast tomography

Simon Maretzke

Promoted by the advent of coherent synchrotron light sources, phase contrast tomography allows to resolve three-dimensional variations of an unknown sample's complex refractive ind…
