Three-dimensional phase retrieval in propagation-based phase-contrast imaging
We present a solution to the phase problem in near-field x-ray (propagation) imaging. The three-dimensional complex-valued index of refraction is reconstructed from a set of projections recorded in the near-field (Fresnel) setting at a single detector distance. The solution is found by an iterative algorithm based only on the measured data and the three-dimensional tomographic (Helgason-Ludwig)...
متن کاملPropagation based phase contrast x-ray imaging of Caenorhabditis elegans
Introduction: Imaging of multicellular organisms with nano-scale resolution is one of the challenges of modern life sciences. To solve biological problems, often the combined information of several microscopy techniques is necessary. While confocal fluorescence microscopy and optical super-resolution fluorescence can detect the distribution of markers in live cells, electron microscopy (EM) off...
متن کاملPhase retrieval in in-line x-ray phase contrast imaging based on total variation minimization.
State-of-the-art techniques for phase retrieval in propagation based X-ray phase-contrast imaging are aiming to solve an underdetermined linear system of equations. They commonly employ Tikhonov regularization - an L2-norm regularized deconvolution scheme - despite some of its limitations. We present a novel approach to phase retrieval based on Total Variation (TV) minimization. We incorporated...
متن کاملThree-dimensional propagation in near-field tomographic X-ray phase retrieval.
This paper presents an extension of phase retrieval algorithms for near-field X-ray (propagation) imaging to three dimensions, enhancing the quality of the reconstruction by exploiting previously unused three-dimensional consistency constraints. The approach is based on a novel three-dimensional propagator and is derived for the case of optically weak objects. It can be easily implemented in cu...
متن کاملNijboer-Zernike phase retrieval for high contrast imaging
We introduce a novel phase retrieval method for astronomical applications based on the Nijboer-Zernike (NZ) theory of diffraction. We present a generalized NZ phase retrieval process that is not limited to small and symmetric aberrations and can therefore be directly applied to astronomical imaging instruments. We describe a practical demonstration of this novel method that was recently perform...
