Low-rank flat-field correction for artifact reduction in spectral computed tomography
Katrine O Bangsgaard, Genoveva Burca, Evelina Ametova +2
Spectral computed tomography has received considerable interest in recent years since spectral measurements contain much richer information about the object of interest. In spectra…
A Bayesian Approach to CT Reconstruction with Uncertain Geometry
Frederik H. Pedersen, Jakob S. Jørgensen, Martin S. Andersen
Computed tomography is a method for synthesizing volumetric or cross-sectional images of an object from a collection of projections. Popular reconstruction methods for computed tom…
Regularization by Denoising Sub-sampled Newton Method for Spectral CT Multi-Material Decomposition
Alessandro Perelli, Martin S. Andersen
Spectral Computed Tomography (CT) is an emerging technology that enables to estimate the concentration of basis materials within a scanned object by exploiting different photon ene…
Direct 3D Tomographic Reconstruction and Phase-Retrieval of Far-Field Coherent Diffraction Patterns
T. Ramos, Bastian E. Grønager, Martin Skovgaard Andersen +1
We present an alternative numerical reconstruction algorithm for direct tomographic reconstruction of a sample refractive indices from the measured intensities of its far-field coh…
Technical Note: Proximal Ordered Subsets Algorithms for TV Constrained Optimization in CT Image Reconstruction
Sean Rose, Martin S. Andersen, Emil Y. Sidky +1
This article is intended to supplement our 2015 paper in Medical Physics titled "Noise properties of CT images reconstructed by use of constrained total-variation, data-discrepancy…
