Rational Approximations for Tomographic Reconstructions
Abstract. We use optimal rational approximations of projection data collected in X-ray tomography to improve image resolution. Under the assumption that the object of interest is described by functions with jump discontinuities, for each projection we construct its rational approximation with a small (near optimal) number of terms for a given accuracy threshold. This allows us to augment the me...
متن کاملImproving Analytical Tomographic Reconstructions Through Consistency Conditions
This work introduces and characterizes a fast parameterless filter based on the Helgason-Ludwig consistency conditions, used to improve the accuracy of analytical reconstructions of tomographic undersampled datasets. The filter, acting in the Radon domain, extrapolates intermediate projections between those existing. The resulting sinogram, doubled in views, is then reconstructed by a standard ...
متن کاملA Model Based Method for Tomographic Reconstructions of Nanoparticle Assemblies
Small angle X-ray scattering is a primary tool for resolving the crystal structures of self-assembled nanoparticle superlattices [1]. However, it is not quite informative when periodic lattices are broken into clusters due to their inhomogeneity. Therefore, it is desirable to develop a method to rapidly reconstruct the three-dimensional architecture of cluster ensembles in real space. Conventio...
متن کاملSupport Detection for SAR Tomographic Reconstructions from Compressive Measurements
The problem of detecting and locating multiple scatterers in multibaseline Synthetic Aperture Radar (SAR) tomography, starting from compressive measurements and applying support detection techniques, is addressed. Different approaches based on the detection of the support set of the unknown sparse vector, that is, of the position of the nonzero elements in the unknown sparse vector, are analyze...
متن کاملAdaptive Graph-based Total Variation for Tomographic Reconstructions
Sparsity exploiting image reconstruction (SER) methods have been extensively used with Total Variation (TV) regularization for tomographic reconstructions. Local TV methods fail to preserve texture details and often create additional artifacts due to over-smoothing. Non-Local TV (NLTV) has been proposed as a solution to this but lacks continuous update and is computationally complex. In this pa...
