Solution existence, uniqueness, and stability of discrete basis sinograms in multispectral CT
Yu Gao, Xiaochuan Pan, Chong Chen
This work investigates conditions for quantitative image reconstruction in multispectral computed tomography (MSCT), which remains a topic of active research. In MSCT, one seeks to…
Empirical average-case relation between undersampling and sparsity in x-ray CT
Jakob S. Jørgensen, Emil Y. Sidky, Per Christian Hansen +1
In x-ray computed tomography (CT) it is generally acknowledged that reconstruction methods exploiting image sparsity allow reconstruction from a significantly reduced number of pro…
Convex optimization problem prototyping for image reconstruction in computed tomography with the Chambolle-Pock algorithm
Emil Y. Sidky, Jakob H. Jørgensen, Xiaochuan Pan
The primal-dual optimization algorithm developed in Chambolle and Pock (CP), 2011 is applied to various convex optimization problems of interest in computed tomography (CT) image r…
Accelerated gradient methods for total-variation-based CT image reconstruction
Jakob Heide Jørgensen, Tobias Lindstrøm Jensen, Per Christian Hansen +3
Total-variation (TV)-based Computed Tomography (CT) image reconstruction has shown experimentally to be capable of producing accurate reconstructions from sparse-view data. In part…
