Few-view single photon emission computed tomography (SPECT) reconstruction based on a blurred piecewise constant object model
Paul A Wolf, Jakob H Jørgensen, Taly G Schmidt +1
A sparsity-exploiting algorithm intended for few-view Single Photon Emission Computed Tomography (SPECT) reconstruction is proposed and characterized. The algorithm models the obje…
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…
First-order convex feasibility algorithms for iterative image reconstruction in X-ray CT
Emil Y. Sidky, Jakob S. Jørgensen, Xiaochuan Pan
Iterative image reconstruction (IIR) algorithms in Computed Tomography (CT) are based on algorithms for solving a particular optimization problem. Design of the IIR algorithm, ther…
