How little data is enough? Phase-diagram analysis of sparsity-regularized X-ray CT
Jakob S. Jørgensen, Emil Y. Sidky
We introduce phase-diagram analysis, a standard tool in compressed sensing, to the X-ray CT community as a systematic method for determining how few projections suffice for accurat…

Testable uniqueness conditions for empirical assessment of undersampling levels in total variation-regularized x-ray CT
Jakob S. Jørgensen, Christian Kruschel, Dirk A. Lorenz
We study recoverability in fan-beam computed tomography (CT) with sparsity and total variation priors: how many underdetermined linear measurements suffice for recovering images of…
