Ensuring convergence in total-variation-based reconstruction for accurate microcalcification imaging in breast X-ray CT
Jakob H. Jørgensen, Emil Y. Sidky, Xiaochuan Pan
Breast X-ray CT imaging is being considered in screening as an extension to mammography. As a large fraction of the population will be exposed to radiation, low-dose imaging is ess…

Quantifying admissible undersampling for sparsity-exploiting iterative image reconstruction in X-ray CT
Jakob H. Jørgensen, Emil Y. Sidky, Xiaochuan Pan
Iterative image reconstruction (IIR) with sparsity-exploiting methods, such as total variation (TV) minimization, investigated in compressive sensing (CS) claim potentially large r…
