Low-rank flat-field correction for artifact reduction in spectral computed tomography

Katrine O Bangsgaard, Genoveva Burca, Evelina Ametova +2

Spectral computed tomography has received considerable interest in recent years since spectral measurements contain much richer information about the object of interest. In spectra…

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…
