How to characterize and decrease artifacts in limited angle tomography using microlocal analysis.
Inverse Probl.:55769 (2014)
Verlagsversion Volltext
Zum Artikel
The filtered backprojection algorithm (FBP) in limited angle tomography reliably reconstructs only specific features of the original object and creates additional artifacts in the reconstruction. While the former is well understood mathematically, the added artifacts have not been studied very much in the literature. In our paper Inverse Problems 29125007 we mathematically explain why additional artifacts are created by the FBP and Lambda-CT algorithms for a limited angular range, and we derive an artifact reduction strategy using microlocal analysis.
