The effect of different image reconstruction techniques on ...
Iterative reconstruction had favourable results for the DECT analysis: a significantly smaller spread for each material in the ρ e-Z eff space and lower Z eff and ρ e residuals (on average 24 and 25% lower, respectively). In terms of image quality assurance, the techniques FDK, Iterative FDK and SART provided acceptable results.
A Motion Compensation Approach for Oral and Maxillofacial ...
the analytical algorithm (e.g. FDK), with a first-order motion compensation during the back-projection step, without introducing significant artifacts. When motion is large, a dedicated FDK 30,31 or an iterative reconstruction algorithm may be appropriate for the final motion-compensated reconstruction.
