Abstract EN
Limited-angle computed tomography (CT) has great impact in some clinical applications.
Existing iterative reconstruction algorithms could not reconstruct high-quality images, leading to severe artifacts nearby edges.
Optimal selection of initial image would influence the iterative reconstruction performance but has not been studied deeply yet.
In this work, we proposed to generate optimized initial image followed by total variation (TV) based iterative reconstruction considering the feature of image symmetry.
The simulated data and real data reconstruction results indicate that the proposed method effectively removes the artifacts nearby edges.
