In this work, we have investigated and developed a backprojection-filtration (BPF)-based algorithm for ROI-image reconstruction from circular cone-beam data ...
The unique property of this modified algorithm is that it can reconstruct exact ROIs in midplane and approximate ROIs in other planes from transversely ...
In Section 5, we describe our iterative ROI reconstruction algorithm from ROI-truncated data and we prove our main convergence results. In Section 6, we present.
Qualitative and quantitative results demonstrate that the proposed BPF-type algorithms can not only accurately reconstruct ROI images from truncated projections ...

Nov 28, 2007 · The results of the experimental studies demonstrate that, from certain truncated data, the BPF algorithm can reconstruct ROI images with quality ...
Our method iterates an operator combining ROI-truncated projections, inversion by the operator and appropriate regularization operators.
Oct 22, 2024 · In this paper, a tent BPF (T-BPF) algorithm is developed based on the data rebinning method, which was performed by first rearranging the cone- ...
The results demonstrated that the ROI-image quality reconstructed from truncated data using the BPF algorithm was comparable to that reconstructed from complete ...
