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 ...
Quantitative results in these studies demonstrate that the proposed BPF algorithms for circular cone-beam CT can reconstruct ROI images free of truncation ...
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.
Abstract: The circular scanning trajectory is one of the most widely adopted data-acquisition configurations in computed tomography (CT).
