Paper Abstract

Multiple CT vendors have released clinical multi-detector (MD) computed tomography (CT) systems with 16cm coverage. Axial CT for voxels outside the acquisition plane does not satisfy a fundamental completeness condition, which leads to so called cone-beam artifacts. This paper revisits the iterative filtered back-projection (FBP) algorithm from 2008 and analyzes it in the context of Brerman iterations. Also, we propose a one application of this algorithm along with a recently published filtering orthogonal to the acquisition plane as a pragmatic way to considerably reduce the cone-beam artifacts in axial CT scans with high coverage.
