Artifacts and visible singularities in limited data X-ray tomography

ET Quinto - Sensing and Imaging, 2017 - Springer
We describe a principle to determine which features of an object will be easy to reconstruct
from limited X-ray CT data and which will be difficult. The principle depends on the geometry …

Characterization of metal artifacts in X‐ray computed tomography

HS Park, JK Choi, JK Seo - Communications on Pure and …, 2017 - Wiley Online Library
Metal streak artifacts in X‐ray computerized tomography (CT) are characterized here using
the notion of the wavefront set from microlocal analysis. The metal artifacts are caused …

On the strength of streak artifacts in filtered back-projection reconstructions for limited angle weighted x-ray transform

LV Nguyen - Journal of Fourier Analysis and Applications, 2017 - Springer
In this article, we study the limited angle problem for the weighted X-ray transform. We
consider two approximate reconstructions by applying filtered back-projection formulas to …

Theorems that Characterize Artifacts for Arbitrary Limited X-ray CT Data

L Borg, J Frikel, J Jørgensen, ET Quinto - 2017 - opus4.kobv.de
This article provides a mathematical classification of artifacts from arbitrary incom-plete X-ray
tomography data when using the classical filtered backprojection algorithm. Usingmicrolocal …
