Identification of nonlinear beam-hardening effects in X-ray tomography
Yiran Wang
We study streaking artifacts caused by beam-hardening effects in X-ray computed tomography (CT). The effect is known to be nonlinear. We show that the nonlinearity can be recovered…

Streak artifacts from non-convex metal objects in X-ray tomography
Yiran Wang, Yuzhou Zou
We study artifacts in the reconstruction of X-ray tomography due to nonlinear effects. For non-convex metal objects, we analyze the new phenomena of streak artifacts from inflectio…
