Abstract
We study artifacts in the reconstruction of X-ray tomography due to nonlinear effects. For nonconvex metal objects, we analyze the new phenomena of streak artifacts from inflection points on the boundary of metal objects. We characterize the location and strength of all possible artifacts using notions of conormal distributions associated with the proper geometry.
