论文摘要
由于非线性效应，我们研究了X射线断层扫描的重建工件。对于非凸金属对象，我们分析了金属物体边界上拐点的条纹伪像的新现象。我们使用与适当几何形状相关的共素分布概念来表征所有可能的伪影的位置和强度。
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 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.
