Description
  • We consider the reconstruction problem for limited angle tomographyusing filtered backprojection (FBP) and Lambda tomography. We use microlocalanalysis to explain why the well-known streak artifacts are present at theend of the limited angular range. We explain how to mitigate the streaks andprove that our modified FBP and Lambda operators are standard pseudodifferentialoperators, and so they do n... read more
