TY - INPR A1 - Frikel, Jürgen A1 - Quinto, Eric Todd T1 - A paradigm for the characterization of artifacts in tomography N2 - We present a paradigm for characterization of artifacts in limited data tomography problems. In particular, we use this paradigm to characterize artifacts that are generated in reconstructions from limited angle data with generalized Radon transforms and general filtered backprojection type operators. In order to find when visible singularities are imaged, we calculate the symbol of our reconstruction operator as a pseudodifferential operator.
