In limited data tomography, some data are missing. Because of the missing data, certain features of the object might be invisible from the data, and algorithms might create streaks are independent of the object. I will explain the artifacts and use microlocal analysis to explain how to suppress them while keeping most of the visible features of the object. I will provide reconstructions from real and simulated data that illustrate the theory.
