Abstract
Tilt-based electron tomography volumes are reconstructed based on acquired projections from different
directions. A limited number of projections leads to elongation artifacts along the electron beam
direction in the reconstructions, called missing wedge artifacts, which are also visible as a missing
wedge in the Fourier domain. Such errors impede meaningful and correct interpretations of investigated
samples. We proposed to use exemplar-based inpainting known from image processing for
restoration tasks. As a proof-of-concept we applied our method to an artificial dataset and showed its
applicability. Now, we collected a real dataset to validate the use of our method in a real world setup.
