Disponível em: http://repositorio.ipen.br/handle/123456789/31283.http://repositorio.ipen.br/handle/123456789/31283In this paper, we compare different industrial tomography algorithms to present the result of gamma scanning as a two-dimensional image of density distribution. In two-dimensional gamma scanning, an unconventional irradiation geometry is used and consequently many classic image reconstruction algorithms cannot be used. We tested two iterative reconstruction methods: ART (Algebraic Reconstruction Technique) and MART (Multiplicative Algebraic Reconstruction Technique). The iteration steps of both methods were intercalated with various filters: mean filter, median filter, anisotropic diffusion and total variation. The use of these filters greatly improves the quality of reconstruction. We report the obtained results.1-7openAccesstomographyalgorithmsalgebragamma sourcesTexto completo de evento0000-0002-4316-8335https://orcid.org/0000-0002-4316-8335
