Description

Abstract In a recent publication, we investigated the prospect of measuring the outer three-dimensional (3D) shapes of nano-scale atom probe specimens from tilt-series of images collected in the transmission electron microscope. For this purpose alone, an algorithm and simplified reconstruction theory were developed to circumvent issues that arise in commercial “back-projection” computations in this context. In our approach, we give up the difficult task of computing the complete 3D continuum structur... Title of program: STOMO version 2 Catalogue Id: AEFS_v2_0 Nature of problem A local electron tomography algorithm of specimens for which conventional back projection may fail and or data for which there is a limited angular range (which would otherwise cause significant 'missing-wedge' artefacts). The algorithm does not solve the tomography back projection problem but rather locally reconstructs the 3D morphology of surfaces defined by varied scattering densities. Versions of this program held in the CPC repository in Mendeley Data AEFS_v1_0; STOMO version 1.0; 10.1016/j.cpc.2009.10.023 AEFS_v2_0; STOMO version 2; 10.1016/j.cpc.2011.11.008 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
