  The application of wide field-of-view detection systems to atom probe
experiments emphasizes the importance of careful parameter selection in the
tomographic reconstruction of the analysed volume, as the sensitivity to errors
rises steeply with increases in analysis dimensions. In this paper, a
self-consistent method is presented for the systematic determination of the
main reconstruction parameters. In the proposed approach, the compression
factor and the field factor are determined using geometrical projections from
the desorption images. A 3D Fourier transform is then applied to a series of
reconstructions and, comparing to the known material crystallography, the
efficiency of the detector is estimated. The final results demonstrate a
significant improvement in the accuracy of the reconstructed volumes.
