The solution presented here is based on the Neumann Boundary condition and the mirror padding scheme of the captured intensities. The obtained results are derived for the widely used Fourier Transform based TIE solver, but it is shown that they can also be applied to Multigrid based techniques. <br /> <br /> Full Text: <a class="file" href="/PLP/index.php/letters/article/view/7-2/378" target="_parent">PDF</a> <br /> <br /> <strong>References</strong> <ol> <li>K.
