Abstract: Abstract For specimen characterization, X-ray microscopy offers a variety of advantages like non-destructive investigations and reduced preparation effort for the samples. Orientation measurements are possible using diffraction contrast tomography (DCT). However, lateral resolution is lower… read more here.

DOI: 10.1080/17415977.2016.1201662
Abstract: A new nonlinear level-set regularization method to reconstruct the complex refractive index distribution with in-line phase contrast tomography measurements is presented under the assumption that the index is piecewise constant. The nonlinear iterative approach is… read more here.
