X-ray nano-holotomography reconstruction with simultaneous probe retrieval
Viktor Nikitin, Marcus Carlsson, Doga Gursoy +2
In conventional tomographic reconstruction, the pre-processing step includes flat-field correction, where each sample projection on the detector is divided by a reference image tak…
