Single-distance nano-holotomography with coded apertures

Viktor Nikitin, Marcus Carlsson, Rajmund Mokso +2

High-resolution phase-contrast 3D imaging using nano-holotomography typically requires collecting multiple tomograms at varying sample-to-detector distances, usually 3 to 4. This m…

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…

Quantitative analysis of dynamic CT imaging of methane-hydrate formation with a hybrid machine learning approach

Mikhail I. Fokin, Viktor V. Nikitin, Anton A. Duchkov

Fast multi-phase processes in methane hydrate-bearing samples are challenging for micro-CT quantitative study because of complex tomographic data analysis involving time-consuming…

Distributed optimization for nonrigid nano-tomography

Viktor Nikitin, Vincent De Andrade, Azat Slyamov +6

Resolution level and reconstruction quality in nano-computed tomography (nano-CT) are in part limited by the stability of microscopes, because the magnitude of mechanical vibration…
