Sparse Matrix-Based HPC Tomography
Stefano Marchesini, Anuradha Trivedi, Pablo Enfedaque +2
Tomographic imaging has benefited from advances in X-ray sources, detectors and optics to enable novel observations in science, engineering and medicine. These advances have come w…
Real-time sparse-sampled Ptychographic imaging through deep neural networks
Mathew J. Cherukara, Tao Zhou, Youssef Nashed +4
Ptychography has rapidly grown in the fields of X-ray and electron imaging for its unprecedented ability to achieve nano or atomic scale resolution while simultaneously retrieving…
Iterative X-ray Spectroscopic Ptychography
Huibin Chang, Ziqin Rong, Pablo Enfedaque +1
Spectroscopic ptychography is a powerful technique to determine the chemical composition of a sample with high spatial resolution. In spectro-ptychography, a sample is rastered thr…
Iterative Joint Ptychography-Tomography with Total Variation Regularization
Huibin Chang, Pablo Enfedaque, Stefano Marchesini
In order to determine the 3D structure of a thick sample, researchers have recently combined ptychography (for high resolution) and tomography (for 3D imaging) in a single experime…
Advanced Denoising for X-ray Ptychography
Huibin Chang, Pablo Enfedaque, Jie Zhang +7
The success of ptychographic imaging experiments strongly depends on achieving high signal-to-noise ratio. This is particularly important in nanoscale imaging experiments when diff…
Blind Ptychographic Phase Retrieval via Convergent Alternating Direction Method of Multipliers
Huibin Chang, Pable Enfedaque, Stefano Marchesini
Ptychography has risen as a reference X-ray imaging technique: it achieves resolutions of one billionth of a meter, macroscopic field of view, or the capability to retrieve chemica…
Partially Coherent Ptychography by Gradient Decomposition of the Probe
Huibin Chang, Pablo Enfedaque, Yifei Lou +1
Coherent ptychographic imaging experiments often discard over 99.9 % of the flux from a light source to define the coherence of an illumination. Even when coherent flux is sufficie…
