Ptychographic X-ray computed tomography at a high-brilliance X-ray source.

Optics Express, 2019
Ptychographic X-ray computed tomography is a phase-contrast imaging technique capable of retrieving three-dimensional maps of the index of refraction of the imaged volumes with nanometric resolution.

X-ray refraction distinguishes unprocessed powder from empty pores in selective laser melting Ti-6Al-4V

Materials Research Letters, 2018
For the first time, X-ray refraction techniques are proven for the identification of void formation in Ti-6Al-4V parts produced by selective laser melting.

Toward optimal X-ray flux utilization in breast CT [PDF]

, 2011
A realistic computer-simulation of a breast computed tomography (CT) system and subject is constructed. The model is used to investigate the optimal number of views for the scan given a fixed total X-ray fluence.

Comparison of different sources for laboratory X-ray microscopy

, 2012
This paper describes the setup of two different solutions for laboratory X-ray microscopy working with geometric magnification. One setup uses thin-film transmission targets with an optimized tungsten-layer thickness and the electron gun and optics of an

Neural networks for calibration tomography [PDF]

Artificial neural networks are suitable for performing pattern-to-pattern calibrations. These calibrations are potentially useful for facilities operations in aeronautics, the control of optical alignment, and the like.
