In situ X-ray area detector flat-field correction at an operating photon energy without flat illumination

open access: yesJournal of Synchrotron Radiation, 2023
Flat-field calibration of X-ray area detectors is a challenge due to the inability to generate an X-ray flat-field at the selected photon energy the beamline operates at, which has a strong influence on the measurement behavior of the detector.

Scalable and accurate multi-GPU-based image reconstruction of large-scale ptychography data

open access: yesScientific Reports, 2022
While the advances in synchrotron light sources, together with the development of focusing optics and detectors, allow nanoscale ptychographic imaging of materials and biological specimens, the corresponding experiments can yield terabyte-scale volumes ...

X-RAYS AND X-RAY DIAGNOSIS. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1897
A great discovery, great in the sense of discovering a fundamental principle or a fact profoundly modifying existing theories or hypotheses, is not infrequently found to be of most value, from the purely utilitarian standpoint, in some branch of science, or some art, other than that in which it was primarily made.

Visualization of internal 3D structure of small live seed on germination by laboratory-based X-ray microscopy with phase contrast computed tomography

open access: yesPlant Methods, 2020
Background The visualization of internal 3D-structure of tissues at micron resolutions without staining by contrast reagents is desirable in plant researches, and it can be achieved by an X-ray computed tomography (CT) with a phase-retrieval technique ...

X-ray bursts [PDF]

open access: yesInternational Astronomical Union Colloquium, 1993
An X-ray burst is a sudden increase (rise time of order seconds) of the X-ray brightness of an X-ray source, which after reaching its peak decays, generally within a minute. The sky distribution of X-ray burst sources indicates that they are galactic objects (see Fig.
