X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10^-8 to 10^-12 metre. The passage of X-rays through materials, including biological tissue, can be recorded. Thus, analysis of X-ray i
III.A.1.cX-Ray source Two types of X-ray sources are currently used in X-rayCT. The most simple type is the fixed-anode X-ray tube, in which the anode is cooled by oil and is continuously energized. A typical focal spot size of this type is about 2mm×16mm on a 20° angletungs...
Optical transient surveys have led to the discovery of dozens of stellar tidal disruption events (TDEs) by massive black hole in the centers of galaxies. Despite extensive searches, X-ray follow-up observations have produced no or only weak X-ray detecti

X-ray holography with single X-ray free-electron laser pulses has now enabled a quasi-instantaneous high resolution structural probe with contrast proportional to the electron density of the object. In this work, we demonstrate cone-beam holographic flash imaging of laser-induced cavitation bubbles ...
The incident beam of X-rays is partly absorbed, partly scattered, and the rest is transmitted unmodified through the specimen. The scattering occurs due to interaction between the incident X-ray beam with the electrons in the material, and the diffracted X-rays interact with each other to cause...
ray backligther source with a Lithium Fluoride detector, characterized by its large dynamic range. A spatial resolution of 2 µm over a field of view greater than 2 mm2is reported. The platform was benchmarked with both an X-ray free electron laser (XFEL) and an X-ray source ...
Recently, we have presented an X-ray tailored eosin-based staining method, which interacts with the cell cytoplasm17. Within this work, we introduce a hematein-based staining method, which has been explicitly developed for CT allowing now for a direct 3D visualization of cell nuclei within soft...
High energy X-ray imaging has unique advantage over conventional X-ray imaging, since it enables higher penetration into materials with significantly reduced radiation damage. However, the absorption contrast in high energy region is considerably low due
A structured approach to chest X-ray interpretation with examples of pathology you'll be expected to recognise in an OSCE.
