Demonstration of X-ray Holography with an X-ray Laser
Science, 1987An x-ray hologram was made by means of an x-ray laser and a laser-quality near normal incidence x-ray mirror. The high brightness and large coherence lengths of x-ray lasers now offer the potential for in vitro three-dimensional high-resolution holographic images of dynamically varying biological microstructures.

Owing to the short wavelengths of X-radiation X-ray microscopes allow higher resolution than optical microscopes. In contrast to electron microscopes, X-radiation can be used to study relatively thick aqueous specimens in their natural environment. X-ray microscopes require intense X-radiation, which is best provided by electron storage rings, as well ...

X-rays are an electromagnetic radiation of short wavelength, and can be produced by the sudden deceleration of rapidly moving electrons at a target material. If an electron falls through a potential difference of V volt, it acquires an energy eV electron-volt (eV), where e is the charge on an electron.

Since their discovery in 1895, X-rays have been widely used for imaging humans. Recently, they have also gained an importance in small animal imaging (SAI). Most techniques known from clinical medicine, including single- and dual-energy X-ray imaging, have been successfully ported to SAI and are the subject of this chapter.

The regulations on the handling of X rays are very similar to the regulations on standard radiation protection. The X-ray regulations in the European Union apply to those X-ray tubes and X-ray installations in which electrons are accelerated at least to 5 keV and in which they are limited to a maximum energy of 1 MeV.

The British Journal of Radiology, 1984
A costing system for radiology departments has been developed which runs on a micro-computer and can produce, for about two days' clerical work, a list of average costs for every type of X ray performed in a department. All costs, including capital and radiologists' time, are covered and the system could be used in the development of performance ...
