A method of copying X-ray films
The British Journal of Radiology, 1970Abstract A film-copying system using diazo-sensitised film developed to match the contrast requirements of medical radiography is reported. Processing is simple and rapid and can be carried out in daylight. Examples of copied radiographs are illustrated.

X-ray focusing methods for X-ray absorption spectroscopy
2022X-ray focusing methods for X-ray absorption spectroscopy (XAS) are an essential but controversial endeavour, as XAS was devised as a way to average out chemical environment effects over large numbers of atoms. However, focusing becomes necessary when one attempts to study speciation over essential but minute spatial phases, extrapolating the method ...

Roentgen discovered X-rays in 1895 and within a few years reported several of their basic properties. Among these properties are the following: 1. X-rays travel in straight lines and with the speed of light. 2. X-rays are not charged particles. 3.

Materials and Methods of X-Ray Protection
Radiology, 1946The object in planning x-ray protection for any installation is to reduce the x-ray intensity at all positions where personnel will be stationed to a value such that no one will receive more than 0.1 r during any 24-hour period. No hard and fast rules need be laid down for accomplishing this; the methods to be used are best left to the ingenuity of ...

X-ray beam induced current method at the laboratory x-ray source
Review of Scientific Instruments, 2011The x-ray beam induced current method (XBIC) is realized on the laboratory x-ray source using the polycapillary x-ray optics. It is shown that rather good images of grain boundaries in Si can be obtained by this method. The parameters of x-ray beam are estimated by the simulation of Schottky diode image.

Phase analysis of high temperature decomposition products of kaolinite are of considerable interest to the mineralogists as well as to ceramic technologists. X-ray is one of the most important tools and is used extensively for investigation of phase transformation behaviors of kaolinite during heating.

The Direct Methods of X-ray Crystallography
Science, 1986The electron density function ρ(r) in a crystal determines its diffraction pattern, that is, both the magnitudes and phases of its x-ray diffraction maxima, and conversely. If, however, as is always the case, only magnitudes are available from the diffraction experiment, then the density function ρ(r) cannot be recovered.

This chapter aims to review various techniques that utilize X-rays for probing molecular and supramolecular structure, in addition to discussing the instrumental aspects that are characteristic for each method. X-rays can be produced by deceleration of electrons and/or transitions in the inner orbital electrons of atoms.

A factorization method for the 3D X-ray transform
Inverse Problems, 1995The author considers the inversion of the three-dimensional (3D) x-ray transform with a limited data set containing the line integrals which have two intersections with the lateral surface of a truncated cylinder. This problem models reconstructions for a multi-ring positron scanner operated in the ``three-dimensional'' acquisition mode which has been ...
