X-rays are capable of penetrating some thickness of matter. Medical x-rays are produced by letting a stream of fast electronscome to a sudden stop at a metal plate; it is believed that x-rays emitted by the Sun or stars also come from fast electrons. The images produced by x-rays are due to the different absorption rates of different tissues. Calci...
On 8 Nov 1895, Wilhelm Conrad Röntgen (accidentally) discovered an image cast from his cathode ray generator, projected far beyond the possible range of the cathode rays(now known as an electron beam). Further investigation showed that the rays were generated at the point of contact of the cathode ray beam on the interior of the vacuum tube, that t...
William Coolidge invented the X-ray tube popularly called the Coolidge tube. His invention revolutionized the generation of X-rays and is the model upon which all X-ray tubes for medical applications are based.
A breakthrough in tungsten applications was made by W. D. Coolidge in 1903. Coolidge succeeded in preparing a ductile tungsten wire by doping tungsten oxide before reduction. The resulting metal powder was pressed, sintered and forged to thin rods. A Very thin wire was then drawn from these rods. This was the beginning of tungsten powder metallurgy...
A computed tomography scan or CAT-scan uses x-rays to create images of the body. However, a radiograph (x-ray) and a CAT-scan show different types of information. An x-ray is a two-dimensional picture and a CAT-scan is three-dimensional. By imaging and looking at several three-dimensional slices of a body (like slices of bread) a doctor could not o...

Dec 7, 2020 · The two sequences were outwardly very simple. People on their way to catch the underground trains walked through a giant X-ray machine. The length of the machine was approximately 20 feet and one entire wall acted as a screen. Guards sit in front of this wall and watch the commuters, looking for tell-tale signs of weapons.

Mar 6, 2016 · Manufacturers of each type of digital system specify the expected range of x-ray exposure sufficient to produce a quality image. A numeric value (exposure indicator) is displayed on the processed image to indicate the level of x-ray exposure received (incident exposure) to the digital IR. It is important for the radiographer to consider the ...
The voltages used in diagnostic X-ray tubes range from roughly 20 kV to 150 kV and thus the highest energies of the X-ray photons range from roughly 20 keV to 150 keV. [ 90 ] Both of these X-ray production processes are inefficient, with only about one percent of the electrical energy used by the tube converted into X-rays, and thus most of the electric power consumed by the tube is released ...
The X-ray housing is turned by 90° for a chest radiograph. An X-ray machine is a device that uses X-rays for a variety of applications including medicine, X-ray fluorescence, electronic assembly inspection, and measurement of material thickness in manufacturing operations. In medical applications, X-ray machines are used by radiographers to ...
