Industrial radiography is a modality of non-destructive testing that uses ionizing radiation to inspect materials and components with the objective of locating and quantifying defects and degradation in material properties that would lead to the failure of engineering structures. It plays an important role in the science and technology needed ...
The Therac-25 was designed as a machine controlled by a computer, with some safety mechanisms switched from hardware to software as a result. AECL decided not to duplicate some safety mechanisms, and reused modules and code routines from the Therac-20 for the Therac-25. The first prototype of the Therac-25 was built in 1976 and was put on the ...
An X-ray generator generally contains an X-ray tube to produce the X-rays. Possibly, radioisotopes can also be used to generate X-rays. [1]An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.
From the early 1920s through to the 1950s, X-ray machines were developed to assist in the fitting of shoes [61] and were sold to commercial shoe stores. [62] [63] [64] Concerns regarding the impact of frequent or poorly controlled use were expressed in the 1950s, [65] [66] leading to the practice's eventual end that decade. [67]
The second improvement to the facilities, now named the "Extremely Brilliant Source" (ESRF-EBS), took place between 2018 and 2020. and again improved its X-ray power by a factor of 100, [5] or 10,000 billion more powerful than X-rays used in the medical field. It became the first fourth-generation high-energy synchrotron in the world.
X-ray optics is the branch of optics that manipulates X-rays instead of visible light.It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and X-ray astronomy.
X-ray detector. Acquisition of projectional radiography, with an X-ray generator and an imaging detector. X-ray detectors are devices used to measure the flux, spatial distribution, spectrum, and/or other properties of X-rays. Detectors can be divided into two major categories: imaging detectors (such as photographic plates and X-ray film ...
