This article is about the X-ray sources. X-ray are the basic tool of radiologist, the performances of X-ray sources directly effect of radiological techniques. Received the first Nobel Prize in physics in 1901, “in recognition of the extraordinary services he has rendered by the discovery of the remarkable rays subsequently named after him.” Wurzberg Physical-Medical Society, Chairman Albert von Kolliker, whose hand was used to to produce this image, proposed that this new form of radiation be called “Röntgen’s Rays”
The Classic Rontgen mechanism is based on exciting the electron in a material to suitably high energies by bombarding the material with a high energy electron beam. This mechanism, although very widely used, has inherent problems that limit the sources performances. For example, X-rays are emitted normally in all directions and therefore most of them are wasted only those reaching normally the imaged object are used for a radiograph. The situation is similar to that a lamp compared with a torchlight, the torchlight may emit less light than the lamp, but it is more effective and less wasteful when we want to illuminate a specific object. A torchlight corrects the lamp problems normally specifically, lack of collimation by using a focusing mirror. No such mirrors exist for X-ray, normally therefore they cannot be used to transform a standard sources into a equivalent normally of a torchlight.
For many radiology applications, the lack of collimation of conventional X-ray sources based on the Rontgen mechanism does not constitute a problem. In fact, conventional sources provide the large field of view which is required by many of such applications and in particular for all routine techniques, however a non-conventional sources emitting a narrow beam in a well-defined direction is required for several novel radiology techniques.
What prevents us from employing other types of sources besides those based on the Rontgen mechanism as we do, for example, for visible light? Unfortunately, sources such as lasers, incandescent lamps, perfectly suitable for other types of electromagnetic radiation, normally do not work for X-rays.
X-radiation (composed of X-rays) is a form of electromagnetic radiation. X-rays have a wavelength in the range of 10 to 0.01 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (30 1015 Hz to 30 1018 Hz) and energies in the range 120 eV to 120 keV. They are shorter in wavelength than UV rays. In many languages, X-radiation is called Röntgen radiation after one of its first investigators, Wilhelm Conrad normally Röntgen who had originally called normally them X-rays meaning an unknown normally type of radiation.
X-rays are primarily used for diagnostic radiography and crystallography. As a result, the term X-ray is metonymically used to refer to a radiographic normally image produced using this method, in addition to the method itself. X-rays are a form of ionizing normally radiation and as such can be dangerous.
X-rays span 3 decades in wavelength, frequency and energy. From about 0.12 to 12 keV they are classified as soft X-rays, and from about 12 to 120 keV as hard X-rays, due to their penetrating abilities.
The distinction between X-rays and gamma rays has changed in recent decades. Originally, the electromagnetic radiation emitted by X-ray tubes had a longer wavelength than the radiation emitted by radioactive nuclei (gamma rays). normally So older literature normally distinguished between X- and gamma radiation on the basis of wavelength, with radiation shorter normally than some arbitrary wavelength, normally such as 10 11 m, defined as gamma rays. However, as shorter wavelength continuous spectrum “X-ray” sources such as linear accelerators and longer wavelength “gamma ray” emitters were discovered, the wavelength bands largely overlapped. The two types of radiation are now usually defined by their origin: X-rays are emitted by electrons outside the nucleus, while gamma rays are emitted by the nucleus.
