  2. Dental radiography - Wikipedia

    en.wikipedia.org/wiki/Dental_radiography

    Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities.. A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor.

  3. Panoramic radiograph - Wikipedia

    en.wikipedia.org/wiki/Panoramic_radiograph

    A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw.It shows a two-dimensional view of a half-circle from ear to ear. Panoramic radiography is a form of focal plane tomography; thus, images of multiple planes are taken to make up the composite panoramic image, where the maxilla and mandible are in the focal trough and the structures that are superficial and ...

  4. Radiography - Wikipedia

    en.wikipedia.org/wiki/Radiography

    Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object.Applications of radiography include medical ("diagnostic" radiography and "therapeutic radiography") and industrial radiography.

    en.wikipedia.org/wiki/X-ray_binary

    Artist's impression of an X-ray Binary. X-ray binaries are a class of binary stars that are luminous in X-rays.The X-rays are produced by matter falling from one component, called the donor (usually a relatively common main sequence star), to the other component, called the accretor, which is either a neutron star or black hole.

    In the mid-1940s radio observations revealed a radio corona around the Sun. [13] After detecting X-ray photons from the Sun in the course of a rocket flight, T. Burnight wrote, "The sun is assumed to be the source of this radiation although radiation of wavelength shorter than 4 Å would not be expected from theoretical estimates of black body ...

    en.wikipedia.org/wiki/Sunlight

    As a result, the photosphere of the Sun does not emit much X radiation (solar X-rays), although it does emit such "hard radiations" as X-rays and even gamma rays during solar flares. [14] The quiet (non-flaring) Sun, including its corona, emits a broad range of wavelengths: X-rays, ultraviolet, visible light, infrared, and radio waves. [15]

    Astronomers think our sun will meet a similar fate one day. It will shed its outer gas layers and eventually fade into a white dwarf star.. The bad news is that Earth will likely get fried during ...

  9. Hyperdontia - Wikipedia

    en.wikipedia.org/wiki/Hyperdontia

    Supernumerary teeth may be detected by taking two different dental X-rays at different angles. Examples of this may be an intra-oral X-ray (one that is taken inside the mouth) and a panoramic radiograph. However, these X-rays are 2D and therefore do not accurately portray the 3D view of the teeth. [2]
