  2. X-ray tube - Wikipedia

    en.wikipedia.org/wiki/X-ray_tube

    An X-ray tube is a vacuum tube that converts electrical input power into X-rays. [1] ... an electrostatic machine. [citation needed] Crookes tubes were unreliable. As ...

  3. X-ray machine - Wikipedia

    en.wikipedia.org/wiki/X-ray_machine

    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.

  4. Crookes tube - Wikipedia

    en.wikipedia.org/wiki/Crookes_tube

    Crookes X-ray tube from around 1910 Another Crookes x-ray tube. The device attached to the neck of the tube (right) is an "osmotic softener". When the voltage applied to a Crookes tube is high enough, around 5,000 volts or greater, [16] it can accelerate the electrons to a high enough velocity to create X-rays when they hit the anode or the glass wall of the tube.

  5. Shoe-fitting fluoroscope - Wikipedia

    en.wikipedia.org/wiki/Shoe-fitting_fluoroscope

    The x-ray tube was removed to render the apparatus harmless before being put on public display, due to the possible risk of radiation burn or other health problems if it were switched on. The risk of radiation burns to extremities was known since Wilhelm Röntgen 's 1895 experiment, but this was a short-term effect with early warning from ...

    A 200 kV orthovoltage X-ray tube used for radiation therapy, 1938. Orthovoltage X-ray machines are similar to diagnostic (radiography) X-ray machines, except that higher voltages are used and the X-ray tube is longer, to prevent the high voltages from arcing across the tube. ICD10 =

  7. Operation of computed tomography - Wikipedia

    en.wikipedia.org/wiki/Operation_of_computed...

    In conventional CT machines, an X-ray tube and detector are physically rotated behind a circular shroud (see the image above right). An alternative, short lived design, known as electron beam tomography (EBT), used electromagnetic deflection of an electron beam within a very large conical X-ray tube and a stationary array of detectors to achieve very high temporal resolution, for imaging of ...

    en.wikipedia.org/wiki/X-ray

    Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.

  9. Megavoltage X-rays - Wikipedia

    en.wikipedia.org/wiki/Megavoltage_X-rays

    Megavoltage X-rays are produced by linear accelerators ("linacs") operating at voltages in excess of 1000 kV (1 MV) range, and therefore have an energy in the MeV range. The voltage in this case refers to the voltage used to accelerate electrons in the linear accelerator and indicates the maximum possible energy of the photons which are subsequently produced. [1]
