X-ray - Wikipedia. En.wikipedia An X-ray, or X-radiation, is a penetrating form of high-energy electromagnetic radiation.Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×10 16 Hz to 3×10 19 Hz) and energies in the range 124 eV to 124 keV.X-ray wavelengths are shorter than those of UV rays ...

Today’s x-ray machines produce a stream of electromagnetic radiation that interacts with an anode in an x-ray tube. The x-rays made by this interaction are then directed toward the part of the body being examined. To reduce radiation exposure, x-ray machines aim the x-rays at only the focus area.

The general formula for energy of a single photon of an electromagnetic wave such as an X-ray is given by Planck's equation: E=hν, in which energy E in Joules is equal to the the product of Planck's constant h (6.626 × 10 −34 Js) and the frequency ν (pronounced "nu") in units of s_-1 _. For a given frequency of an electromagnetic wave, you can calculate the associated X-ray energy for a ...

Tube feeding is important to maintain adequate nutrition and prevent liver problems in cats that are anorexic for at least 2 days. Tube feeding may be needed because of a mechanical problem interfering with ingestion of food or because of a systemic illness that is causing the cat to be anorexic. There are several different options for tube feeding.

In discussing the principles of accurate image projection, the source of x-ray photons is the focal spot on the anode target inside the x-ray tube within the x-ray head. The principles of accurate image projection can be summarized as follows: Principle One: X-rays Should be Emitted from the Smallest Source of Radiation as Possible.

Free Radiology Flashcards about RAD121. Studystack Cathode: The negative side of the x-ray tube; produces a thermionic cloud, conducts the high voltage to the gap between the cathode and anode, and focuses the electron stream as it heads for the anode. Cathode Assembly: Consists of the filament, focusing cup, and associated wiring. Dual Focus: A two-filament arrangement within the x-ray tube.

Apr 02, 2019 · Electromagnetic energy or electromagnetic radiation is light. It's any self-propagating energy that has an electric and magnetic field. You can draw examples of electromagnetic energy from any part of the spectrum.

Jun 06, 2016 · The good and bad of CR is that it enables digital imaging with the traditional workflow of X-ray film. With CR, like film, no synchronization to the generator is required, which had been a requirement for DR imaging.
