  1. 1. Controls the quality and contrast of an image.
  2. 6. Longer wavelengths have ____ energy than shorter wavelengths.
  3. 8. The most common x-ray machine in large animal medicine is portable with a ___-________ anode.
  4. 10. Any form of light has electromagnetic energy is _______ energy.
  5. 12. A form of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space.
  6. 13. The movement of photon in a wave, measured from from peak/crest to peak with one trough (bottom.
  7. 15. One peak/crest and one trough/bottom, measured in oscillations per second / Hertz.
  8. 16. The X-ray tube head has a casing of this type of metal to prevent radiation from leaking.
  9. 18. Acronym for digital image and communications in medicine.
  10. 20. X-rays travel at the speed of _____ in a vacuum.
  11. 22. X-ray photons are electrically _______ and are not affected by electricity or magnetic fields.
  12. 23. The major source of radiation for the patient. (2 words)
  13. 24. Metal shutters to block photon path (absorbs them) to restrict the size of the x-ray beam and reduce the amount of scatter radiation.

  8. 14. The glass tube enclosure in the X-ray tube head provides a ______, preventing particles in air from interfering with the paths of electrons and photons.
  9. 17. Height/power of a photon's wave.
  10. 19. Shorter wavelengths have ____ energy than longer wavelengths.
  11. 21. Place to put patient to obtain a radiographic exposure, contains the grid.
  12. 25. Controls the quantity of the radiation.
