Radiology Concepts and Equipment
Across
- 1. Controls the quality and contrast of an image.
- 6. Longer wavelengths have ____ energy than shorter wavelengths.
- 8. The most common x-ray machine in large animal medicine is portable with a ___-________ anode.
- 10. Any form of light has electromagnetic energy is _______ energy.
- 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.
- 13. The movement of photon in a wave, measured from from peak/crest to peak with one trough (bottom.
- 15. One peak/crest and one trough/bottom, measured in oscillations per second / Hertz.
- 16. The X-ray tube head has a casing of this type of metal to prevent radiation from leaking.
- 18. Acronym for digital image and communications in medicine.
- 20. X-rays travel at the speed of _____ in a vacuum.
- 22. X-ray photons are electrically _______ and are not affected by electricity or magnetic fields.
- 23. The major source of radiation for the patient. (2 words)
- 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.
Down
- 2. Little packets of energy that travel in waves.
- 3. Anodes have a ________ charge.
- 4. The cathode consists of 2 filaments like a light bulb, made of thoriated _______.
- 5. The major source of radiation for the technician.
- 7. Variation of the intensity of X-rays emitted by the anode depending on the direction of emission along the anode-cathode axis, can be used to advantage when taking x-rays of patients with different thicknesses of tissues. (3 words)
- 9. Controls kVp.
- 11. When electrons are "boiled off" the filament, this is _________ Emission.
- 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.
- 17. Height/power of a photon's wave.
- 19. Shorter wavelengths have ____ energy than longer wavelengths.
- 21. Place to put patient to obtain a radiographic exposure, contains the grid.
- 25. Controls the quantity of the radiation.
