Across
- 1. added to the names of those projections in which the central ray passes(not parallel) to one of the three major directional axes through the body part
- 5. Ensure that the emulsion stays attached to the base
- 7. The radiation dose to any creature must be (5 LETTER ACRONYM)
- 9. Structure or appearance that is not normally present on the radiograph and is produced by artificial means
- 11. Consists of a tungsten “target” upon which the electrons (now photons of energy) are focused
- 13. special heat-resistant glass enclosure that houses a cathode and an anode
- 14. process by which intensifying screens react to the incoming radiation
- 15. Filaments carefully positioned opposite the outer rim of the anode in a small cup-shaped device called the
- 17. Controls the size of the X-ray beam and prevents it from spreading wider than necessary
- 19. Figured out what made the plate glow, how to prevent it from glowing, and how to categorize the rays that caused the glow
- 20. the number of waves passing a given point per given unit of time
Down
- 2. Transmit light evenly through a specially produced glass in order to visualize and interpret radiographic images
- 3. the tracing of the crests and troughs of a wave
- 4. the outside edge or shadow where the film has been imperfectly collimated
- 6. the portion of the x-ray image that is sharp and clearly collimated
- 8. SHOWS UP AS BALL OR TREE LIGHTNING ON AN X-RAY
- 10. an instantaneous reaction that lasts exactly as long as the phosphor is stimulated
- 12. greater number of shades of gray in the image
- 16. intensity of the radiation is greater on the cathode side than on the anode side
- 18. the smallest quantity of any type of electromagnetic radiation
