Across
  1. 1. occur by chance and may occur without a threshold level dose, most common effect cancer
  2. 3. uses thickness of area to penetrate the tissue
  3. 6. partner to the cathode, consists of tungsten target upon which electrons are focused
  4. 9. has large filament for large body parts and small filament for detailed work
  5. 12. foreshortening or elongation of a body part due to angulation
  6. 15. quantity of the radiation, effects density
  7. 16. used to measure the anatomical area of interest so that exposures can be made
  8. 17. heat-resistant glass enclosure that houses a cathode and a anode
  9. 19. intensity of the radiation is greater on the cathode side than on the anode side
  10. 20. withstand high temperature without melting
Down
  1. 2. cathode temperature quickly rises and electrons "boiled off" in reaction called
  2. 4. unit of pure energy travel in waves at the speed of light
  3. 5. noticeable in short-term, erythema most common effect
  4. 7. as low as reasonably achievable
  5. 8. set of lead shutters which can be adjusted to position the beam
  6. 10. exposure is reduced by the square of the distance from the patient
  7. 11. quality of the radiation, effects contrast in the image
  8. 13. created by the photon stream outside the actual focal spot
  9. 14. portion of the xray image that is sharp and clearly collimated
  10. 18. is the outside edge or shadow where the film has been imperfectly collimated
