Across
  1. 2. Columns and rows of pixels
  2. 4. Smallest element in a digital image
  3. 7. The efficiency of an IR in converting the x-rays it receives into a quality image
  4. 8. The level of contrast resolution compared to the amount of noise in a digital image
  5. 9. The amount of radiation the IR received
  6. 11. When you view your image on film
  7. 12. Blackens out the white collimation borders
  8. 13. Performed by the Radiologist or Technologist
  9. 17. Controls brightness
  10. 20. Number of bits within a pixel
  11. 21. The strength of the radiation exposure compared to the amount of noise in a digital image
  12. 23. Your histogram is compared to the LUT and if it's not a match it will apply the ideal histogram to the image
  13. 24. The invisible image
  14. 25. Computer's language
  15. 27. The ability to differentiate between two nearby parts of an image
  16. 28. The ability of an IR to accurately capture the range of photon intensities
Down
  1. 1. Happens before the image is displayed
  2. 3. Distance from the center of one pixel to the next pixel
  3. 5. The range of exposures that should be used to produce an image
  4. 6. The difference between target exposure and actual exposure
  5. 8. A system’s ability to display more shades of gray
  6. 10. Used when anatomy is too large to fit on one IR
  7. 14. Why film was so expensive
  8. 15. Number of pixels per unit area
  9. 16. A graphic representation of a data set
  10. 18. A measure of the system's ability to display the contrast of anatomic objects of different sizes
  11. 19. The ideal histogram for a given projection
  12. 22. Controls contrast
  13. 26. Allows for additional information to be added to an image
