Across
  1. 3. Any unwanted exposure on a radiographic image
  2. 8. Range of exposure intensities that an image receptor can respond to and acquire image data
  3. 9. Image that is considered visible
  4. 12. The difference between the x-ray photons that are absorbed photoelectrically and those that penetrate the body
  5. 13. Created by passing an x-ray beam through the patient and interacting with an image receptor
  6. 15. The x-ray photons removed from the x-ray beam as a result of the uptake of their energy by body tissues
  7. 17. Another term for exit radiation
  8. 18. Scattering that results from the loss of some energy of the incoming photon when it ejects an outer-shell electron from a tissue atom
  9. 20. The electron ejected from an atom during a photoelectric interaction
  10. 24. The incoming x-ray photon passes through the anatomic part without any interaction with the anatomic structures
Down
  1. 1. Compactness of the cellular structures
  2. 2. The electron ejected from an atom during a Compton scattering event
  3. 4. The attenuated x-ray beam leaves the patient and is composed of both transmitted and scattered radiation
  4. 5. The incoming photons are not absorbed but instead lose energy during interactions with the atoms composing the tissue
  5. 6. Total absorption of the incident photon by ejecting an inner-shell electron
  6. 7. The ability to remove or eject electrons
  7. 9. Combination of rows and columns (array) of pixels
  8. 10. A device that receives the radiation leaving the patient
  9. 11. The penetrating ability of the x-ray beam
  10. 14. Reduction in the energy or number of photons in the primary x-ray beam after it interacts with anatomic tissue
  11. 16. An interaction that occurs with low-energy x-rays, typically below the diagnostic range
  12. 19. Smallest component of a matrix that is represented as a single brightness level on a computer monitor
  13. 21. Image that is considered invisible
  14. 22. Dynamic imaging that provides imaging of the movement of internal structure
  15. 23. Number of bits that determines the amount of precision in digitizing the analog signal and the number of shades of gray that can be displayed on an image
