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