  1. O-Sharpness or recorded detail--is related to pixel size
    O-Spatial Resolution
  2. N-Scatter fog, collimation errors, prostheses within the image, barium bolus in the image
    N-Types of Pre-Processing Errors
  3. O-The color of light emitted during photostimulable luminescence this is the light is directly porportional to the amount of radiation the plate absorbed during exposure
    O-Blue
  4. O-Adding text or markers to the image
    O-Annotation

    I-Amorphus Selenium
  6. I-Window Level
  7. I-When you have a high fill factor, you get this
    I-High Spatial Resolution
  8. N-Dead dexel, incorrect gain colibraion and image lag are types of these artifacts
    N-Flat Panel Artifact
  9. B-what we can do to the image after it is displayed
    B-Post processing
  10. I-permits the processed pixel values to be manipulated to adjust changes in brightness or contrast
    I-Look up Table
  11. N-used in indirect to convert xrays to visbile light
    N-Scintillator
  12. B-Active component that holds photostimulable phosphors and traps e- during exposure
    B-Phosphor Layer of CR Plate
  13. O-A two step conversion that takes xrays to light to an electric signal
    O-Indirect conversion
  14. I-What the phosphor layer of the CR plate is made of
    I-Barium Flurohalide "doped" with europium activators
  15. B-made of amorphous silicon, takes light photons in indirect capture and converets to electic charge
    B-photodiode
  16. G-What the photodiode is made of in indirect conversion
    G-Amporhous Silicon
  17. I-A step that occures after IR exposure that assigns a value to each pixel relative tot he energy it received
    I-Quantization
