  1. 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
  2. I-This is the pattern in which the phosphors are scanned with a laser bean during stimulation phase of CR
    I-Raster Pattern
  3. I-What the phosphor layer of the CR plate is made of
    I-Barium Flurohalide "doped" with europium activators
  4. O-Sharpness or recorded detail--is related to pixel size
    O-Spatial Resolution
  5. B-Prevents light from erasing data on imaging plate or leaking through backing
    B-Reflective Layer of CR plate
  6. I-What photoconductor is made out of used in direct conversion
    I-Amorphus Selenium
  7. I-Window Level
  8. I-When you have a high fill factor, you get this
    I-High Spatial Resolution
  9. G-A comparison of the area that senses the electrical singal/light compared to area that does not
    G-Fill Factor
  10. N-Insulates imaging plate from handling trauma
    N-Protective (Supportive) layer of CR Plate
  11. O-A cassettee-based system with photostimulable imaging plate
    O-Computed Radiography
  12. N-Converts digital singal back to analog so image can be viewed on the montior
    N-DAC
  13. O-Absorb x-rays and cause an electrical charge used in direct conversion
    O-Photoconductors
  14. I-What occurs before we see the iamge. Also called image acquisition processing
    I-Pre processing
  15. B-changes black areas of the image to white and white areas to black
    B-Image Inversion
  16. G-the physical distance between pixels
    G-Pixel Pitch
  17. G-converts the analog electronic signal into a digital signal
    G-ADC
  18. N-used in indirect to convert xrays to visbile light
    N-Scintillator
