  1. G-Allows increased visualization of an area of concern
    G-Magnification
  2. O-A two step conversion that takes xrays to light to an electric signal
    O-Indirect conversion
  3. N-Dead dexel, incorrect gain colibraion and image lag are types of these artifacts
    N-Flat Panel Artifact
  4. O-Sharpness or recorded detail--is related to pixel size
    O-Spatial Resolution
  5. O-A cassettee-based system with photostimulable imaging plate

  14. I-This is the pattern in which the phosphors are scanned with a laser bean during stimulation phase of CR
    I-Raster Pattern
  15. O-Scintillator is made of, a high atomic number--absorbs xrays well
    O-Cesium Iodide
  16. G-A method used to fil in the dead pixels with info using the surrounds pixels as a guide
    G-Interpolation
  17. G-This means that electrons eventually lose energy over time if the CR plate is not processed
    G-Metastable
  18. I-permits the processed pixel values to be manipulated to adjust changes in brightness or contrast
    I-Look up Table
  19. B-made of amorphous silicon, takes light photons in indirect capture and converets to electic charge

    I-Barium Flurohalide "doped" with europium activators
  23. I-A step that occures after IR exposure that assigns a value to each pixel relative tot he energy it received
    I-Quantization
  24. G-the physical distance between pixels
    G-Pixel Pitch
  25. B-Prevents light from erasing data on imaging plate or leaking through backing
    B-Reflective Layer of CR plate
  26. G-converts the analog electronic signal into a digital signal
    G-ADC
  27. G-The color of the laser beam that frees trapped electrons during stimulation phase

  34. 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
  35. N-Scatter fog, collimation errors, prostheses within the image, barium bolus in the image
    N-Types of Pre-Processing Errors
  36. N-If a 2nd image is taken before the detector release all the singla from previous image, a faint image of previous exposure may be visible
