  1. O-Absorb x-rays and cause an electrical charge used in direct conversion
    O-Photoconductors
  2. G-A method used to fil in the dead pixels with info using the surrounds pixels as a guide
    G-Interpolation
  3. I-When you have a high fill factor, you get this
    I-High Spatial Resolution
  4. I-permits the processed pixel values to be manipulated to adjust changes in brightness or contrast
    I-Look up Table
  5. O-Scintillator is made of, a high atomic number--absorbs xrays well
    O-Cesium Iodide
  6. B-A one step process where x-rays are absorebed by a photoconductor
    B-Direct conversion
  7. B-acts as a gride of tiny switches, activates each pizel to send signal to the compouter
    B-Thin-Film- Transistor
  8. G-What the photodiode is made of in indirect conversion
    G-Amporhous Silicon
  9. G-Allows increased visualization of an area of concern
    G-Magnification
  10. G-converts the analog electronic signal into a digital signal
    G-ADC
  11. 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
  12. I-What occurs before we see the iamge. Also called image acquisition processing
    I-Pre processing
  13. I-This is the pattern in which the phosphors are scanned with a laser bean during stimulation phase of CR
    I-Raster Pattern
  14. N-Scatter fog, collimation errors, prostheses within the image, barium bolus in the image
    N-Types of Pre-Processing Errors
  15. I-What photoconductor is made out of used in direct conversion
    I-Amorphus Selenium
  16. G-This means that electrons eventually lose energy over time if the CR plate is not processed
    G-Metastable
  17. G-the physical distance between pixels
    G-Pixel Pitch
  18. N-Converts digital singal back to analog so image can be viewed on the montior
    N-DAC
  19. B-Prevents light from erasing data on imaging plate or leaking through backing
    B-Reflective Layer of CR plate
  20. I-A step that occures after IR exposure that assigns a value to each pixel relative tot he energy it received
