    G-Magnification
  2. I-A step that occures after IR exposure that assigns a value to each pixel relative tot he energy it received
    I-Quantization
  3. B-acts as a gride of tiny switches, activates each pizel to send signal to the compouter
    B-Thin-Film- Transistor
  4. G-What the photodiode is made of in indirect conversion

  18. B-made of amorphous silicon, takes light photons in indirect capture and converets to electic charge
    B-photodiode
  19. 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
    N-Image lag
  20. G-This means that electrons eventually lose energy over time if the CR plate is not processed
    G-Metastable
  21. O-Sharpness or recorded detail--is related to pixel size
    O-Spatial Resolution
