Very dark image

Image is too dark (black); anatomical structures cannot be seen readily; image is flat and low in contrast.

Possible causes:

  • Exposure:
    • X-ray beam energy level is producing too much radiation and overexposing the film; mAs setting too high or kVp is too high.
  • Processing:
    • Processing temperature of developer is too high.
    • Development time may be too long in manual processing.
    • The speed of the film transport system may be too slow in an automated processing system.
    • Developer solution is contaminated with fixer.
