6.3 Verifying the exact operation of the AEC
Make an exposure using AEC. Make sure the film has the same sensitivity as the
film used for calibration during installation. Set 80kV and beam current that result in
radiation period longer than 50ms and shorter than 1s. Place a 15cm water phantom
in the radiation’s path.
After development compare this film to the film made during calibration. The optical
density can only deviate by 0.15 between the two films.
Selecting the correct screen type on the control panel in AEC mode
is extremely important, because when determining the required
dosage, the generator takes into account the selected film / screen
sensitivity as well.
