and re-enter the observed density value. Continue until the mea-
sured density value equals the Target Gray Level setting to within
acceptable limits. When it does, press Confirm button.
c. The system advances to Calibration Wizard - 60kVp 10cm Calibration
screen.
7. Repeat the previous steps for the 60, 80, 100, 110, 120, and, if 150 kV
system, 130 and 140 kVp calibration points, placing the specified thick-
ness of acrylic in the x-ray beam as indicated on the Calibration Wizard -
AEC kVp Calibration screen for each kV calibration point, until all the
observed density values are within required range.
8. This completes AEC calibration for this particular Receptor/Film Screen.
Repeat AEC calibration procedures for all additional Receptor/Film
Screens that will be used with the system.
9. Verify AEC calibration by taking several exposures in AEC mode and
checking the resulting density value. If necessary, repeat AEC calibration
procedure to further adjust AEC accuracy.
