Collimation
On modalities that support automatic collimation, the collimation settings are
applied automatically and must be checked by the user.
Ralco collimators may limit the X-ray field. To overrule the limitation, the
collimator must be unlocked using a key and the collimation must be applied
manually.
Exposure Sequence
Procedure:
1. Set the mAs value to the indicative value for the first exposure level.
2. Make three exposures.
The DR Calibration Tool may instruct to increase or decrease the mAs
setting to reach the required exposure level.
3. Adjust the mAs value for the second exposure level. The second exposure
level is approximately at 2/3 of the first exposure level.
4. Make three exposures.
5. Adjust the mAs value for the third exposure level. The third exposure level
is approximately at 1/3 of the first exposure level.
6. Make three exposures.

The collimation area should extend at least 1.5
cm on each side of the DR Detector.
Note: If the exposure settings used for a previous calibration are
known, use these settings.
