DX-D 25C Exposure Sequence
Modality Settings
Apply these modality settings:
Table 8: Modality settings
kV 75 kV
mAs (indicative value for first ex-
posure level)
12.5 mAs
mAs (indicative value for second
exposure level)
8 mAs
mAs (indicative value for third ex-
posure level)
4 mAs
Focus large focus
SID Use the (average) SID for normal operation.
Position If the DR Detector is used in a fixed position, use the same
position for calibration.
If the DR Detector is used in different positions, perform the
calibration with the short side of the DR Detector parallel to
the axis of the X-ray tube.
Grid Remove the grid.
Filtration No filtration.
Collimation 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.
On modalities that support automatic collimation, the collimation settings are applied automatical-
ly and must be checked by the user.
