Definium 5000 X-Ray System
Operator Manual
Shows the current SID, the recommended SID for this technique.
The alert icon indicates that the SID is not at the recommended
position. A checkmark indicates that the current SID matches the
recommended SID.
NOTE: Exposure may not be inhibited if the current SID is not the
recommended SID.
If in AEC mode, selects the ions chambers to use.
NOTE: When in AEC mode, at least one ion chamber must be
selected. Any combination of chambers is allowed.
NOTE: When in AEC mode, the body part must cover the selected
ion chambers in order to achieve the proper exposure.
Refer to
Chapter 7: Automatic Exposure Control (AEC)
information about AEC.
Adjusts the kV.
The up/down buttons on the right of the field adjust the kV by one
unit.
The buttons on the left of the field adjust the kV by 5 units.
The kVp selection range is 40-150, in1 kVp increments.
Adjusts the mA.
The mA selection is in Renard steps. The available selections are:
10, 12.5, 16, 20, 25, 32, 40, 50, 64, 80, 100, 125, 160, 200, 250, 320,
400, 500, 640.
NOTE: Not all mA and mAs selections are available at all kV settings.
If in FIXED mode, adjusts the mAs.
The mAs selection is in Renard steps. The available selections are:
0.1, 0.12, 0.16, 0.20, 0.25, 0.32, 0.40, 0.50, 0.64, 0.80, 1.0, 1.25, 1.6,
2.0, 2.5, 3.2, 4.0, 5.0, 6.4, 8.0, 10.0, 12.5, 16.0, 20.0, 25.0, 32.0, 40.0,
50.0, 64.0, 80.0, 100.0, 125.0, 128.0, 160.0, 200.0, 250.0, 256.0,
320.0, 400.0, 500.0, 512.0.
NOTE: Not all mAs selections are available at all kV settings.
If in AEC mode, shows the calculated mAs for the current kV and
mA after exposure.
