5.18 Ambient Light Compensation (ALC)
About ALC
Ambient Light Compensation (ALC) can only be enabled on your display when the DI-
COM display function is selected. Therefore, please refer to "Display functions", page
25 to correctly set the display function.
When ALC is enabled, the DICOM display function will be recalculated taking a preset ambient light cor-
rection value into account. This value is determined by the selected reading room. Therefore, it is also
important to select a realistic reading room when enabling ALC. This can be done by following the instruc-
tions in "Reading rooms", page 26.
To enable/disable ALC:
1. Bring up the OSD main menu.
2. Navigate to the
Con

About reading rooms
Reading rooms can only be selected when the DICOM display function is selected.
Therefore, please refer to "Display functions", page 25 to correctly set the display
function.
The American Association of Physicists in Medicine (AAPM) composed a list of pre-de
fi
ned reading rooms.
Each of these reading rooms are de
fi
ned by following parameters:
•
the maximum light allowed in this type of room
•
the preset ambient light correction value for this reading room
These parameters are stored in your display and determine the preset ambient light correction value to
take into account to recalculate the DICOM display function when Ambient Light Compensation (ALC) is
enabled. Please refer to "Ambient Light Compensation (ALC)", page 26 to enable ALC.
