5.14 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 29.
To enable/disable ALC:
1. Bring up the OSD main menu.
2. Navigate to the Configuration > Calibration > Ambient Light menu.
3. Enter the Ambient Light Compensation submenu.
4. Select Enabled/Disabled as desired and confirm.

If you select Native, the native panel behavior will
not be corrected.
These are gamma functions that are shifted to take
into account the non-zero luminance of an LCD
panel when driven with a "black" signal. They are
especially useful in CT applications to improve the
perception of low Hounsfield values.
DICOM (Digital Imaging and Communications
in Medicine) is an international standard that
was developed to improve the quality and
communication of digital images in radiology.
In short, the DICOM display function results in
more visible grayscales in the images. Barco
recommends selecting the DICOM display function
for most medical viewing applications.
This display function will be automatically selected
when display functions are defined by MediCal
QAWeb.
Select one of these display functions in case the
display is to replace a CRT display with a gamma
of 1.8 or 2.2 respectively.
