5.15 Amb ient 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
26 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 ins
truc-
tions in "Reading rooms", page 27.
To enable/disable A LC:
1. Bring up the OSD main menu.
2. Navigate to the Co nfiguration > Calibration > Ambient Light menu.
3. Enter the Ambient Light Compensation submenu.
4. Select Enabled/Disabled as desired and confirm.

About reading rooms
Reading rooms can only be selected when the DICOM display function is selected.
Therefore, please refer to "Display functions", page 26 to correctly set
the display
function.
The American Association of Physicists in Medicine (AAPM) composed a list of pre-defined reading rooms.
Each of these reading rooms are defined by following param
eters:
• 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 27 to enable ALC.
The available reading rooms for your Coronis 5MP are:
CR/DR/ MAMMO Corresponds to light conditions in diagnostic
reading rooms for computed radiology, digital
radiology or mammography. This setting has the
lowest maximum ambient light.
CT/MR/NM Corresponds to light conditions in diagnostic
reading rooms for computed tomography, magnetic
resonance or nuclear medicine scans.
Staff Office Corresponds to light conditions in office rooms.
Clinical Viewing Room Corresponds to light conditions in diagnostic
reading rooms for clinical viewing.
Emergency Room
Corresponds to light conditions in emergency
rooms.
