Concepts
•
The Display Function menu lets you select a display function (DF).
•
When you select the DICOM DF you can define the DICOM DF to be
recalculated taking the ambient light into account. This can be a
continuous recalculation (“Continuous DICOM ALC” on) or single
recalculation (“Continuous DICOM ALC” off).
recalculated taking the ambient light into account. This can be a
continuous recalculation (“Continuous DICOM ALC” on) or single
recalculation (“Continuous DICOM ALC” off).
•
When you choose for a single recalculation, the recalculation can
be based on an illuminance of 0 lux (“Dark Room”) a preset value
(“Preset”) or a single, real-time measurement (“Measured ALC”).
Both Preset and Measured ALC correction values are determined by
the selected reading room.

Both Preset and Measured ALC correction values are determined by
the selected reading room.
•
In the case of “Preset” or “Measured ALC” you must select a
reading room that corresponds to the type of room the display is
installed in. E.g. if the display is installed in a room where CT scans
are observed, the “CT/MR/NM” reading room is the preferred
selection.

•
The reading room is defined by 3 parameters:
•
Maximum Ambient Light defines the maximum light
allowed in this type of room. This value can be adjusted
within certain limits determined by the selected reading
room.

Preset Correction Value is the predefined correction value

•
Measured ALC Value is the averaged measured ambient
light for this reading room. It can be changed by executing
the “Measure ALC Value” function.

•
The reading room parameters are pre-defined in the display
according to the AAPM (American Association of Physicists in
Medicine). However they can be changed within certain limits.
