Changing Display Functions

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).
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.
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
•
for this reading room. This value can be adjusted within
certain limits determined by the selected reading room.
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.
