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 Measired 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.
