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,
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
