Display Function
A Display Function describes how a display device converts the video
signals at the inputs into light.
In the context of a medical viewing station, a display device is the
combination of display controller (graphics board) and display.
The display function is a graph that shows how the light from the
display panel evolves from minimum to maximum luminance while the
data levels at the input of the display controller go from 0 to maximum.
DICOM
DICOM stands for Digital Imaging and Communications in Medicine. It is
a standard developed by the American College of Radiology (ACR) and
the National Electrical Manufacturers Association (NEMA).
The standard specifies how digital image data can be moved from
system to system.
In addition, Supplement 28 Part 14 specifies a function that relates pixel
values to displayed Luminance levels and is called Grayscale Standard
Display Function.
Presets and Internal memory system
The memory of the display contains minimum 70 fixed and 59
programmable Presets.
When you connect a video signal, the display checks in the memory for
a matching Preset.
If it finds one, it selects the corresponding settings and parameters from
the memory. If it does not find a matching Preset, the display uses
default settings to display the image.
When you make adjustments and save the changes, the current Preset
is saved as programmable Preset. If this happens while all
programmable Presets are occupied, the oldest programmable Preset is
overwritten automatically.
