About reading rooms
Reading rooms can only be selected when the DICOM display function is selected.
Therefore, please refer to "Display functions", page 22 to correctly set the display
function.
The American Association of Physicists in Medicine (AAPM) composed a list of pre-defined reading rooms.
Each of these reading rooms are defined by following parameters:
• the maximum light allowed in this type of room
The available reading rooms for your NIO 2MP LED Display are:

If you select Native, the native panel behavior will
not be corrected.
These are gamma functions that are shifted to take
into account the non-zero luminance of an LCD
panel when driven with a "black" signal. They are
especially useful in CT applications to improve the
perception of low Hounsfield values.
DICOM (Digital Imaging and Communications
in Medicine) is an international standard that
was developed to improve the quality and
communication of digital images in radiology.
In short, the DICOM display function results in
more visible grayscales in the images. Barco
recommends selecting the DICOM display function
for most medical viewing applications.
This display function will be automatically selected
when display functions are defined by MediCal
QAWeb.
Select one of these display functions in case the
display is to replace a CRT display with a gamma
of 1.8 or 2.2 respectively.
