grayscale/color parts contain more diagnostic information then others. To respond to these conclusions,
display functions have been defined. These functions emphasize on these parts containing crucial diag-
nostic information by correcting the native panel behavior.
Native
If you select Native, the native panel behavior will
not be corrected.
Dynamic Gamma 1.8
Dynamic Gamma 2.2
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 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.

About reading rooms
Reading rooms can only be selected whe n the DICOM displ ay 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:
Dark Room
Corresponds to light conditions of ideal dark
room. This setting disables the ambient light
compensation.
CR/DR/ MAMMO Corresponds to light conditions in diagnostic
reading rooms for computed radiology, digital
radiology or mammogra
phy. This setting has the
lowest maximum ambient light.
