About display functions
Native, uncorrected panels will display all grayscale/color levels with luminance increments that are not
optimal for crucial diagnostic information. Studies have shown however, that in medical images certain
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.

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.
