BOUT DISPLAY FUNCTIONS
Native, uncorrected panels will display all grayscale/color levels at an
equal luminance. 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
diagnostic 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
Haunsfield 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.
User This display function will be automatically
selected when display functions are
defined by MediCal QAWeb.
Gamma 1.8
Gamma 2.2 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.
