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 diagnostic information by correcting the native panel behavior.
The available display functions for your display are:
- Native: The native display panel behavior will not be corrected.
- Dynamic Gamma 1.8 or 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.
- sRGB: The sRGB color space combines a display function, color space and white point selection, and is designed to match typical home and office viewing conditions. It is widely used in most computer applications. Note: This setting does not fully set your display to the sRGB color space. Refer to “sRGB” to do this.
- User: This display function will be automatically selected when display functions are defined by QAWeb.
- Gamma 1.8 or 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.
- Test: For Barco service purposes only.
