Choosing Display Calibration
Besides DICOM calibration, you can choose to use exponential,
gamma, or original display calibration. Open the CXtra Services
menu, then select DICal Panel Configuration and Calibration tab.
Choose one of these response functions for auto-calibration:
• DICOM Response Function – Calibrates to the DICOM Grayscale
Standard Display Function. Refer to DICOM PS 3.14-2000 (Digital
Imaging and Communications in Medicine (DICOM), Part 14:
Grayscale Standard Display Function).
• Exponential Response Function – Calibrates to an exponential (log
linear) response function. The logarithm of the luminance is a linear
function of the digital driving level.
• Gamma Response Function – Calibrates to a gamma (nonlinear)
response function. The default value is 2.2. The range extends from
1.5 to 3.5; the CRT gamma standard ranges from 2.0 to 2.5.
• Original Response Function – Calibrates the desktop its original
response function. The characteristic curve is the response
function of the display with no calibration applied. This is the
response function created by loading a linear gamma correction
table, or GCT. (This function is appropriate for running typical
Windows applications.)
