Overview #
Calibration settings can be changed under the Settings > Measurement Settings tab:
Here you can adjust various factors that influence calibrations such as:
- Sample count (for greater accuracy)
- CIE D65 colour calibration
- Minimum and maximum luminance targets
Sample count #
The number of calibration samples impacts the time taken to complete calibration as well as the accuracy of the final calibration applied. Using a larger number of samples for Calibration Points may help to reduce GSDF. For most purposes, using 52 or 64 samples is optimal.
The sample count for the check phase of the calibration should be set to 18 to for valid GSDF values.
CIE D65 Colour Calibration #
To enable CIE D65 color calibration for your monitor, toggle the CIE D65 colour calibration option. This will be applied on the next calibration that is run.
Enabling this option may reduce the maximum luminance for your display to below what it is capable of, as some tradeoffs have to be made to correct for colour. If your display no longer meets the luminance requirement for your selected standard after applying colour calibration, it is recommended you disable this option.
Luminance Targets #
All radiology display standards have requirements for minimum and maximum luminance. By default, ViewIQ will target a minimum luminance of 1 cd/m2 and use the maximum luminance your display is capable of. This should allow for most standards to be met without having to make any changes (assuming that your display hardware is capable of meeting the standard).
However, you might want to adjust these targets to preserve your display (by reducing maximum luminance to that of the standard being used) or when using a custom standard. To set the minimum and maximum luminance enter your values into their respective fields and run a calibration:
