In addition to Gamma grayscale settings, a setting is now available that follows the DICOM Gray Scale
Standard Display Function (GSDF). If a site’s PACS workstations are calibrated to the GSDF, this
setting may help to make the image appearance more uniform between the ultrasound system and
PACS. By default, GSDF is disabled for 19” Monitors and enabled for widescreen monitors.
•
For all monitors, you may enable the GSDF-compliant mode in the Utility pages.
System
->
System Display
->
Display
-> Enable DICOM grayscale mode (GSDF).
•
With GSDF disabled, the Monitor still uses a gamma curve that may be selected on the Touch Panel
(for backwards compatibility with sites that are happy with their PACS or may have a mix of older
systems).
•
With GSDF enabled on Widescreen Monitors, the gamma button on the touch panel affects the
image, emulating the appearance of that gamma, but does not affect the monitor.
-
With GSDF enabled on 19 inch Monitors, the manual monitor settings must be at factory
defaults to ensure GSDF compliance.
•
19 inch Monitors will need to be set up manually after upgrading since the default screen layout
settings in R6 are adjusted to Wide screen monitors. This can be accomplished via Utilities pages.
Go to
Utilities
->
System
-> System Display
Set the drop-down menu in Use Wide Screen for… -> Single Image to Off.
Make sure the checkbox in Side Panel
Content
-> Measurement Summary is checked.
