What’s New in Version 6.x Series
Menu Update
Reporting Control has been changed to CXtra Preference. This
command change appears on the Cxtra Services menu and on the
related dialog. Use this dialog to disable the beeping sound that
occurs with some software functionality.
Front Sensor Scheduling
The functionality for specifically scheduled front sensor testing has
been eliminated. You can elect to run front sensor testing
automatically and manually. Automatic testing occurs each day.
Dome Displays
Dome CXtra support has been added for the Dome GX4MP display,
a 4-megapixel color unit with DVI video connectivity.
Support was added in previous versions of Dome CXtra for the
GX2MP Plus display, a 2-megapixel color unit with DVI connectivity;
Dome E3cHB and Dome S3c displays, both 3-megapixel color units,
and Dome S3, a 3-megapixel grayscale unit, all with DVI and
DisplayPort video connectivity; and the Dome S10 display,
a 10-megapixel grayscale unit with video input via DVI connectivity.
MQSA Test Service
You can set up test reminders for consistent quality control activity
and record the results of the quality control tests electronically.
NOTE: Applies to Dome E5 and Dome S10 displays only.

2 | Dome CXtra
Expansion of Manual Conformance Testing
With the addition of the front sensor on some models of Dome
displays, the Manual Conformance functionality has been bifurcated
into the External Sensor Conformance testing (using the photometer
device) and the Front Sensor Conformance testing.
External Sensor Conformance replaces Manual Conformance on the
CXtra Services menu and the Conformance wizard. All operational
procedures are unchanged.
Front Sensor Conformance has been added to the menu. With this
functionality you can perform auto and manual conformance testing.
NOTE: Applies to Dome S3, Dome S3c, and Dome S10 displays only.
White Level Maximum Limit Exceedance
If you have a requirement to exceed the maximum limit of the preset
White Level target range, you can now do so but your display
warranty becomes void. Contact NDSsi Customer Care for more
information.
European Reference Guidelines
The EUREF guidelines, organized by the European Reference
Organization for Quality Assured Breast Screening and Diagnostic
Services, promotes mammography care of high quality in European
Union member states. Users of Dome displays qualified for AAPM
TG18 can perform the White Level Calibration procedure to meet this
standard. See “White Level Calibration Service” on page 44.
Modification of Color Calibration Setting
Only an administrator, not privileged users, can modify the color
calibration setting accessible on the RightLight Panel Configuration
dialog, Color tab. (See page 22.)
NOTE: Applies only to Dome displays using the RightLight
functionality.

What’s New in Version 6.x Series | 3
Windows Platform Support
Support is available for the Microsoft Windows 7 (x86 or x64) and
Windows Server 2008 R2 (x64 only) operating systems.
Support for the Microsoft Windows XP x64 operating system was
added to the Dome®CXtra™6.x series in an earlier version.
CXtra Utilities
Users can start, restart, and stop all CXtra services and application,
and run CXtradiag with utilities. Access the tools via the Windows
Start menu.
NOTE: Windows administrator privilege is required to run the utilities.
Users without privilege must enter an authorized username and
password as prompted.
Fast User Switching
The Fast User Switching feature is not supported on display systems
using NVIDIA drivers previous to version 197.03.
Installation Upgrades
The installation procedure for Dome CXtra is now simpler, faster, and
more reliable. All services and features are installed by default. To
customize your installation, you must deselect the service or
application feature you do not wish to install.
White Level Calibration
Correction of the display white level can now be done via manual
conformance testing or with the White Level Calibration service.
A one-time, end-user calibration of the white level may be necessary
when the target luminance is outside the tolerance established for
proper display conformance, such as when the white level of a display
has failed a manual conformance test, or when two or more displays
in a multi-unit configuration show disparate white levels. An external
photometer is required.

4 | Dome CXtra
NOTE: Privileged users and administrators can calibrate the
white level if a display fails the White Level test during the manual
conformance testing. Only administrators can calibrate the white
level via the White Level Calibration service.
Support for 10-Bit Displays
You can now run the Dome CXtra software on Dome 10-bit grayscale
displays. You can check for 10-bit capability (both current and
maximum supported) on the Properties tab of the Reporting dialog.
You can also view 10-bit patterns (horizontal ramp and vertical
ramp test patterns) using the Test Patterns service. And in manual
external sensor conformance testing, you can take all 1024
measurements for more precise testing results.
Using Dome CXtra with Dome Dashboard
For best practice of using Dome Cxtra 6.x with Dome Dashboard 2.x,
observe the following requirement and recommendation.
• When using Dome Dashboard 2.x, make sure that Dome CXtra 6.x
or later is installed on each CXtra workstation.
• On the CXtra workstation, limit the retention of history to 365 days
(one year).
Single Dome CXtra Package
The separate packaging of the Enterprise Management Service has
been discarded. All CXtra services, including the Enterprise
Management Service, are now available in a single CD package.
Dome CXtra Limitation
When using a display configuration with the NVIDIA 1800 board in
Windows XP Span mode, the only video connection supported is
two (2) DisplayPort-to-DVI adapters.

Getting Started
The Dome CXtra software adds essential functionality to Dome
medical imaging display systems in diagnostic and referral settings.
By using the Dome CXtra suite of value-added services, you can
calibrate and maintain displays, run acceptance tests, and monitor
displays remotely. While the services operate as independent plug-
ins, they each use the Reporting service for listing properties, logging
events, and saving history.
Display Compatibility
CXtra services enhance the functionality of these display systems:
•DomeCx
•DomeEx
•DomeGx
•DomeSx
• Select Desktops
You can also install the Dome CXtra software on systems using
third-party commodity monitors to enable DICOM calibration. See
“Enabling DICOM Calibration on Third-Party Monitors” on page 95.
NOTE: When you add or remove displays on the Windows desktop,
you must restart the Dome CXtra software by rebooting the system.
(Refer to ReadMe file for more information.)
WARNING: When the Dome CXtra application is running on the
system, power off the workstation before you either connect a DVI
cable to or disconnect a cable from the Dome display. Connecting or
disconnecting a DVI cable with the workstation power on may
corrupt the display EDID data.

RightLight Service | 15
RightLight Service
The RightLight service performs backlight stabilization,
DICOM calibration, automatic conformance testing, and manual
conformance testing via an external photometer for Dome Cx,
Dome Ex, Dome GX4MP, and Dome Sx displays. Manual conformance
testing via the display front sensor is available for Dome Sx units.
With RightLight, you can set a target white level, equalize the black
level across the displays, set a desired response function, and specify
ambient light in the viewing area. This service also reports current
white and black levels.
RightLight automatically calibrates the displays at regular intervals.
Calibration adjusts the response of a display to conform to the
response function you specify. There are four calibration response
functions, one of which is a correction to the DICOM Grayscale
Standard Display Function.
DICOM calibration is based on the unique characteristic curve stored
in each display at the time of manufacturing. RightLight routinely
checks how well each display conforms to the DICOM standard and
calculates a Luminance Uniformity Metric (LUM) value that indicates
the degree of conformance.
Besides the automatic conformance testing and adjustment that
RightLight performs regularly, you can perform manual external
sensor conformance testing, using an optional photometer. On
Dome Sx displays, you can also perform manual conformance testing
with the embedded front sensor photometer.

16 | Dome CXtra
You can also calibrate the internal RightLight photometer to generate
a new calibration data file whenever the white level is outside the
tolerances set for the display configuration. Calibrating the white
level requires an external photometer.
For Dome Ex, Dome GX4MP, and Dome Sx color displays, you can set
color coordinates for panel appearance in one of two ways:
• Select an option for panel appearance with blue, clear, or default.
• Use the LCD II photometer to perform color calibration
when you specify color coordinates by color temperature
(Kelvin scale) or by CIE xy coordinates.
NOTE: Setting nondefault color coordinates can change the target
luminance range.
