What’s New in Version 6.x Series
Dome Display
Support has been added for the new Dome E2cHB display,
a 2-megapixel, color, high-bright unit.
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.
Page 6
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.
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
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 Dome CXtra services, including the Enterprise
Management Service, are now available in a single CD package.

Page 7
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 plugins, they each use the Reporting service for listing properties, logging
events, and saving history.
Display Compatibility
Dome CXtra services enhance the functionality of these
display systems:
• Dome CX
• Dome EX
• Dome QX
• GX2MP
• 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 53.
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
The RightLight service performs backlight stabilization, DICOM
calibration, and automatic and manual conformance testing for
Dome CX and Dome EX displays. 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 that RightLight performs
regularly, you can perform manual conformance testing as desired,
using an optional external photometer.
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.
RightLight Service | 13
Page 18
For Dome E2c, Dome E3c, Dome E3cHB, and Dome E4c 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.
Configuring the RightLight Service
If the Privilege service has been installed, you must log on as
a privileged user to change the RightLight configuration. (See
page 96.)
To configure the RightLight service
1 Open the Dome CXtra Services menu and select RightLight Panel
Configuration. The RightLight Panel Configuration dialog appears
with these tabs:
• Backlight
• Calibration
• Ambient
• Color
• Auto (Conformance) Alerts
• Manual (Conformance) Alerts
2 Check the selection box for each display you want to configure, or
click Select All.
3 Select a tab and change the settings as described in the following
sections. Click Apply to activate the changes without closing the
dialog; click OK to activate the changes and close the dialog.
Backlight tab
For displays selected, you can view the values of these parameters:
• Black level in cd/m2
• White level in cd/m2
• Backlight use in hours
• Brightness as a percentage of maximum effective brightness
14 | Dome CXtra
Page 19
In the White Level field, type the target white level value (in cd/m2) or
use the arrow keys to change the value shown. Click Apply or OK.
NOTE: White Level values are limited to the upper and lower ranges
specified per display.
RightLight stabilizes the backlights of the selected displays to attain
the target white level. The system may require a few moments for the
white level to stabilize after adjustment. This table shows the default
target white levels for each type of Dome CX and Dome EX display.

Page 20
Dome CXtra gives you three options for controlling dynamic range of
displays.
• Maximize - Causes each selected display to be calibrated using its
full dynamic range. The dynamic range of the selected displays
may differ.
• Equalize - Causes all selected displays to be calibrated using the
same dynamic range. The system locates the selected display that
has the smallest dynamic range and adjusts the dynamic range of
the other selected displays to match it.
• Specify - Causes all selected displays to be calibrated using the
specified dynamic range. The system notifies you if any of the
selected displays cannot achieve the specified dynamic range.
If all the selected displays have similar dynamic range, there may be
little or no visual difference among the selections.
The black levels and white levels shown on the Backlight tab include
the ambient light level specified on the Ambient tab.
NOTE: Choosing the Native or the No RightLight Calibration option on
the Calibration tab or on the services menu prevents RightLight from
equalizing black levels. When you do this, you are no longer applying
DICOM calibration.
16 | Dome CXtra
Page 21
Calibration tab
Select one of these response functions for auto-calibration:
• DICOM Response Function (default) – Calibrates to the DICOM
Grayscale Standard Display Function. See DICOM PS 3.14-2000
(Digital Imaging and Communications in Medicine (DICOM),
Part 14: Grayscale Standard Display Function).
• Exponential (log linear) Response Function – Calibrates to an
exponential (log linear) response function. The logarithm of the
luminance is a linear function of the digital driving level.
• Native Response Function – Automatically sets the flat panel to its
native response function (characteristic curve). The characteristic
curve is the response function of the panel with no calibration
applied. This is the display function created by loading a linear
gamma correction table, or GCT.
• No RightLight Calibration – Turns off auto-calibration. Choose this
response function if you are using an external calibration product
such as the Dome Calibration TQA™ system. Dome CXtra retains
GCTs currently set or created by an external calibration. RightLight
stabilizes the backlights only.
CAUTION: Do not calibrate with an external calibration product,
such as the Dome Calibration TQA system, unless your response
function is set to No RightLight Calibration. Otherwise, RightLight
overwrites the gamma correction table.
Check the selection box for each function you want to place on the
services menu, then change the operating parameter via the menu.
RightLight Service | 17
Page 22
Ambient tab
Specify the ambient light in the viewing area. Select the ambient light
description that best fits the display location:
• Low (reading room - 0.20 cd/m2)
• Moderate (typical office - 0.80 cd/m2)
• High (brightly lit office - 1.50 cd/m2)
• Custom – Fill in a value ranging from 0.00 (default) to 5.00 cd/m2.
The RightLight service allows you to enter luminance in cd/m2
resulting from the diffuse reflection of ambient illuminance.
Since typical Dome panels have a reflectance of 1.25%, given
illuminance E in lux, you can calculate the luminance in cd/m2
using this equation:
luminance = 1.25% × E / π
The default values are typical of reading rooms (approx. 50 lux),
moderately bright offices (approx. 200 lux), and brightly lit offices
(approx. 375 lux).
NOTE: Choosing the Native or the No RightLight Calibration option on
the Calibration tab or on the services menu prevents RightLight from
correcting for ambient light. When you do this, you are no longer
applying DICOM calibration.
18 | Dome CXtra
Page 23
Color tab
Specify the panel appearance of Dome E2c, Dome E2cHB, Dome E3c,
Dome E3cHB, and Dome E4c displays, with or without calibration.
Appearance. Use options in the Appearance field to specify blue,
clear, or default when you do not color-calibrate the display panel.
Calibrated color coordinates. Use options in the Calibrated Color
Coordinates field for precise specification of color coordinates. Apply
this method, for example, with multiple displays when a discrepancy
appears in color matching after you have selected an option in the
Appearance field.
First, click Color Calibrate to run the calibration wizard.
Next, test and accept the calibration.
Then, set the color temperature by Kelvin scale (from 5000 to 12000)
or specify the CIE xy coordinates.
Click Apply or OK.
NOTE: The LCD II photometer is required for color calibration of
the Dome E2c, Dome E2cHB, Dome E3c, Dome E3cHB, and
Dome E4c displays.
RightLight Service | 19
Page 24
Auto Alerts tab
Specify the conformance test(s) you want RightLight to run. Every
5 minutes, RightLight automatically performs the tests selected on
this tab. For each test you select, you can specify a threshold value
that defines a test failure. RightLight alerts you of a failure in these
three ways: by message, by entries in the History log, and by status
change of the Dome CXtra icon in the system tray. If the Enterprise
Management service is installed, an alert is also sent to the Dome
Dashboard or SNMP console application.
20 | Dome CXtra
Page 25
To set auto alert parameters
1 Select either the DICOM LUM test or the CX/EX White Level test or
select both.
For the DICOM LUM test, check the selection box. Then enter a
value for Maximum allowed. The DICOM LUM test is classified a
failure if it produces a value greater than the maximum allowed.
Enter a value ranging from 0 (zero) to 2 (default=1.00). A value of
0 (zero) indicates perfect conformance with the DICOM Grayscale
Standard Display Function. The DICOM LUM Test assesses the
standard deviation of JNDs (Just Noticeable Differences) per
digital interval.
EXAMPLE: Maximum allowed: 1.00 Result: A test result of 0.421
passes, because it is less than 1.00.
For the CX/EX White Level test, check the selection box. Then enter
a value for Tolerance ±. The CX/EX White Level test is classified a
failure if the measured white level is outside the range defined by
this percent, applied to the Target Luminance defined on the
Backlight tab. Enter a value ranging from 0 (zero) to 25 (default =
10.00). Tests producing a white level value outside of this
percentage range generate a warning message.
EXAMPLE: Target white level: 600 cd/m2
Tolerance: ±10% Result: Values outside the range from 540 to 660
(600 ± 60 cd/m2) indicate a test failure.
