What’s New in Version 6.x Series Dome Displays Dome CXtra support has been added for the Dome S6c display, a 6-megapixel color unit with DVI video connectivity, and the Dome GX24 display, a 2-megapixel unit with DisplayPort and DVI video 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. 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.
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.
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.
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.
CXtra Services The following services constitute the Dome CXtra software. RightLight™ – Assures backlight stabilization for your display panel, calibrates your panel to the DICOM Grayscale Standard Display Function, automatically tests the calibration for conformance, allows manual conformance testing, and supports DICOM calibration at various color coordinates on Dome color displays. (Manual external sensor conformance testing requires the LCD or the LCD II photometer.
Privilege – Password-protects operating parameters of the display system. Reporting – Collects, displays, and prints configuration data, characteristics, and event logs created by most other services. Enterprise Management – Manages displays from a central location. Requires SNMP console (not provided) for remote viewing. The use of CXtra services is display-dependent.
System Requirements The Dome CXtra software requires one of these operating systems: • Windows 7 (x86 or x64) • Windows Server 2008 R2 (x64 only) • Windows XP Professional (x86 or x64), Service Pack 3 Installing the Dome CXtra Software NOTE: Install the Dome CXtra software to a local disk drive only.

RightLight Service The RightLight service performs backlight stabilization, DICOM calibration, automatic conformance testing, and manual conformance testing via an external photometer for 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.
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.
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 138.) To configure the RightLight service 1 Open the CXtra Services menu and select RightLight Panel Configuration.
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 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.
NOTE: If you set the white level too close to the maximum brightness capability of the display, frequent warnings on high white levels may appear. To correct this problem, reduce the white level setting on the Backlight tab until the warnings stop appearing or use the CXtra Preference dialog to disable the warning popups. If you have a requirement to exceed the maximum limit, you can do so but you void your display warranty. Contact NDSsi Customer Care for instructions.
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.
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.
Color tab Specify the panel appearance of Dome Ex, Dome GX4MP, and Dome Sx color 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.
Front Sensor tab Specify the front sensor conformance test(s) you want RightLight to run. You can schedule testing to run automatically each day and conduct testing manually. 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 CXtra-enabled workstation is connected to Dome Dashboard, an alert is also sent to the Dashboard app or SNMP console.
• For the DICOM LUM test, enter a value for Maximum allowed. Then check the scheduled or manual selection box, or both, for test alerts. 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.
Rear Sensor 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.
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.
External Sensor tab Specify the external sensor tests that you want to complete manually. For each manual test that you select, you can specify a threshold value that defines a test failure. When a failure occurs, the CXtra icon is set to a warning state. In addition, if the CXtra-enabled workstation is connected to Dome Dashboard, an alert is also sent to the Dashboard app or SNMP console. Selections made on this tab determine operating parameters for the Conformance Wizard, which guides the manual test.
2 Select the number of luminance measurements you want to make during each manual test. Note: For the external sensor, the default number of measurements is 15. When you select All, 256 measurements are taken on 8-bit display systems; 1024 measurements are taken on 10-bit systems.
Checking Conformance via the Front Sensor Front sensor conformance tests are run per criteria you input for auto-scheduled or manual testing. If you have the Privilege service installed, you must log on as a privileged user before you run a front sensor conformance test. (See page 138.) To run the Front Sensor Conformance Test on demand, open the CXtra Services menu, select RightLight Conformance > Front Sensor Conformance Test. The test dialog appears onscreen while the conformance check is in progress.
Auto Conformance Testing via the Rear Sensor Automatic conformance testing shows how well your display conforms to the DICOM standard. RightLight automatically performs the tests selected on the Rear Sensor tab every 5 minutes. See page 25 to view or modify the test parameters. If you have the Privilege service installed, you must log on as a privileged user before you set up auto conformance testing. (See page 138.
To run an external sensor conformance test 1 Open the CXtra Services menu. Select RightLight Conformance > External Sensor Conformance Wizard. 2 Click Next to continue. 3 Click Initialize RightLight Panels. Upon completion of the process, click Next to proceed.
4 Put the photometer on the target and click Measure. If the White Level is unaligned with the target by 15 percent or more, a warning dialog appears. You can choose to perform White Level calibration to the target, ignore the warning and continue the measurement of conformance data, or direct the Conformance Wizard to skip the display panel, redo the initialization, or close.
5 Upon successful completion of the conformance measuring, as indicated by the Success icon, click Next. You have the option to view the report via this dialog. 6 Click Finish to close the wizard.
After you close the Conformance Wizard, RightLight enters the event in both the Reporting History log and the Conformance History log. All RightLight history events from conformance tests are recorded in the Reporting History log. RightLight provides additional information on conformance events in graphical and tabular formats in the Conformance History log.
Checking Current Conformance Status To view the results of the latest manual (external sensor or front sensor) conformance test, open the CXtra Services menu. Select RightLight Conformance > Current Conformance Status. In the same dialog, you can also view the results of the latest automatic (rear sensor) conformance test.
Reviewing Conformance Events Dome CXtra polls RightLight automatically for its status every 5 minutes, which causes the user-selected tests to run. The system makes an entry in the Reporting History log by the specified logging interval on the Auto Alerts tab and whenever it detects a status change. NOTE: When you make changes on the Rear Sensor tab, conformance tests run immediately. When you perform a manual conformance test, the system also makes an entry in the Reporting History log.
Reviewing Manual Conformance Data For manual conformance tests run via the front or external sensor, you can view data in graphical or tabular format by selecting sensor type, display model, and date. Not the following: • You must be using a Dome Sx display to view test results from both front and external sensors; select one or both check boxes on the dialog. With a Dome Ex display, all data result from conformance testing with the external (or manual) sensor.
Graph type • Response graph. Plots the measured luminance at various driving levels (P-values). Luminance is shown along the Y axis using a scale that you select from three options: Linear / Lum, Linear / Log Lum, and Linear / JND Lum. The graph consists of the luminance values specified by the DICOM standard and the luminance values measured during the conformance test. The better the data points align with the curve, the better the DICOM conformance.
• Conformance graph. Plots Just Noticeable Differences (JNDs) per luminance interval. The graph shows the mean value for JND/ luminance interval, the DICOM Luminance Uniformity Metric (LUM), and the line of best fit (FIT). These values are useful in quantifying the quality of conformance with the DICOM Grayscale Standard Display Function. The closer the JND values are to the mean line, the better the DICOM conformance.
Tables tab To view or print a conformance test, choose a table type, display, and selected test date and time to view or print the tabular data. When using multiple displays, choose the individual display for which you want test results from the Display pull-down list. Select a particular conformance test by date and time from the Date pull-down list. Table type • Response table. Lists the luminance value measured for each luminance interval in a selected conformance test. • Conformance table.
• Color table. Lists the following data values by Kelvin scale or CIE xy coordinates.

Advanced Options When you connect a third-party monitor or unsupported display to your system, you see that the Dome CXtra software labels it “unknown” and “not” characterized in the DICal Panel Configuration dialog. The DICal service needs to characterize or recognize a display before it performs calibration. When the third-party monitor or unsupported display lacks a characterization data file, run the characterization wizard, then save the panel type with a unique name.
Select the data file to export, then store it in the Dome CXtra dat folder on the other system. Enabling DICOM Calibration on Third-Party Monitors After characterization, operate the third-party monitor with Desktop DICOM Calibration enabled. You can undo the Panel Type selection for third-party monitors using Edit Type. Choose and click OK.
Test Patterns Service You can view a variety of test patterns for assessing image quality using the Test Patterns service. Two categories of test patterns are installed with the service: • AAPM (American Association of Physicists in Medicine) TG18 • Miscellaneous patterns such as SMPTE, horizontal and vertical ramps, and geometric distortions You can also import custom test patterns in .DCM, .DC3, .JPG, or .TIF formats, as well as perform visual and interactive evaluations.

To set up entries on the Displays tab Review the characteristics of each display panel connected to the computer. You can indicate how each panel is used by selecting a performance class as described below. 1 Click the Displays tab. 2 Select a display in the Display pull-down list. The system supplies values for the attributes shown, if known. 3 Designate the selected display as Primary or Secondary performance class by clicking the appropriate radio button.
To set up entries on the Reminders tab Schedule optional reminders for completing tests other than acceptance. For example, if you specify a reminder for the daily test suite, the system automatically generates a reminder message for each display that you have not tested. Dome CXtra provides reminders for only those tests that are enabled. The routine tests (daily, monthly, annual) are not enabled until an acceptance test has been completed for a given display and the report saved for a given display.
3 Select the type of reminder message you want to receive — Informational or Warning. Selecting the Informational reminder adds a reminder event to the History log for each display at the intervals specified. Selecting the Warning reminder causes a message box to appear on your screen. In addition, the reminder event changes the Dome CXtra icon in the system tray and adds an entry into the History log for each display. If the reminder is issued as a warning, a status change trap is sent to the SNMP console.
To run a test 1 Open the CXtra Services menu and select AAPM TG18 Test. 2 Select a display panel in the Select Display list. 3 Select a test in the Select Test list box. 4 Click Run Test to access the wizard, which prompts you to complete each evaluation in the test. Where necessary, you enter measurement or evaluation data as you complete each evaluation. NOTE: Some evaluations require you to complete multiple wizard dialogs.
Viewing AAPM TG18 Test Results You can view the test results for a TG18 Test immediately after completing all evaluations. The Test Info dialog appears upon completion of a test. Enter your name in the Tester’s Name field and your organization name in the Tester’s Company field. Then pick among these options for viewing or saving the report: • Click View Report for a summary of evaluations completed. • Click Save Report to store the information.
When you click Save Report, Dome CXtra records the test event in the History log. You can then use the Reporting service to view events in the History log. Select the TG18 Test event in the log and click View Detail to review saved test results.
