Dome CXtra QUICK REFERENCE
Dome® CXtra™ is a software solution that adds functionality to Dome medical imaging displays by using a common framework for consistent image quality and constant display maintenance. The Dome CXtra software provides these services: • RightLight – Calibrates diagnostic displays automatically to conform with the DICOM curve; offers manual conformance testing and options for viewing conformance data.
Dome CXtra Services Check the following table for the services designed for your display system. Refer to Dome CXtra User’s Guide for more information on the individual services.
Installing Dome CXtra When upgrading the software, all currently installed CXtra services are auto-selected for updating. If you deselect a service during the upgrade, the installed service is removed. WARNING: When the Dome CXtra application is running, power off the system before you either connect a DVI cable to or disconnect a cable from the Dome display. Connecting or disconnecting a DVI cable with the system power on may corrupt the display EDID data.
To install Dome CXtra NOTE: Install the Dome CXtra software on local disk drives only. Installation on network drives may cause some components to operate improperly. 1 Turn on your computer and log on with administrator privileges. 2 Insert the installation CD and run setup.exe. 3 Follow the wizard instructions to complete the installation. The application starts when the installation is finished. FOR FIRST-TIME INSTALLATION: By default, all services are selected for installation.
To uninstall the Dome CXtra software 1 Turn on your computer and log on with administrator privileges. 2 Select Windows Start > Settings > Control Panel > Add/Remove Programs (Uninstall on Windows 7). 3 Select CXtra to uninstall the entire application. 4 Click Change/Remove to start the uninstall process. Restart the computer. To use CXtra services 1 Click the Dome CXtra icon on the taskbar. 2 Select an option from the popup menu.
RightLight Service The RightLight service provides backlight stabilization, DICOM calibration, and auto and manual conformance testing, and also reports current white and black levels.
Configuring the RightLight Service If you have the Privilege service installed, you must log on as a privileged user to change the RightLight configuration. On the CXtra Services menu, select RightLight Panel Configuration to open the RightLight Panel Configuration dialog. Check the selection box for each display you want to configure, or click Select All. Select the following tabs in the dialog and change the settings as required.
Auto Conformance Testing Specify the conformance test(s) you want RightLight to run. Every 5 minutes, RightLight automatically performs the tests selected on the Rear Sensor tab. For each test you select, you can specify a threshold value that defines a test failure. RightLight alerts you of a failure in three ways: by message, by entries in the History log, and by status change of the Dome CXtra icon in the system tray. In addition, an alert is sent to the Dome Dashboard console or to an SNMP console.
Current Conformance Status and Conformance History Using the Current Conformance Status option, you can view auto conformance results and compare the current status with the last manual conformance results. You can review summary text reports of auto conformance events and manual conformance events via the Reporting History log. With the Conformance History option, you can retrieve details of manual conformance events in graphical and tabular formats.
White Level Calibration Service IMPORTANT: Only an administrator can calibrate the white level via the White Level Calibration service and restore factory calibration. The white level of a Dome display is stabilized by the internal RightLight photometer that is calibrated during display manufacture. The White Level Calibration service allows the administrator to calibrate the sensor using an external photometer. When the calibration is completed, the new calibration data file is stored in the display.
DICal Service You can calibrate GX24, GX2MP Plus, GX2MP, and select desktop displays to conform with the DICOM curve or with another calibration response function. With the optional LCD photometer, you can also perform custom calibrations and conformance tests. Configuring the service for display calibration First, check the brightness and contrast of your display. You must use the brightness and contrast settings for your particular display.
Calibrating the display The default DICOM calibration is applied to the display whenever you select DICOM Calibration on the main menu. Use an optional photometer to perform a custom DICOM calibration. Custom calibration uses the actual luminance values of your display to adjust the response curve. The new values are used to set the default DICOM calibration whenever you select DICOM Calibration.
Backlight Saver Service Specify when the display system turns off the panel backlights, to extend the display’s clinical life. The Backlight Saver service allows you to input a value, in minutes, for the Sleep After parameter. The system turns off the backlight when a period of inactivity exceeds this value. You can specify different parameter values for each day of the week and various periods during each day.
MQSA Quality Control Test Regular inspection and testing of diagnostic imaging displays designated for primary image diagnosis in mammography ensure display calibration and quality control. Only the Dome E5 and Dome S10 displays can be used for image diagnosis as regulated by the Mammography Quality Standards Act, or MQSA. The Dome CXtra software helps you set up test reminders for quality control activity and provides a way for you to record the results of the quality control tests electronically.
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 The following six sets of AAPM TG18 patterns are provided. Most of the patterns are available in a 1024 x 1024 size; some are available in a 2048 x 2048 size. Refer to Dome CXtra User’s Guide for more information.
Displaying Test Patterns NOTE: Some AAPM TG18 patterns have variations such as 10%, 50%, and 80%. To select and display a test pattern 1 Open CXtra Services menu > Test Patterns > View Test Patterns. 2 Click the plus sign (+) next to a test pattern set to see the variations. Then click a pattern or variation name to display that pattern. (Click Invert to change black to white and white to black. Not all patterns can be inverted.) 3 Click Hide Dialog to provide a clear view of the pattern.
Using Custom Test Patterns You can add, modify, and delete custom test patterns. To start, open CXtra Services menu > Test Patterns > Manage Custom Test Patterns. On the Add, Modify, or Delete a Custom Test Pattern dialog, you can set viewing parameters for each pattern and add custom test patterns in these formats: • DCM or DC3 (DICOM) • JPG • TIF or TIFF NOTE: You may need to log on as a privileged user to use custom test patterns.
When launched, the tests run sequentially on all supported displays. Upon completion, results are logged into Reporting History. To start, open the CXtra Services menu > Test Patterns > Evaluations. Use Setup on the Test Patterns Evaluation dialog to configure test parameters. Setup Use the three category tabs on the Setup dialog to configure parameters for scheduling, pattern selection, and user preferences. • Schedule.
