About GammaCompMD QA Client

GammaCompMD QA is a Display Maintenance and Quality Assurance system specifically developed to maintain Diagnostic Imaging Displays in a Medical Environment and ensure compliance with Digital Imaging and Communications in Medicine Grayscale Standard Display Function (DICOM GSDF).

GammaCompMD QA Client is the part of this system which is installed and used on workstations with NEC diagnostic imaging displays and review display in PACS environments. GammaCompMD QA Client can be used stand-alone as well as in a networked Display Maintenance and Quality Assurance environment and allows a user to:

Check display status – current luminance, active backlight hours and remaining backlight lifetime, display temperature and other hardware status information

Check PACS display information - serial number and asset ID, DICOM conformance and historical status data of the connected displays

Perform conformance check and re-calibration to DICOM

Check luminance uniformity across the display surface

Match pairs of displays - Luminance and Color matching to other displays in the field

Copy display performance settings from one display to another

Automate maintenance - schedule calibrations and conformance tests

Generate reports of QC tests performed - following AAPM TG18, ACR AAPM SIIM,

and JESRA X-0093 guidelines as well as regional support for DIN V 6868-57, DIN 6868-157 and IEC 62563-1.

Different user levels

GammaCompMD QA Client features an intuitive user interface with three different customizable user levels. The Advanced user level contains access to the complete menu and configuration structure, and is aimed at expert users, PACS administrators and Service Providers. A second Technician user level has slightly restricted menu options, which are suited to medical physicists and radiographers who need to carry out conformance checks and QA tests. The final Radiologist user level is aimed at Radiologists with visual tests, to confirm the DICOM compliance of the display quickly.

Automated Procedures

GammaCompMD QA Client provides a high level of automated procedures. While the Auto Mode for a simplified calibration routine and Scheduled Tests ensure a more productive work process, automated data backup increases data safety and QA peace of mind.

GammaCompMD QA Client User Manual

Full network capability

With various supported network protocols, NEC displays can be easily integrated and configured into a PACS network infrastructure. The GammaCompMD QA network system performs network communication between GammaCompMD QA Server and associated GammaCompMD QA Client workstations. These workstations can be either diagnostic imaging workstations or client clinical referral workstations as part of a PACS system.

The GammaCompMD QA network system uses a low bandwidth TCP/ IP socket protocol for communication between Client workstations (maximum 1000) and the Server for display status information, remotely initiated calibrations and conformance tests and central retrieval of calibration and QA test results.

The control center of the GammaCompMD QA Server is HTTP web browser based and therefore the server can be managed from any workplace within the LAN environment on the same site. VPN concepts may be used to manage a network over several physical sites, as long as routing schemes as well as Network Security policies allow the communication.

The following drawing shows the structure of the GammaCompMD QA Client software, when installed on a workstation.

Figure 1: GammaCompMD QA Client software structure

GammaCompMD QA Client consists of several Graphical User Interface (GUI) Applications and several System Services running in the background, even when no user is logged in.

GammaCompMD QA Client User Manual

The Applications are called up from a taskbar icon, where a user - depending on user level - checks display status, does calibrations, conformance tests, QA tests or visual tests.

The three most important System Services are:

The QAEngine Service

Communicating with the connected displays and sensors, the Applications, the Database Service and - when connected - with the GammaCompMD QA Server.

The Database Service

Controlling a local database system to save all events and results and communicating with the Applications via the QAEngine Service.

The Scheduled Backup Service

Taking care of automated backups of the database contents, when enabled and maintained active schedules. During installation of GammaCompMD QA, a GCMDQABackupUser account is created to manage the background operation of this service.

The communication of these system services with the Applications and the GammaCompMD QA Server is managed using different IP addresses and different TCP Port addresses.

Therefore it is crucial for successful installation and operation of GammaCompMD QA Client that these addresses are not blocked, firewalled or run in conflict with other applications on the workstation. GammaCompMD QA Client is installed with the following IP addresses and TCP Port addresses (numbers) by default:

-System Service (including QAEngine service and Backup service):

-IP: Localhost, TCP Port: 53250

-Database Service:

IP: Localhost, TCP Port: 5432

If required, these TCP Port addresses may be modified later with the 7.7.1.2 Reinitialize System Configuration (page 108) menu.

NOTE: An additional Event Logger system service will be used to communicate with the

GammaCompMD QA Server, using the server’s target IP address and HTTPS protocol with default TCP Port address: 443. This service however is not enabled during Installation. See 7.7.1.2 Reinitialize System Configuration (page 108) to configure the server connection.

2.Checking System Dependencies

2.1. External Sensors

External sensor drivers are included with the GammaCompMD QA Client. Please install GammaCompMD QA Client before connecting any external sensor to the system. If multiple external sensors are connected simultaneously, they will not be correctly identified. Please connect only one external sensor.

2.2. Attaching MD-N2M5B Sensors and External Sensors

The NEC MD-N2M5B external sensor can be used to perform automated calibrations on some display models. Some MD-N2M5B sensors and external sensors cannot be stopped by the operating system (the [Safely Remove Hardware] icon is not shown in the taskbar). To remove a sensor that does not have this icon, only remove it after checking that the sensor is not in use. It is recommended that the sensor be removed after stopping the GammaCompMD QA Client.

2.3. Updating GammaCompMD QA Client with MD-N2M5B sensor(s)

If updating from GammaCompMD QA Client Version 4.0.10, the settings of MD-N2M5B sensor will be discarded. Set it up again after upgrading. For more information about sensor settings, refer to 7.2.6 Sensor Setup (page 77).

2.4. Using the CA-210 Color Analyzer

If connecting with serial communication, set the baud rate for the sensor unit to 9600bps. The sensor will not be detected if it is set at another baud rate. Settings are not necessary when connecting with USB communications. Also, special modes set at the CA-210 (MEAS or 0-CAL) will not be recognized by GammaCompMD QA Client. Please follow the instructions displayed at the start of calibration and startup to properly set the mode. You cannot use a CA-210 which supports two or more measuring probes. Only one probe connection is supported. Please refer to detailed instructions how to use this instrument in the CA-210 user manual.

2.5. Using the IBA LXplus instrument

For ambient light measurement, the optional lux sensor needs to be attached to the LXplus instrument. Please turn the LXplus power to OFF when attaching / detaching the Lux sensor.

If the buttons of the Sensor Contact Position Guide (Figure 57) or Continue Operation dialog (Figure 5) are not shown, push the ESC key to cancel the operation.

When displaying two or more inputs on one screen, it is necessary that both inputs are connected to the same display controller. Displays cannot be managed properly when each input is connected to a different display controller.

When displaying two or more inputs on one screen, please connect the signal cables of same connector type (Display Port/DVI/HDMI) to the display.

Any change of Windows display settings or display controller or input or connection of a different display typically requires an update of configuration settings. In such a case, please execute “Re-initialization of the Display Configuration” in GammaCompMD QA Client.

Executing QA Test with PIP MODE equipped displays will always show Continue Operation dialog (Figure 5) regardless of PIP MODE setting (ON/OFF). If the screen configuration is correct, press “Continue” to continue your operation.

If using this function on a display with PIP MODE (PbP), you need to input the appropriate resolution on the screen to perform correctly the visual test. When you change the resolution manually, please return to the original settings after the visual test.

When the display sensor (Front sensor model or Retractable sensor) is used, be sure to set the both the EXPANSION mode and the PIP MODE to “FULL” in the ON-SCREEN-DISPLAY (OSD) of the display.

Please set the PIP MODE not to "Picture in Picture" but to "Picture by Picture".

GammaCompMD QA Client User Manual

If the operation with the PIP MODE (PbP) goes wrong, connect the PC with the display using an USB cable. This is an alternative way of communication between PC and Display.

Refer to the display's documentation for details.

If the restoration of PIP MODE (PbP) from OFF to ON takes unusually long time, connect the PC with the display using an USB cable. Refer to the display's documentation for details.

After the calibration, the BLACK LEVEL value may return to the value before the calibration when PIP MODE (PbP) is set to OFF or ON. In this case, please set the value of BLACK LEVEL to 50.0% by the OSD menu.

In MD302C6, when two inputs of INPUT1+INPUT2 will be displayed, both inputs should use the same type of connector, and set up to the same resolution. Set up coordinates according to correct example.

If the calibration with the PIP MODE(PbP) goes wrong, execute 7.7.1.1 Re-initialization Display Configuration after setting PIP MODE to OFF. Execute calibration again after re-initialization.

When displaying two or more inputs on one screen, please unify Picture Mode setting, Luminance setting, Contrast setting, and Black level setting via the ON-SCREEN-DISPLAY (OSD) menu.

3.2. Installation of the internal database

During the installation process, GammaCompMD QA also installs a PostgreSQL database, as shown in Figure 10.

Figure 10: Database installation in progress…

This database is used to save all calibration actions, measurement data, QA tests and alerts and to build a history of the status of the connected display over time.

In addition, the database is used for providing actual and historical data, when the Client communicates with a GammaCompMD QA Server in a networked environment.

In case that a problem occurs during database installation or initialization, a message pops up with an error code. Below find a small list of error codes and a short description related to the installation/initialization of the GammaCompMD QA Client internal database during installation.

Error Code	Description

8	Database connection error

13	Cancelled by another process

26	Database initialization error

33	Exceptional error in database

GammaCompMD QA Client assumes that the user installing this application has full (local) administration rights.

The database communicates with the main application and with other system services via IP address (127.0.0.1; localhost) and TCP port number: 5432.

To find the cause of an installation failure, please check (among other possible causes):

Are there any limitations to the local administrator rights, or is an automatic creation of an account blocked, i.e. via Microsoft’s advanced group policy management?

Any TCP port conflicts with other applications, or any firewall port blocking?

Does the system run another PostgreSQL or other database installation?
