GammaCompMD QA Client User Manual
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.
Copyright © NEC Display Solutions Ltd., 2006 -2015 8
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.

IMPORTANT NOTES:
・ Unlike other sensors, retractable sensor executes calibration automatically when connected
to the system. As long as PIP MODE main screen setting is correctly done, calibration will be
completed properly without showing Sensor Contact Position Guide (Figure 57 ) or Continue
Operation dialog ( Figure 5). If the screen is not correctly set, calibration will stop with an
error message. Please set up PIP MODE correctly again and re-execute the calibration.
・ 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 “FUL L” in the ON-SCREEN-DISPLAY
(OSD) of the display.
・ Please set the PIP MODE not to "Picture in Picture" but to "Picture by Picture".

Database initialization error
Exceptional error in database
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.
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?
