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.

therefore may not identify the displays correctly anymore. The following actions may solve

the issue:

- Rebooting the system will read in the latest display configuration, which is then used

by GammaCompMD QA.

- If this does not help, re-install GammaCompMD QA.

GammaCompMD QA Client User Manual

Level

Description

Advanced Mode

(Expert level)

Assumes a user who is typically a PACS system administrator or

third party Service Provider. All features of Display Maintenance

are available. Since the user at this level can set password and/or

access rights for the Technician Mode level, this level may also be

able to execute all Display Maintenance functions.

The Advanced Mode user should have local system administrator

rights, to be able to restart system services and set backup

schedules.

Technician Mode

(Standard level)

Assumes a user who is typically a Medical Physicist or Biomedical

Engineer who does not make any adjustments to the displays.

Depending on the password setting, only Quality Assurance may be

executed. The available features are limited to the items as

specified with 7.7.2.1 Access Rights Setup for Quality Assurance

(page 127). (Note: The Access Rights Setup for Quality Assurance

can only be modified by an Advanced Mode user.)

Radiologist Mode

(Visual test level)

Assumes a user who performs visual tests. Typically this is a

Radiologist or a Radiographer. Depending on the password setting,

only viewing of test patterns may be executed.

5.2. User Password Setup

As shown in User levels, GammaCompMD QA Client provides the following three user levels:

 Advanced Mode Display Maintenance (Expert level)  Technician Mode Quality Assurance (Standard level)  Radiologist Mode Show Test Patterns (Visual test level)

The functionality is different for each level. By default, all users can execute operations at all

levels from Advanced to Radiologist without a password, as no passwords are initially set.

To place restrictions on features that can be used in Technician and Radiologist level, an

Advanced Mode user must set passwords within 5.2 User Password Setup (page 45).

For the Advanced Mode (Expert level), it is recommended to set up a password to operate

GammaCompMD QA Client in a secure way. For further information about setting passwords,

refer to 7.7.2.2 User Password Setup (page 131).

into the display. No modification will happen if the check box

remains unchecked. The Illumination value is not updated.

Retrieve both factory preset values from the display

The initial factory shipment value of the Diffuse Reflection

coefficient is transferred from the display. The reflected luminance

value is then calculated using the Illuminance value measured by

the ambient light sensor of the display. The formula is:

Reflected luminance = Illuminance x Diffuse Reflection coefficient

Example: 0.04 cd/m2 = 20 lux x 0.002 cd/m2 per lux.

When using MD215MG, MD211G5, MD212G3 or MD302C6, this

function is disabled.

Measure and calculate

The illumination is measured automatically and the reflected

luminance value will be calculated.

When using MD215MG, MD211G5, MD212G3 or MD302C6, this

GammaCompMD QA Client User Manual

function is enabled.

IMPORTANT NOTES:

・ It is very important to keep the ambient light conditions during this adjustment

process and during any calibration process on the same level.

・ Be very careful and do not change ambient light conditions drastically around the

display during a calibration process. Otherwise an incorrect diffuse reflection

coefficient will be stored in the display and the Ambient Light Compensation

function will not work correctly.

・ The Diffuse Reflection coefficient typically ranges from 0.002 to 0.006 cd/m2 per lux

and highly depends on the type of anti-reflection treatment applied on the screen

surface. Changes may happen over time due to aging and/or poor surface treatment.

・ For a newly installed display you may use the function Retrieve both factory preset

values from the display to adjust the Ambient Light Compensation in the display

correctly. If this action reports unreasonably high Reflected Luminance values, use the

“Manually adjust the Reflected Luminance value” function in addition.

・ Please use the function “Manually adjust the Reflected Luminance value” with

utmost care. For a realistic Reflected luminance value in the actual installation

environment, a calibratable luminance meter (“telescopic type” or “distance

GammaCompMD QA Client User Manual

measuring”) is required to measure the reflected luminance of the screen surface of a

display – with the display’s power switched OFF and a clean surface.

・ The last Diffuse Reflection coefficient value uploaded to the display is used to

compensate ambient light changes by correcting the DICOM curve in the display.

・ When using MD215MG, MD211G5, MD212G3 or MD302C6, run the calibration after

setting Ambient Light Compensation. Ambient Light Compensation isn't reflected

until calibration is completed.

 ICC profile tab

models is selected. Therefore, please ignore the message “Reference Calibration is

highly recommended” for these models.

Instead, please select External Sensor as the Preferred Sensor. The integrated front

sensor of these models is re-adjusted automatically during a calibration using an

External Sensor.

・ Luminance Offset: An integrated front sensor or MD-N2M5B sensor can only

measure luminance in the periphery of the display screen surface. However, due to

the characteristics of an LCD display, there are differences in luminance and color

between the central region and the periphery of the display screen surface. When a

front sensor or MD-N2M5B sensor is being used, it is necessary to re-adjust such

differences (offset) in comparison with an external sensor. In case of integrated front

sensors, this offset is stored in the display itself. In case of the MD-N2M5B sensor, the

offset is stored in GammaCompMD QA Client.

・ Special care using MD-N25B: After the OK button is clicked in the Reinitialize Display

Configuration dialog box, as shown in Figure 89, specify the serial number again. If

this causes the combination of the display and the MD-N2M5B sensor to change then

it is necessary to repeat the reference calibration.

・ Reference calibration cannot be done with an external sensor without color support.

Please also refer to Additional considerations - Using sensor models without color

measurement capability below for details.

GammaCompMD QA Client User Manual

External Sensor Selection

The external sensor can be selected from the External Sensor

Selection listbox, as shown in Figure 56.

NOTE: Only one external sensor is supported at time and it will be the last selected sensor

model.

Figure 56: External Sensor Selection Listbox

Auto-Detect button Clicking on this button allows the external sensor to be

automatically detected, even if a sensor was not yet selected from

the External Sensor Selection listbox described above.

OK button Saves the sensor setting to the selected display and closes the

dialog box. The OK button cannot be clicked unless the Operator

Name is entered.

Cancel button Closes the dialog box without applying any changes. However, any

settings that were applied by clicking the Apply button cannot be

returned to its previous state.

Apply button Applies the settings but does not close the dialog box. The Apply

button cannot be clicked unless the Operator Name is entered.

Additional considerations

Using external sensors If a calibration or test is executed, the sensor contact position

guide, as shown in Figure 57, is displayed. Position the sensor on

the display according to the guidance and click the Continue

button at the bottom left of the screen to start the measurement.

GammaCompMD QA Client User Manual

A LCD display is fragile and may be damaged if the external sensor

is forcefully pressed against it. Never attach a sensor with suction

cups to the display. Always use the supplied cable and suspend the

sensor with a weight so that the sensor is stationary in front of the

display.

If the external sensor is separated from the screen during

calibrations or tests (i.e. by falling off), the process may fail. Be

sure to keep the external sensor in place, until the process is

completed. If the sensor has been displaced, position the sensor

on the screen again and best restart the process.

Figure 57: Sensor Contact Position Guide

Black Level setup Several supported external sensor models require the adjustment

of the Black Level (Dark Current) for improved accuracy. This Black

Level measurement will be performed before any calibrations and

tests. Please follow the guidance on the screen. In most cases, the

sensor needs to be placed on a dark surface for this setup.

Figure 58: X-Rite Chroma 5 during black level adjustment (Example)

GammaCompMD QA Client User Manual

Sensor selection rules External sensors cannot be used for all calibration operations. For

scheduled display calibrations or remote calibrations and DICOM

conformance tests, only a display sensor is appropriate.

On the other hand, some external sensor models are unable to be

used for Display Quality Assurance (QA), depending on regional /

national regulations.

NOTE: If an external sensor was selected for a display with Display Sensor, but this external

sensor is not connected during a measurement or calibration activity, GammaCompMD QA

will automatically change to the display sensor, without notification. Only the respective

reports will reveal this change.

Using sensor models without color measurement capability

Typical instruments used for Quality Assurance, i.e. LXplus, LXcan

or Luxi/Solo Light do not support color measurements. White

luminance calibration modes, other than Native and No Change,

as well as a Reference Calibration of a color display front sensor

are not supported. Please refer to 7.2.5 Calibration Setup (page

64) regarding the White Luminance Calibration mode and

Reference Calibration button in this chapter regarding reference

calibration.
