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 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.
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.

GammaCompMD QA Client User Manual Examples for correct setup Screen order in Windows setting view and actual display screen should be the same.
GammaCompMD QA Client User Manual When you perform a calibration, luminance measurement or QA test, PIP MODE will be turned off automatically. You can test the correct input, using the following: 1. Manually turn “PIP MODE” OFF on the display via control button. 2. For case (a), (c), (e) and (f), you should only see the image of display area #1, otherwise changes in connection sequence are required. For case (b) and (d), change some settings to see the image of display area #2 image as well. 3.
GammaCompMD QA Client User Manual If the main screen setting is correctly done, Sensor Contact Position Guide (Figure 57) will be shown before calibration or taking other measurements starts. If QA Test starts, the following message (Figure 5) will be shown before calibration or taking other measurements starts. When the circle and the rectangle are displayed correctly related to the center of screen, the user is allowed to continue the operation.
GammaCompMD QA Client User Manual 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.
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.

When the checkbox is checked, the minimum black level can be set within a range from 0.00 to 4.99 cd/m2.
GammaCompMD QA Client User Manual NOTE: This function is useful to lift the black level and make the dark portions of a typical DICOM image more visible against reflections of the ambient light on the LCD panel of a display. Due to this reason, regional/national obligations as well as recommendations from clinical studies may require raising the black level of diagnostic imaging displays. Calculate from Contrast Ratio button Displays the Custom Black Luminance Level dialog box, as shown in Figure 48.
GammaCompMD QA Client User Manual Figure 50: Ambient light measurement successful NOTE: External sensors which can measure ambient light are i1 Display2, ColorMunki, i1 Pro, Spyder3, i1Display Pro, LXPlus, Luxi, MD-N2M5B, LXcan or LXchroma. Please make sure to connect the external sensor and test the connection. Please refer to 7.2.6 Sensor Setup (page 72) for correct sensor selection and connection test.
GammaCompMD QA Client User Manual Use/Don’t use Ambient Light Compensation Select between Don’t use Ambient Light Compensation or Use Ambient Light Compensation. Ambient Light Compensation is active during Calibrations, Conformance Tests, White/Black Luminance Measurements and Uniformity Tests. Illumination Shows the value of illumination (ambient light, unit: lux) as measured by the display’s ambient light sensor at time of installation.
GammaCompMD QA Client User Manual 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.
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.
GammaCompMD QA Client User Manual rights, an ICC profile will not be created. Also depending on the workstation environment, the ICC profile may not be recognized automatically by the Windows Color Management System (CMS). In this case, you need to set it up manually. NOTE: For most current applications in the medical environment, an ICC profile is not required, therefore this box may usually be unchecked.
GammaCompMD QA Client User Manual Source of primary color chromaticity values for ICC Profile Select from the following three options for the value to use when creating the ICC profile. ・ Automatic When creating the ICC profile, a suitable value is automatically selected between sensor measurement values and measured values from the factory. ・ Calibration sensor measurements Use the values of the sensor to create the ICC profile. ・ Factory data Use the values from the factory to create the ICC profile. 7.
GammaCompMD QA Client User Manual NOTE: For scheduled execution or test from the network, the display sensor is used regardless of the sensor selection. When a display sensor is used with a wide format display, be sure to set the EXPANSION mode to “FULL” in the OSD of the display. Figure 55: Preferred Sensor Selection Listbox Display Sensor Selection If a display with integrated front sensor is selected, the model name of the display is shown.
GammaCompMD QA Client User Manual Reference Calibration is used to re-adjust either the integrated front sensor of a display or a MD-N2M5B mounted on top of the display. To re-adjust a display sensor, both the display sensor and an external sensor need to be connected. Click the Reference Calibration button and perform the re-adjustment by following the displayed messages.
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.
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.
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.
