Updated version of European breast tomosynthesis QC protocol (version 1.01)ĭue to the rapid developments the European breast tomosynthesis protocol (version 1.01) has been updated and released. Some text has been added regarding the mode in which mages have to be made in some methods of measurement.ĭownload the updated version here (bottom of the page).This has been done because feedback was received and was noted that the value of 1.0 mGy was difficult to achieve with sufficient image quality for DBT systems. The limiting dose value for 20 mm PMMA thickness has changed from 1.0 mGy to 1.2 mGy.The dose reference values have been changed to limiting values.Updated version of European breast tomosynthesis QC protocol (version 1.03) More information can be found here:įollowing the internet link below you will find the MoniQa test patterns: Since new review workstations are all LCD technology rather than CRT-based, the "Cx" patterns used to assess CRT monitor sharpness have been removed. The TG18-QC test patterns have been modified to match the matrix size and DICOM header formats of different vendor's digital mammography machines (to the best of our ability). The label (in the test pattern) has been changed from 'version 8.0' to 'modified version',

file format has been changed to mammographic DICOM image, Your system treats mammography images differently than images from other modalities Your system accepts only mammography images These modified AAPM TG18 images can be usefull when: However, if modified images are required to be able to test your system, you should keep in mind that this may mean your system does not comply with the DICOM standard! Modified Images (version 4) Therefore, two special versions of these images can be downloaded below. Some display systems can not be tested properly using these original images while some systems are not fully DICOM compatible, or because they treat mammograms differently from images from other modalities. The AAPM Task Group 18 test patterns described in the European protocol can be obtained from the Task Group 18 website ().

Start EIZO Monitor Testġ Pixel warranty varies by manufacturer. You should also clean the display prior to testing, since reflected light could cause dust particles to look like defective pixels. In order to ensure meaningful test results, your monitor should already be warmed up prior to testing (ideally for 30 minutes). This allows you to precisely assess even dark image areas. It is recommended that you carry out the monitor test in a dark room. For this reason, please note the manufacturer specifications (especially for the defective pixel test). You should therefore always assess your monitor within the context of its respective device category. For example, gaming monitors are distinguished by particularly short response times, whereas graphic monitors impress with a particularly homogenous image display and smooth gradients. The EIZO monitor test consists of various test scenarios that your monitor can handle to a greater or lesser extent, depending on the model.

You can check your monitor for defective pixels and get a sense of its viewing angle stability. You can carry out 13 individual tests to check how uniform the image display is across the entire monitor, for example, or if the text is displayed sharply. The EIZO monitor test lets you quickly and easily assess your monitor’s image quality.
