The performance of 14 primary clinical display monitor workstations in use in the Radiology Department of a large acute NHS Trust was assessed using the methods and guidelines described by the American Association of Physicists in Medicine Task Group 18. Tests undertaken included the measurement of ambient light, display uniformity, luminance ratio, luminance response, maximum luminance and spatial resolution. Four display monitors failed to meet at least one of the test's guideline tolerances. In addition a number of display monitors were found to be operating at settings that might reduce their useful life span. These devices were either replaced or recalibrated by the installers, or were subject to local adjustment to ensure applicable standards were met. Consequently the study suggests that quality assurance testing of display monitors used for image reporting is necessary and valuable to ensure that images are viewed at an appropriate standard.
使用美国医学物理学家协会第18任务组描述的方法和指南,对一家大型急性国民保健服务信托基金放射科使用的14个主要临床显示监视器工作站的性能进行了评估。进行的测试包括环境光测量、显示均匀性、亮度比、亮度响应、最大亮度和空间分辨率。四个显示监视器至少未达到测试指南公差中的一项。此外,还发现一些显示监视器的设置可能会缩短其使用寿命。这些设备要么由安装人员更换或重新校准,要么进行局部调整以确保符合适用标准。因此,该研究表明,对用于图像报告的显示监视器进行质量保证测试对于确保以适当标准查看图像是必要且有价值的。
