Abstract

In a filmless environment it is necessary to execute acceptance and constancy tests on monitors used for interpretation of medical images. Performances of Barco CRT MGD521 MKII, Barco LCD L685EX monitors have been evaluated. Acceptancepress were executed following AAPM Task Group 18 guidelines. Visual and instrumental evaluations of geometric distortions, reflections, luminances response, contrast, uniformity, resolution, angular response and veiling glare were made. Barco monitors showed optimal performances, while EIZO monitors were accepted with some reserve on their quality level. Finally a comparative evaluation between monitors and film (the actual gold standard) was performed by an interview of ten radiologists: the monitors showed a quality at least equal to film. These monitors are currently in use for routine medical interpretation.

摘要

在无胶片环境中，有必要对用于医学图像解释的监视器进行验收和稳定性测试。评估了 Barco CRT MGD521 MKII、Barco LCD L685EX 监视器的性能。根据 AAPM 任务组 18 指南进行了验收测试。对几何变形、反射、亮度响应、对比度、均匀性、分辨率、角度响应和光幕眩光进行了视觉和仪器评估。Barco 监视器表现出最佳性能，而 EIZO 监视器的质量水平则存在一些保留意见。最后，通过十位放射科医生的访谈对监视器和胶片（实际的金标准）进行了比较评估：监视器显示的质量至少与胶片相当。这些监视器目前正在用于常规的医学解释。
