Receiver Operating Characteristic (ROC) analysis in the field of visual imaging has hitherto dealt with the performance of imaging modalities, system displays, or individual readers. This study combines previously established interlaboratory survey techniques with ROC concepts to evaluate selected indices of group discrimination and of group decision criteria in a quantitative and comparative manner. One hundred forty-two subscribers to the College of American Pathologists Phantom-Imaging Series performed a series of visual detection tasks on a fabricated radioactive phantom image. Results suggest that group performance may be legitimately assessed by ROC analysis if the variables of system modality, image display, and cases are controlled, and the number of trials is sufficiently large. The latter condition may be fully satisfied through interlaboratory survey techniques that utilize currently existing peer groups.
视觉成像领域的接收者操作特征（ROC）分析迄今一直关注成像模式、系统显示器或个体阅片者的性能。本研究将先前建立的实验室间调查技术与ROC概念相结合，以定量和比较的方式评估群体辨别和群体决策标准的选定指标。142名美国病理学家学会幻影成像系列的订阅者在一张伪造的放射性幻影图像上执行了一系列视觉检测任务。结果表明，如果系统模式、图像显示和病例等变量得到控制，且试验次数足够多，那么通过ROC分析可以合理地评估群体性能。利用现有同行群体的实验室间调查技术可以充分满足后一个条件。
