The broad, long-term objective of this application is to determine the impact of oculomotor fatigue on diagnostic accuracy during the reading of digitally displayed radiological examinations.This will be accomplished with three specific aims: (1) test whether fatigue reduces detection accuracy and visual search efficiency in static image datasets, (2) test whether fatigue reduces detection accuracy and visual search efficiency in dynamic image datasets, and (3) discover the levels of visual fatigue that are experienced in a variety of situations faced by radiologists in daily practice. Current radiology practice relies increasingly on advanced imaging technology. Not only has this improved access to sub-specialists, yielding greater efficiency and productivity, it has also increased the radiologists' workload significantly. Radiologists now interpret more imaging studies, each containing many more images. This increase in interpretation workload lengthens the time they must spend viewing digital displays and this may adversely affect diagnostic performance. Extensive human factors engineering research has demonstrated that prolonged use of visual display terminals yields oculomotor fatigue, which in turn reduces performance. No research on eyestrain in radiology is available, but a preliminary study demonstrates that radiologists report increasingly severe symptoms of eyestrain, including blurred vision and difficulty focusing, as they read more imaging studies. We propose to evaluate measurable parameters of oculomotor fatigue such as accommodation, vergence, and visual search efficiency and relate them to diagnostic interpretation performance. Diagnostic accuracy will be analyzed with receiver operating characteristic (ROC) methods. Visual search efficiency will be studied by measuring saccade length, decision dwell, and type of search pattern. At the end of this project, we will understand the influence of oculomotor fatigue on diagnostic accuracy and interpretation efficiency. Only by developing a better understanding of the nature of observer error, may we discover effective approaches to reducing the errors.

该应用的广泛、长期目标是确定动眼神经疲劳对 读取数字显示的放射学检查期间的诊断准确性。这将是 完成三个具体目标：（1）测试疲劳是否会降低检测精度和视觉搜索 静态图像数据集的效率，（2）测试疲劳是否会降低检测精度和视觉搜索 动态图像数据集的效率，以及（3）发现在一个人中经历的视觉疲劳程度 放射科医生在日常实践中面临的各种情况。当前的放射学实践越来越依赖于 先进的成像技术。这不仅改善了接触次级专家的机会，而且产生了更多 效率和生产力的同时，也显着增加了放射科医生的工作量。现在的放射科医生 解释更多的影像学研究，每项研究都包含更多的图像。口译工作量的增加 延长了他们观看数字显示器的时间，这可能会对诊断产生不利影响 表现。广泛的人因工程学研究表明，长时间使用视觉 显示终端会导致动眼神经疲劳，进而降低性能。没有关于眼睛疲劳的研究 放射学是可用的，但初步研究表明放射科医生报告的情况越来越严重 当他们阅读更多的影像学研究时，会出现眼睛疲劳的症状，包括视力模糊和聚焦困难。 我们建议评估动眼疲劳的可测量参数，例如调节、聚散度、 和视觉搜索效率，并将它们与诊断解释性能联系起来。诊断准确率 将使用接收器操作特性（ROC）方法进行分析。视觉搜索效率将 通过测量扫视长度、决策停留时间和搜索模式类型进行研究。在这个项目结束时， 我们将了解动眼疲劳对诊断准确性和解释效率的影响。 只有更好地理解观察者误差的本质，我们才能发现有效的方法 减少错误的方法。
