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.

本申请的广泛、长期目标是确定眼疲劳对 在数字显示放射学检查的阅读过程中的诊断准确性。这将是 完成了三个具体目标：（1）测试疲劳是否会降低检测精度和视觉搜索 测试疲劳是否会降低检测精度和视觉搜索 效率的动态图像数据集，和（3）发现的视觉疲劳的水平，在经历了一个 放射科医生在日常工作中面临的各种情况。目前的放射学实践越来越依赖于 先进的成像技术。这不仅改善了获得次级专家的机会， 除了提高效率和生产力外，亦大大增加了放射科医生的工作量。放射科医生现在 解释更多的成像研究，每个研究包含更多的图像。口译工作量的增加 延长了他们必须花在观看数字显示器上的时间，这可能会对诊断产生不利影响。 性能广泛的人为因素工程研究表明，长期使用视觉 显示终端产生眼疲劳，这又降低了性能。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，放射科医生报告说， 随着他们阅读更多的成像研究，他们会出现眼睛疲劳的症状，包括视力模糊和难以聚焦。 我们建议评估眼疲劳的可测量参数，如调节，聚散， 和视觉搜索效率，并将它们与诊断解释性能相关联。诊断准确性 将采用受试者工作特征（ROC）方法进行分析。视觉搜索效率将是 通过测量扫视长度、决策停留时间和搜索模式的类型来研究。在这个项目结束时， 我们将了解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， 减少错误的方法。
