Radiologists perform many 'visual search tasks' in which they look for one or more instances of one or more types of target item in a medical image (e.g. cancer screening). To understand and improve how radiologists do such tasks, it must be understood how the human 'search engine' works. This article briefly reviews some of the relevant work into this aspect of medical image perception. Questions include how attention and the eyes are guided in radiologic search? How is global (image-wide) information used in search? How might properties of human vision and human cognition lead to errors in radiologic search?
放射科医生会执行许多“视觉搜索任务”,即在医学图像中寻找一种或多种类型目标项目的一个或多个实例(例如癌症筛查)。为了理解并改进放射科医生执行此类任务的方式,必须了解人类“搜索引擎”的工作原理。本文简要回顾了一些关于医学图像感知这一方面的相关研究。问题包括在放射学搜索中注意力和眼睛是如何被引导的?搜索中如何使用全局(全图像)信息?人类视觉和认知的特性如何导致放射学搜索中的错误?
