While eye tracking research in conventional radiography has flourished over the past decades, the number of eye tracking studies that looked at multislice images lags behind. A possible reason for the lack of studies in this area might be that the eye tracking methodology used in the context of conventional radiography cannot be applied one-on-one to volumetric imaging material. Challenges associated with eye tracking in volumetric imaging are particularly associated with the selection of stimulus material, the detection of events in the eye tracking data, the calculation of meaningful eye tracking parameters, and the reporting of abnormalities. However, all of these challenges can be addressed in the design of the experiment. If this is done, eye tracking studies using volumetric imaging material offer almost unlimited opportunity for perception research and are highly relevant as the number of volumetric images that are acquired and interpreted is rising.
在过去几十年里，传统放射成像中的眼动追踪研究蓬勃发展，但针对多层图像的眼动追踪研究数量却相对滞后。该领域研究匮乏的一个可能原因是，传统放射成像背景下使用的眼动追踪方法无法直接应用于容积成像材料。容积成像中与眼动追踪相关的挑战尤其涉及刺激材料的选择、眼动追踪数据中事件的检测、有意义的眼动追踪参数的计算以及异常情况的报告。然而，所有这些挑战都可以在实验设计中得到解决。如果做到这一点，使用容积成像材料的眼动追踪研究为感知研究提供了几乎无限的机会，并且随着获取和解读的容积图像数量不断增加，其相关性也非常高。
