In modern radiology departments, the possibility of image interpretation in a PACS environment has grown. A reduction in stress and an increase in work efficiency at the CRT viewing station are required, and much progress has been made toward establishing the optimal display format from the viewpoint of ergonomics. This study evaluated the effectiveness of three kinds of display methods for MR image interpretation using an eye-tracking device. Seven radiologists interpreted head MR studies using a single monitor (17-inch, 1,024x1,280) in the 4 images/screen display format. Three paging modes were compared : (1) mode A : rapid paging only ; (2) mode B : multiple image series display at the same slice position with consecutive rapid paging ; (3) mode C : simultaneous display of multiple series, but each image series were browsed independently. Using an eye-mark camera, the radiologist's point of fixation and the duration of fixation were recorded during actual image interpretation. In mode A,the duration of fixation was short, and the points of fixation were distributed randomly over the visual field. In mode B,the points of fixation were clustered chiefly on a specific image series. In mode C,the points of fixation were not clustered on a specified series, but the duration of viewing the T2 series was relatively long. The total tracing area in mode B and C was smaller than that in mode A.With regard to visual search patterns in the multiple series display mode, radiologists started MR image interpretation by scanning a certain image series and fixated on several images which were attractive. Subsequently, other image series were viewed for analyzing abnormalities detected on the initially interpreted series. Multiple series display, in which selected key series of slices could be viewed effectively, was found to be suitable for MR image interpretation.

在现代放射科中，PACS环境中的图像解释的可能性已经增长。要求在CRT观察站减少压力和提高工作效率，从人机工程学的观点出发，在建立最佳显示格式方面已经取得了很大的进展。本研究使用眼动仪评价了三种显示方法对MR图像解释的有效性。7名放射科医师使用单个显示器（17英寸，1，024 x1，280）以4张图像/屏幕显示格式解读头部MR研究。比较了三种分页模式：（1）模式A：仅快速分页;（2）模式B：在同一切片位置显示多个图像系列，并连续快速分页;（3）模式C：同时显示多个系列，但独立浏览每个图像系列。使用眼标照相机，在实际图像判读期间记录放射科医师的注视点和注视持续时间。在模式A中，注视持续时间短，并且注视点在视野上随机分布。在模式B中，注视点主要聚集在特定的图像系列上。在模式C中，注视点没有聚集在指定的系列上，但是观看T2系列的持续时间相对较长。模式B和C中的总跟踪面积小于模式A中的总跟踪面积。关于多系列显示模式中的视觉搜索模式，放射科医师通过扫描某个图像系列开始MR图像解释，并注视几个有吸引力的图像。随后，查看其他图像系列，以分析在最初解释的系列上检测到的异常。多系列显示，其中选定的关键系列切片可以有效地查看，被认为是适合MR图像的解释。
