研究了原型 CRT 工作站的可操作性和室内照明对观察者表现的影响。在CRT工作站读取CT图像作为日常工作的实验中，在100勒克斯的室内照度下分析一张CT图像所需的平均时间比在胶片观察盒上分析的时间要长。出现延长的主要原因是根据观察者的需要检索和排列图像所需的时间较长，以及两个 CRT 监视器上同时显示的图像数量的限制。在使用成像板的计算机X射线照相CRT图像检测肺部小结节的ROC研究中，170 lux左右的照度显示出最佳结果，与480 lux相比具有统计学显着性差异（P<0.05）。除了放射科医生的视觉表现外，还必须考虑房间照明，因为它会影响观察者的表现和诊断效率。
The effects of the operability of the prototype CRT workstation and room illumination upon observer's performance were studied. In the experiment of reading CT images as a routine daily work at the CRT workstation, the average time required to analyse one CT image under a room illuminance of 100 lux was longer than that on the film viewbox. Prolongation occurred due mainly to the longer time required to retrieve and to arrange images as observers desired, and the limitation to the number of images simultaneously displayed on two CRT monitors. In the ROC studies to detect small pulmonary nodules on CRT images of computed radiography with imaging plate, illuminance around 170 lux showed the best result and a statistically significant difference (P< 0.05) as compared with that of 480 lux. In addition to the radiologist's visual performance, room illumination must also be taken into consideration as it influences the observer's performance and diagnostic efficiency.
