Paper Abstract

In this paper, we consider the nature of mental workload and how one might determine whether mental workload effects the potential accuracy of a particular medical image display method. Then we detail observer experiments we have conducted evaluating electronic display of CT images. While detailing these results, we will focus on the evidence we have accumulated which suggests that mental workload has a significant influence on workstation accuracy and interpretation speed. These results suggest that experiments involving interpretation tasks that are very similar to those in the clinic are needed in addition to conventional ROC analysis when evaluating the effectiveness of a new display device or method.
