Experiments were conducted on a series of chest radiographs to evaluate the effects of mean film density on reader performance. It was found that the false negative is not measurably affected, in agreement with earlier published data. It was also found, however, that the false positive rate increases with increasing film density. The causes and implications of these results are discussed.
对一系列胸部X光片进行了实验，以评估平均胶片密度对阅片者表现的影响。结果发现，假阴性未受到显著影响，这与早期发表的数据一致。然而，还发现假阳性率随着胶片密度的增加而上升。本文讨论了这些结果的原因及影响。
