摘要
随着图像存储与传输系统(PACS)的快速发展,图像识读已从传统的胶片和灯箱为主的硬拷贝阅读模式向以计算机和显示器为主的软拷贝阅读模式转变。指出了软阅读的认知载体——医用单色显示器的性能参数(包括亮度、分辨率和对比度等)是影响放射诊断系统效能的一个非常重要的因素,应用ROC曲线理论可以方便地对这种影响进行定量评价,并为选择合适的显示器提供了可靠的科学依据。
With the rapid development of Picture Achieving and Communication System （PACS）, the interpretation of medical images has been changing rapidly from a procedure based on films and light boxes to one based on computers and medical displays. The function parameters of Soft-Copy Reading carriers——medical grayscale display play an important part in radiodiagnosis because they can greatly influence the quality of medical image. It is very easy for quantitative assessment of this influence by using ROC curve theory, and it can direct hospital to select suitable medical display.
