CT胶片感光性能和影像质量控制的研究

Study on Film Sensitivity and Image Quality Control in Computed Tomography

作者通过对进口、国产５种性能各异的ＣＴ胶片，在多幅相机上采用不同亮度和对比度进行试验后，选择出合适的感光条件，使ＣＴ图像质量能达到诊断要求。同时提出，图像质量指标的控制范围。

In this study,the authers proposed the optimal radiographic parameters for 5 brands of CT films both imported and local,by adjusting brightness and contrast of multiformat cam-era to yield good diagnostic images.The range for image quality control was also suggested.
