对于高的空间分辨率的射线照相法的应用而言,在下一世纪里,似乎要求更好的底片作为记录介质。但要追求高效率时,用人工解释模拟量的底片图象则具有主观成分,所以对底片上的信息进行数字化处理,则可做到更加客观和定量的评定。这些评定可能是金
For high spatial resolution radiography applications, in the next century it seems that a better negative is required as the recording medium. However, in pursuit of high efficiency, artificial interpretation of an analog negative film has a subjective composition. Therefore, a more objective and quantitative evaluation can be done by digitizing the information on the negative film. These ratings may be gold
