Postmortem images of seven premature and term newborns, acquired with various conventional screen-film combinations and by a digital technique with appropriate radiation exposures, were compared. Images without and with simulated pathology were used in this study. With electronic manipulation of the computed radiographs we obtained well-balanced images with good contrast, and in many cases the artifacts were better visualized than with the conventional screen film. However, in our study no significant dose reduction for this young age group was possible with the digital technique compared with conventional screen film.
对七名早产和足月新生儿的尸检图像进行了比较，这些图像是通过各种传统的增感屏-胶片组合以及采用适当辐射剂量的数字技术获取的。本研究使用了无模拟病变和有模拟病变的图像。通过对计算机射线照片进行电子处理，我们获得了对比度良好、平衡度佳的图像，而且在许多情况下，与传统增感屏-胶片相比，伪影能更清晰地显现。然而，在我们的研究中，与传统增感屏-胶片相比，数字技术无法使这个年龄段的受检者实现显著的剂量降低。
