170 patients who had suffered trauma to bones or soft tissues were examined by a digital and a conventional film/screen technique. In addition to "standard" and edge-enhanced images, post-processing was carried out and compared with conventional radiographs. Four radiologists and two surgeons evaluated the compacta, spongiosa, soft tissues, fractures and osteo-synthetic materials as shown on the two systems. The "standard" digital images are inferior to film images, but edge-enhanced images showed definite advantages for demonstrating soft tissues. Evaluation of osteo-synthetic material is limited by the creation of artifacts. Recognition of detail can be significantly improved by using post-processing with optimized parameters.
170名骨骼或软组织受过创伤的患者接受了数字成像技术和传统胶片/屏幕技术的检查。除了“标准”图像和边缘增强图像外，还进行了后处理，并与传统X光片进行比较。四位放射科医生和两位外科医生对两个系统上显示的骨密质、骨松质、软组织、骨折和骨合成材料进行了评估。“标准”数字图像不如胶片图像，但边缘增强图像在显示软组织方面显示出明显优势。骨合成材料的评估受到伪影产生的限制。通过使用优化参数的后处理，细节识别可以得到显著改善。
