Mobile chest radiographs obtained in the intensive care unit with a computed radiography system (one of the digital radiography systems) and a conventional screen-film technique were initially compared in 54 pairs. Features such as the air spaces and interstitium of the lungs, the mediastinum, pulmonary vessels, the tracheobronchial tree, and catheters and other devices were compared in both methods. The computed radiography system demonstrated good visualisation of the mediastinum, pulmonary vessels, the tracheobronchial tree, catheters and other devices. Automatic adjustment of the sensitivity and the wide dynamic range of this system were thought to be responsible for the decrease in the number of retakes even in patients with massive fluid collections. The few artefacts created by digital processing were mostly overcome by a routine use of simultaneous display of two different types of image processing.
最初对54对在重症监护病房使用计算机X线摄影系统（数字X线摄影系统之一）和传统屏片技术获得的移动式胸部X线片进行了比较。对两种方法中的肺部气腔和间质、纵隔、肺血管、气管支气管树以及导管和其他装置等特征进行了比较。计算机X线摄影系统对纵隔、肺血管、气管支气管树、导管和其他装置显示良好。该系统的灵敏度自动调节和宽动态范围被认为是即使在有大量积液的患者中重拍次数减少的原因。数字处理产生的少量伪影大多通过常规同时显示两种不同类型的图像处理得以克服。
