Diode array digital radiography DADR is a method of radiographic imaging that combines the advantages of computer technology with self-scanning linear diode arrays. These digital images are superior to those obtained by film in recording and displaying information in the lightest and the darkest areas of the film, resulting in a balanced image of the entire thorax without compromising detail, and at reduced radiation dose. This is a direct result of the wide dynamic range, high contrast sensitivity, fiber optic coupling, small diode size, short exposure time, and rejection of scattered x-rays of the system coupled with digital post-processing enhancement of the image displayed at 1024 X 1024 pixels.
二极管阵列数字放射摄影（DADR）是一种放射成像方法，它将计算机技术的优势与自扫描线性二极管阵列相结合。这些数字图像在记录和显示胶片最亮和最暗区域的信息方面优于胶片获得的图像，从而在不牺牲细节的情况下获得整个胸部的平衡图像，并且辐射剂量降低。这是该系统具有宽动态范围、高对比度灵敏度、光纤耦合、二极管尺寸小、曝光时间短以及对散射X射线的抑制能力，再加上对以1024×1024像素显示的图像进行数字后处理增强的直接结果。
