Initial clinical results are described for a new method of digital radiography based on high-detail self-scanning linear diode arrays which overcome many of the limitations of present film or other digital methods. The technique uses a fan-shaped x-ray beam to produce a nearly scatter-free image on a phosphor strip that is fiber-optically coupled to six self-scanning arrays of light-sensitive diodes spaced 0.025 mm, thus providing 6,144 discrete sensors across the field of view. Because these diodes have a greatly expanded dynamic range and operate at very low noise, it becomes possible to visualize small density differences or contrast below 1% both in the light and dark areas of the image. Because of the efficiency of detection and display, radiation doses can be reduced for a given information content. Our preliminary clinical studies have shown to broad application of our method in examining the chest and abdomen and in performing intravenous digital arteriography.
本文描述了一种基于高细节自扫描线性二极管阵列的数字射线照相新方法的初步临床结果，该方法克服了当前胶片或其他数字方法的许多局限性。该技术使用扇形X射线束在磷光体带上产生几乎无散射的图像，该磷光体带通过光纤耦合到六个间距为0.025毫米的自扫描光敏二极管阵列，从而在整个视野范围内提供6144个离散传感器。由于这些二极管具有大大扩展的动态范围并且在非常低的噪声下工作，因此可以在图像的亮区和暗区中可视化小的密度差异或低于1%的对比度。由于检测和显示的效率，可以在给定信息含量的情况下降低辐射剂量。我们的初步临床研究表明，我们的方法在胸部和腹部检查以及静脉数字血管造影中具有广泛的应用。
