新型 17' X 17' 即时直接数字平板探测器已开发出来，以满足一般放射线照相的需求。在回顾了一般放射线照相需求的几个关键方面（X射线能量范围和相关测量条件、系统集成和系统操作）后，我们描述了基于碘化铯/非晶硅的新型探测器技术，并给出了测量结果（MTF、DQE稳定性）。我们将新探测器的性能与现有技术（胶片/屏幕组合、存储荧光粉设备）以及其他平板解决方案（Selenium）进行比较。我们的结论是，CsI/a-Si 技术现在是最适合满足普通放射线照相需求的技术，这意味着迄今为止一直使用胶片进行的各种检查（胸部、腹部、骨骼、四肢……）。
A new 17' X 17' immediate direct digital flat panel detector has been developed to fit the needs of General Radiography. After reviewing a few key aspects of the General Radiography needs (X-ray energy range and associated measurement conditions, system integration and system operation), we describe the new detector Cesium Iodide/Amorphous Silicon based technology, and give measurement results (MTF, DQE stability). We compare the new detector performance to existing technologies (film/screen combination, storage phosphor devices) and also to other flat panel solutions (Selenium). We conclude that the CsI/a-Si technology is now the best suited one in order to fit the needs of General Radiography, this means all kinds of examinations (chest, abdomen, bones, extremities. . .) which have been up to now done using films.
