Digital X-ray photography equipment also arises at the historic moment. DR by charge-coupled Device detector or flat probe X-ray signal can be converted to digital images, has many advantages, Fast imaging, less X-ray dose, high image resolution, wide dynamic range and good imaging continuity, easy operation, for example. This makes DR be widely used in clinical diagnosis, and is the most popular one of the best large equipment in the hospital application. TCL health care system in the process of learning to internships for DR installation and commissioning needs to be an active and serious, prudent and realistic attitude to face. By participating in this process systematic understanding of the DR workflow, enhance DR in the care and maintenance work, and increase the utilization rate of DR, DR and thus enhance the role of diagnosis in the hospital. During the internship through the involvement of Eagle-DR50B production assembly process for this type of instrument's main components include tu
