对直接数字化摄影(Direct Radiographpy,DR)图像质量进行了分析,提出了如何获取DR系统最佳影像方法的问题。通过应用X线摄影体位设计、选择数字摄影条件参数、使用图像后处理工作站、匹配激光相机、合理的日常维护和保养机器、设定机器所处环境因素的方法,彻底解决了影响DR图像质量的问题。使获取DR系统最佳影像的方法变得更加简单方便,同时也为临床提供了很好的帮助,效果显著。 The image quality of Direct Radiographpy (DR) is analyzed, and how to get the best image of DR system is put forward. Through the application of X-ray photography position design, the choice of digital photography conditions parameters, the use of image processing workstation, matching laser cameras, reasonable maintenance and routine maintenance of machinery, set the machine in which environmental factors, completely solve the impact of DR image quality problem. DR system to obtain the best image of the method to become more simple and convenient, but also for the clinical has provided a very good help, the effect is significant.
