目的:通过DR图像质量控制保证数字摄影的影像质量。方法:根据设备的性能参数和特点,参考厂家说明书和文献资料,对DR系统进行质量监控,并对1200张DR照片进行图像质量分析。结果:DR运行状态良好,所抽查的1 200张照片中合格率达100%,甲级片1 140张,占95%,乙级片36张,占3%,丙级片24张,占2%。结论:保持DR良好的运行状态是获取高质量图像的基础;正确的图像预处理与后处理是获取高质量图像的必要手段;科学的管理,高素质的放射技术员队伍,是DR图像的质量控制与保证,直接数字摄影的图像质量才有保证。
Objective: To ensure the image quality of digital photography through DR image quality control. Methods: According to the equipment performance parameters and characteristics, refer to the manufacturer’s manual and literature data to monitor the quality of the DR system and analyze the image quality of 1200 DR pictures. Results: The DR operated in good condition. The passing rate of 1 200 photos was 100%, 1 140 sheets of Grade A, 95%, 36 sheets of B, 3%, 24 sheets of C, accounting for 2 %. CONCLUSIONS: Maintaining the good running status of DR is the basis for obtaining high-quality images. Correct image preprocessing and post-processing are the necessary means to obtain high-quality images. Scientific management and high-quality radiological technicians are the quality control of DR images And assurance, direct digital photography image quality is guaranteed.
