摘要
为了提高数字X线成像(DR)的图像质量,以基于平板探测器校正的DR质量控制管理为研究内容,介绍了DR平板探测器的原理、分类以及由探测器影响图像质量的因素,提出了减小和消除这些因素的校准方法。论证结果表明平板探测器校正在DR质量控制管理中是非常重要的。
To improve imaging quality of X-ray digital radiography system, the quality management and control of DR based on calibration of flat panel detector was investigated. The principle and classification of flat panel detector, and the factors for which flat panel detector degrades image quality were introduced. Methods for flatpanel detector calibration were put forward to minish and eliminate the influences on image quality. Demonstration results indicate that calibration of flat panel detector is very important for quality management and control of DR.
