| 摘 要： | X光机数字图像增强器是X射线成像系统中的重要一环,而目前常用的X光机数字图像增强器往往存在瑕疵点、信噪比过低等问题。针对噪声问题,提出了一种动态降噪算法,改善了运动环境下的降噪质量。同时,对存在瑕疵点的这一现象,提出了一种检测与校正的算法。最后在自行设计的X光机数字图像增强器样机上将以上两种算法成功实现。

| Abstract: | X-ray digital image intensifier is an important part of X-ray imaging system.However,defective pixels and low signal to noise ratio(SNR) exist in the X-ray digital image intensifiers.Firstly,a dynamic noise reduction algorithm to improve the quality of noise reduction in the moving environment is proposed.Secondly,a detection and correction algorithm for defective pixels is presented.Finally,two algorithms are applied successfully in the self-designed X-ray digital image intensifier prototype. |
