摘　　要：自能量减影技术开发以来 ,影像噪声一直是影响图像质量的关键因素之一。因减影后的图像噪声过高无法应用于临床 ,经科研人员的实验研究 ,终以噪声重复过滤消除 (FINE)技术解决该难题 ,使图像质量得到了明显提高。The Imaging noises are one of the critical factors which weaken the image quality since the energy subtruction developed. The energy subtraction images can not be applied in clinical practices because of the high imaging noises. The related technologists,therefor, have accomplished numerous researches, and developed the filter interactive noise elimination technique. After that the ES imageing quality has been improved dramatically.
