摘要
冠状动脉的造影图像由于受各种因素的影响,其图像质量的效果不是很好,所以有必要对其进行增强处理,以便于后续的区域分割或者骨架线及血管边缘等血管信息的提取。为了解决这个问题,分别采用了Gabor滤波器和一维旋转高斯函数对造影图像进行了增强,使得造影图像中的冠状动脉比较凸显,有利于进一步对冠状动脉进行分割;为了进一步改进效果,使用一维旋转高斯函数增强后和原图像加影,实验结果表明,改进的算法能够很好地增强造影图像,对临床应用也具有一定的价值。
Coronary angiography images usually are blurry, because of a lot of factors. In order to facilitate following processings-seg- mentation of regions, extraction skeleton line ,edge of vessel and so on,it is necessary to enhance angiography image. To solve this problem,give two methods to enhance angiography image, Gabor filters and rotated one- dimensional Gaussian function, it makes coronary artery more highlight in angiography and it＇s beneficial to further segmentation of the coronary artery. It will be better result to add the angiography image enhanced by rotated one- dimensional Gaussian function to the original image. The experimental results show that this improved algorithm will enhance angiography image very well and it is valuable in clinical diagnosis.
