摘要
目的:通过对CT轴位的心脏冠脉钙化图像进行处理,与双源螺旋CT心脏扫描三维重建后的诊断对比,探讨利用轴位图像判断冠脉钙化的实际程度。方法:使用数字图像增强算法中的分段非线性拉伸法,对多个不同患者和不同部位的冠脉钙化图像进行处理,得到结果后,与双源螺旋CT心脏扫描后的三维图像的诊断结果进行对比分析。结果:通过对不同患者和不同部位的CT轴位图像进行钙化图像处理,所得诊断结果与利用三维图像所得诊断结果相似。结论:基于非线性灰度拉伸的图像处理方法,对于通过轴位图像来分析冠状动脉钙化程度具有一定的应用价值。
Objective To investigate the possibility of judging the coronary calcification degree using the CT axial images,comparing the processing results of CT axial images of calcified coronary artery and the 3-D reconstruction images acquired by double-source spiral CT.Methods Non-linear stretching method of digital image enhancement algorithm was used to process the axial images of calcified coronary artery of different patient and location.The outcome was contrastively analyzed with that of 3-D images by double-source spiral CT.Results The outcome by processing the images of 12 groups of patients was similar with the diagnosis made by 3-D images.Conclusion Non-linear stretching method of digital image enhancement algorithm,by analyzing the CT axial images,is of certain application value in judging the calcification degree of coronary artery.
