图像信息融合与医学图像综合显示

讨论了医学图像计算机断层摄像技术与核磁共振的融合问题．分析了计算机断层摄像技术与核磁共振的成像机理，依据期望的融合结果，提出了一种新的基于小波变换的系数取大融合算法．将已匹配的计算机断层摄像技术与核磁共振图像首先分别进行小波变换，然后比较相应尺度上的小波系数。采取区域系数取大准则，构造新的小波系数，最后进行小波反变换，获得融合图像，既可清晰地表现骨组织信息，又可清晰地表现软组织信息．

Image information fusion and synthesis display of medical images

A new CT and NMR medical image fusion method is described. According to the expected fusion results, a new wavelet transform-based maximum-chosen fusion method is presented after a detailed analysis of the basic imaging principles of CT and NMR. The wavelet transform of the matched CT and NMR are taken first, and then a combined wavelet coefficient is obtained after comparing the same scale wavelet coefficients of CT and NMR and choosing the largest one. The fusion image can be obtained after making the inverse wavelet transform of the combined wavelet coefficient. The image obtained clearly displays the bone and soft tissues in one image.
