摘要 本文讨论了医学图像CT与NMR的融合问题。由于骨骼组织仅能在CT中清晰显示,而软组织仅能在NMR中清晰显示,所以CT与NMR图像各自都不能同时清晰显示骨骼组织和软组织。在分析了CT与NMR图像成像机理的基础上,提出了一种基于多小波变换的融合方法。它可将CT与NMR图像进行有效的综合。所获得的融合图像,可同时清晰地显示骨组织和软组织信息。 The medical CT and NMR image fusion problem is discussed. For bone can only be clearly displayed on CT image, while soft tissue on NMR image, So CT and NMR images respectively can not clearly display bone and soft tissue at the same time. A multiwavelet transform based fusion method is presented after the analysis of imaging principles of CT and NMR images. This method can efficiently integrate CT and NMR images. The fused image obtained can clearly display bone and soft tissue at the same time.
