Realization of Medical Image Fusion Based on Wavelet Transform
基于小波变换的医学图像融合技术的实现

Purpose: In this paper,we accomplish image fusing of CT and MRI images using wavelet.Methods: As wavelet is of comfortable effect in image fusing,more and more researchers are working on it.And,in Matlab,there is a toolbox called Wavelet Toolbox 3.0,with which we can finish some image fusing simply.With some drawbacks,the toolbox works not so well with some kinds of image pairs,such as a picture of ct and a picture of pet,if the pet image is gray image instead of a counterfeit color image.Then the resulted image if of bad quality with low-lying effect.In order to achieve a good result of image fusing we should think about many aspects of it and realize them by program.Result: We strive to fulfill the program and compare the result to what we have got by toolbox.And the effect is comfortable.Conclusion: By wavelet toolbox,some simple medical image fusing can be accomplished.But with the development of technique of image fusing and the deepening of complexity of medical images,the process of image fusing would be more complex especially those images rooted from abdomen and chest.So more methods must be called for rather than toolboxes.
