Medical image fusion provides complementary information of the different modal images for diagnosis, surgery design and evaluation.Therefore, complete unit orthogonal bases with second degree were obtained by orthonormalizing first order Taylor expansion of Gauss function.The biorthogonal multiwavelet filter with third order vanished moment was designed with the bases as scale functions.First CT and MRI medical images were discomposed with the designed filter.Then the fused scheme with local energy weight was modified on the multilevel.Finally the fused image was obtained with the scheme.The result indicated the fused image preserved the details of each input image successfully.It was more effective than the general fused scheme.The designed filter can be used to fuse medical image efficiently, and is a little effective than DGHM multiwavelet
