摘要：
An approach to the problem of multimodality medical image fusion is proposed, using two-dimensional discrete wavelet transform(2-D DWT). Local image fusion mechanism employing 2-D periodic DWT is also presented, which decreases the calculation time and space cost. To evaluate the fusion result, mutual information (MI) is employed as a performance measurement. The experiment results demonstrate that the fusion scheme of this study is very well suited for clinical applications, especially for treatment plan when complementary information is needed.
