MRI-PET medical image fusion has important clinical significance. Medical image fusion is the important step after registration, which is an integrative display method of two images. The PET image shows the brain function with a low spatial resolution, MRI image shows the brain tissue anatomy and contains no functional information. Hence, a perfect fused image should contains both functional information and more spatial characteristics with no spatial & color distortion. The DWT coefficients of MRI-PET intensity values are fused based on the even degree method and cross correlation method The performance of proposed image fusion scheme is evaluated with PSNR and RMSE and its also compared with the existing techniques.
