Image information fusion and synthesis display of medical images

NAN Yan,YANG Wan-hai,LI Yong-zhao(School of Electronic Engineering, Xidian Univ., Xi′an710071, China)  
A new CT and NMR medical image fusion method is described. According to the expected fusion results, a new wavelet transform-based maximum-chosen fusion method is presented after a detailed analysis of the basic imaging principles of CT and NMR. The wavelet transform of the matched CT and NMR are taken first, and then a combined wavelet coefficient is obtained after comparing the same scale wavelet coefficients of CT and NMR and choosing the largest one. The fusion image can be obtained after making the inverse wavelet transform of the combined wavelet coefficient. The image obtained clearly displays the bone and soft tissues in one image.
