In this paper,wavelet transform is applied to solve CT/MRI medical images registration and fusion.In the process of image registration,an improved algorithm named chaos genetic algorithm is proposed,which is employed to search the global optimization solution in every each of wavelet pyramid based on rigid deformable model.The new algorithm presented in this paper combines traditional genetic algorithms with chaos theory by the full use of the property of ergodicity of chaos movement,expected to improved the performance of genetic algorithms with the help of chaos operator embedded in the algorithm-reducing the number of vain search to speed matching rate,avoiding entrapment in local minimum basin to obtain the result of higher precision.
