Multimodality Medical Image Registration Based on Mutual Information and Hybrid Optimization Algorithm
Fan Yang · Journal of Hunan University · 2006
A multimodality medical image registration method based on hybrid optimization algorithm was proposed to solve the problem of the mutual information function containing many local maxima.When dealing with multimodality medical images,we investigated the best matching parameters by applying mutual information as the similarity measure and hybrid optimization algorithm as the search strategy.The registration results showed that the subvoxel accuracy could be achieved and this method can avoid getting into the local optimum.
