Medical image registration using parallel genetic algorithms

Registration of medical image data of different modalities and multiple times is an important component of medical image analysis. A variety of robust and accurate voxel-based approaches have been proposed, and mathematically almost all of them are associated with optimization problems that are highly non-linear and non-convex. This article presents a parallel genetic strategy to attack mutual information based registration. The experimental results show robust registration with high speedup achieved. Furthermore, this method is readily applicable for other voxel-based registration methods.
