Medical Image Elastic Registration Based on Fluid Diffeomorphisms
Chen Zengshen · Beijing shengwu yixue gongcheng · 2005
Fluid diffeomorphisms model is introduced to realize the no-rigid registration based on two control sets of corresponding points for head, liver, spleen, etc. The smooth deformation of constrained image point is got by seeking optimal lagrangian trajectory of control sets, using the mathematic model borrowed from fluid physics, which defines the connection of moving fluid. Experiment results showed that good registration was obtained for both small and large deformation.
