Abstract:

In order to improve the performance of the 3D medical image non-rigid registration method, a new LBM (Lattice Boltzmann Method) craniocerebral MR 3D medical image non-rigid registration method is proposed. The 3D medical image registration process is converted into the flow process of the viscous fluid, the deformation force driving pixels are generated by using two-image gray level difference, and the pixels deformation trajectories are simulated under the control of external force by use of the LBM equation. The LBM equation of the compressible viscous fluid with a control force is set up, meanwhile the boundary conditions and the differential homeomorphism conditions are defined. Experimental results show that this method has the better performance than the similar methods.

Key words: lattice Boltzmann method, medical image, non-rigid registration, viscous fluid, diffeomorphic
