A Parallel Nonrigid Registration Algorithm Based on B-Spline for Medical Images

Figure 5

The registration results for brain images using the CPU-based and GPU-based implementation, respectively. (a) The reference image; (b) the moving image; (c) the difference between the reference and moving image before registration; (d)–(f) are, respectively, the best deformation, the moving image transformed with best deformation, and the difference image after registration using the CPU-based implementation; (g)–(i) are, respectively, the best deformation, the transformed moving image, and the difference after registration using our GPU-based implementation.
