A Parallel Nonrigid Registration Algorithm Based on B-Spline for Medical Images
Figure 4
The registration results for chest images using the CPU-based and GPU-based implementation, respectively. (a) The reference image; (b) the moving image; (c) the difference result of the two images before registration; (d)–(f) are, respectively, the best deformation mesh, the moving image subjected to the best deformation, and the differential result after registration using CPU-based implementation; (g)–(i) are the best deformation mesh, the moving image subjected to the best deformation, and the differential result using our GPU-based implementation.
