Chapter 47. Deformable Volumetric Registration Using B-Splines
James Shackelford, Nagarajan Kandasamy and Gregory Sharp
This chapter shows how to develop a B-spline-based deformable registration algorithm within the single instruction multiple thread (SIMT) model to effectively leverage the large number of processing cores available in modern GPUs. We focus on improving processing speed without sacrificing quality to make the use of deformable registration more viable within the medical community. Performance results on a Tesla C1060 show that for large images, our GPU algorithm achieves a speedup of 15 times over a single-threaded CPU implementation. Moreover, the CPU and GPU versions achieve near-identical registration quality.
