Demonstration of XCAT female phantom results. (a) Original image (Phase 1); (b) target image (Phase 4); (c) differences between deformed and target images at the beginning of optimization; (d) differences between deformed and target images at iteration 5; (e) differences between deformed and target images at iteration 100 (end of the optimization); (f) final deformed image from Phase 1.
