Type I deforming process and extreme deformation ratio distribution. a, Type I deforming processing. As for Laplacian deformation algorithm, a chosen handle was moved to represent the kick center (blue sphere), a kick direction was defined as outwards from the center of the uterus (red arrow), and a non-stationary area was defined as deformed (the area from yellow belt to the center). b, c local and global deformation, respectively. In each row, the four images show deformation ratios in heat maps from the four indicated views. Warm colors indicate large deformations, and cool colors indicate small deformations as indicated in scales at far right.
