Module Description

Creates a BSpline transform from a displacement field defined at scattered points by using the Multi-level BSpline interpolation algorithm.


Use Cases

1. Create a B-Spline transform based on two sets of fiducials.

2. Create a B-Spline transform based on two sets of points read from files. These files can contain the initial and deform configurations for a biomechanics-based FEM or mesh-free registration. The resulting B-Spline transform can be used to warp 3D images, a process which is very time consuming if spatial interpolation is performed using the mesh [1].
