[Insight-users] BSpline Deformable Registration

[Minjie Wu]

Hello All,

I am using BSpline Registration for 3D brain image alignment. The warped
results look ok, but I am more interested in a constrained deformable
registration, such as allow the deformation only in one direction (could

be x, or y, or z-direciton).

I wonder if it is possible to have BSpline deformable registration with
less deformation flexibility, such as allowing deformation in one
direction only.

Or if there is any other deformable transformations in ITK have such

constrained-deformation property?

Any suggestion is appreciate. Thank you very much for your help.
