<pre>Hello All,<br><br>I am using BSpline Registration for 3D brain image alignment. The warped<br>results look ok, but I am more interested in a constrained deformable<br>registration, such as allow the deformation only in one direction (could
<br><br>be x, or y, or z-direciton).<br><br>I wonder if it is possible to have BSpline deformable registration with<br>less deformation flexibility, such as allowing deformation in one<br>direction only.<br><br>Or if there is any other deformable transformations in ITK have such
<br><br>constrained-deformation property?<br><br>Any suggestion is appreciate. Thank you very much for your help.<br>-Minjie<br></pre>
