[Insight-users] How to set the special region of BSpline Registration in ITK

[Luis Ibanez]

Hi Linzhe,

There are two things that you want to do in that case:

1) Set the FixedImageRegion() of the registration method
    to use only the region of the image that you are interested on.

and

2) When defining the BSpline grid, use that region as a base,
     instead of the largest possible region of the image.

    That is, for example, set the BSpline grid origin in the corner
    of your image region of interest, instead of the largest possible
     region.
