Model Transform with B-spline transformation

Boettcher, Dr. Peter
Dear All
 
We use B-spline registration within Slicer for volumetric image registration. Everything works fine. To avoid interpolation artefacts of surface data on corresponding 3D-models of the volumetric data we would like to apply the found B-spline registration transformaiotn to the 3D-surface models, instead of computing the models based on the registered volumetric data. However it seems that Slicer doesn't apply the B-spline transformation to the 3D-models.
 
Any suggestion would be highly appreciate!
 
Regards, Peter.

Hi Peter -

You are right - we don't have a tool like that (we'll look into it).

Near term, one option to minimize artifacts would be to supersample the
labelmap before transforming it - you should be able to do this with the
Resample Scalar Volume module and picking a smaller pixel spacing.

HTH,
Steve
