I have a general question about how Slicer handles and applies deformable registration files that are exported from TPS software with respect to grids.
I would like to apply a deformation vector field (DVF) to a dose volume. My question is,
If I apply the DVF to a dose volume within Slicer’s Transform module (i.e., Apply Transform -> Harden Transform) what happens to the grid spacing of the warped dose volume?
Is it still uniform (through some internal re-sampling?) or is the grid of the dose volume ‘smeared’ out in a warped non-uniform fashion?
For reference, here is the transform information of my Deformable Registration Grid
As an extra question 1)
What is the difference between using the Transforms module or a Re-sampling module when applying a DVF to a dose volume?
Extra question 2)
What is the difference between applying a ‘Displacement field’ transform and a ‘b-Spline’ transform to a dose volume?
