I need however do do some deformable registration on a single slice extracted from a volume and then use this 2D displacement field (pasted into 3D image) on the full 3D volume; in essence to just warp one particular slice of that volume</div>
<div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px"> Deformable registration however requires 4 voxels in the third dimension to operate which I believe from memory is because the deformable registration uses a Gaussian filter during it's operation. This is why I am using just a 2D slice with zero dimensions in the third plane and then attempting to recast this as a 3D volume dispalcement field. Would it be adequate to resample my initial volume to get x4 the voxels in the in slice direction and then perform deformable registration on this now 3D chunk of data?</div>
