I have a 501x501x83 single matrix which contains the vector field of each point. . This vector field is corresponds to image coordinates. x,y,z grid for the vector field in image coordinates. I want to convert them back into vector field specified per voxel, rather than using physical coordinates. While the positive direction is along how voxel indices increase, the values in DVF are in the unit of voxels

How can I do it.

Yours sincerely
