I am trying to understand what is exactly happening when I use the crop volume function with the isotropic spacing and B-spline interpolation flags on. This is mostly for a discussion section on a publication and my own sanity
The isotropic spacing is ensuring that the shape of the voxels of the new volume are almost identical in size (say +/- 5-10%). And, in the directions in which the difference is greater than a set limit, say this 5-10%, a B-Spline interpolation is used to approximate the voxels in between???
Is this correct? close?
