yes, it is zero padded. Note also that it is downsampled to be 8 bits/voxel from whatever it was.

Hi,

The voxel dimensions are indeed 1x1x1. Does embedding mean that the 256x256 matrix is form from zero-padding?

Thanks! Trina

Quoting Bruce Fischl fischl@nmr.mgh.harvard.edu:

...

it depends on the voxel dimensions. If they are 1x1x1 we just embed it, otherwise we use trilinear interpolation.

cheers, Bruce

Hi All,

I have a few scans that were done with a field of view of 200. I was wondering how freesurfer extrapolates that to a 256 by 256 by 256 matrix.
