If the problem with the 3T inhomogeneity is that the variations are
stronger than at 1.5T (bias has more high frequencies), maybe you could
try our method. It is a Matlab script to correct surface coil images:

I hope this could help

Subject: [SPM] Inhomogeneity in 3T images
Hi All: I have a question regarding the use of images acquired on a
3-T scanner for use in VBM (SPM2). Can anyone suggest the best method
to correct for inhomogeneity in these images? I have tried Kalina
Christoff's script (from the spm extensions site) but to no avail.
The script worked, but it did not improve my VBM results.
