Dear SPMers,
I want to get a voxel displacement map (.vdm file) to use this map during realign unwarp to correct for static B0 field inhomogenities.
During some runs on a Siemens VERIO we only measured the gradient field map phase difference image and not a magnitude image.
Is it possible to obtain a .vbm file from the phase difference image only? Is this realisable also with the FiledMap toolbox (http://www.fil.ion.ucl.ac.uk/spm/toolbox/fieldmap/)?
Kind regards,
