Part III: Inhomogeneity Correction

The inhomogeneity correction procedure is based on the result of the previous step (the so-called presegmentation of the white matter). As soon as this step has been done, one has to open the V16 tools dialog in the Volumes menu.

The only thing we have to do after the proper presegmentation of the white matter has been performed is to click the “Presegmentation-based” button.


The resulting (corrected) VMR file will not be automatically saved, so one should do this right away. For reasons of comparison, it is helpful to use a new name for the corrected VMR file (I add an “_ic” to the end of the filename – this way the new file is easy to find).
