De-scalping
the brain data is a very critical step in MRI data post-processing and
analyzing. Many applications related to brain MRI either require, or benefits
from the ability to accurately segment brain from the non-brain tissue. Here
we present a simple, fast and robust technique for brain de-scalping. Current
de-scalping procedure utilizes lipid ratio map obtained from MRI images
without and with lipid saturation pulse, which are normally acquired at
clinical scanners. MRI whole brain
data from different clinical scanners was successfully de-scalped using
current procedure.
