The Skull Stripping Problem in MRI Solved by a Single 3D Watershed Transform

A robust method for the removal of non-cerebral tissue in T1-weighted magnetic resonance (MR) brain images is presented. This procedure, often referred to as skull stripping, is an important step in neuroimaging. Our novel approach consists of a single morphological operation, namely a modified three-dimensional fast watershed transform that is perfectly suited to locate the brain, including the cerebellum and the spinal cord.
