A 3-D Morphological Algorithm for Automated Labelling of the Cortex in Magnetic Resonance Brain Images

In this paper we describe a new method for auto- matic eztraction and anatomic labelling of the cortical surface in Magnetic Resonance (MR) images of the human brain. Our algorithm consists of a series of morphological operations which automatically find the ortical surface and detect sulci in an MR volume imge. The extracted surface points are labelled as Usulusn or "not sulcus".
