It is effective to measure cerebral surface and for quantitative diagnosis of neonatal and infantile brain diseases. This paper proposes a skull stripping method for the neonatal and infantile brain in T1/ T2 magnetic resonance (MR) images. First, the proposed method discriminates several regions (white matter, gray matter, cerebrospinal fluid, fat, other) from MR images by two typed of Gaussian discriminate. Next, the proposed method initializes the surface model by the obtained white matter region and gray matter region. The surface model deformation process is based on fuzzy rules which translate physicians’ knowledge on the human brain. We applied the proposed method to 26 neonatal and infantile subjects (-4 weeks – 4 years 1 months old). The results showed that the proposed method stripped skull well from neonatal and infantile MR images. |
