RECONSTRUCTION OF CENTRAL CORTICAL SURFACE FROM BRAIN MRI IMAGES: METHOD AND APPLICATION

Reconstruction of the geometric central surface of the human cerebral cortex is an important means to study the structure and function of the brain cortex. In this paper, we propose a novel method based on an elastic deformable transform vector field to drive a deformable model for the reconstruction of the central surface of the brain cortex. In addition, simulated brain cortexes are generated to evaluate this method. We report the evaluation results obtained from ten subjects to show the effectiveness of our approach. We applied the central cortical surface reconstruction method and the hybrid cortical surface registration method to detect simulated brain atrophy. Our results indicate that the central cortical surface has much better sensitivity in detecting simulated atrophy than traditionally used inner or outer cortical surfaces
