Abstract (in Japanese) (See Japanese page) 
(in English) Because most of refractory patients with focal cortical dysplasia are candidate for epilepsy surgery, it is important to detect cortical dysplasia of epileptic children. This paper proposes an automated method for detecting cortical dysplasia using magnetic resonance (MR) images. To evaluate the cerebral cortex layer, the proposed method extracts texture features of a region which is perpendicular to the cerebral surface. Cortical dysplasia degree (C.D.D.) is estimated by using support vector machine (SVM). The experimental results for two subjects showed that the proposed method detected cortical dysplasia lesions with a mean sensitivity of 68.6 %, a mean specificity of 67.0 %, and a mean efficiency of 68.1 %.
