| Research Abstract |
Although subdural electrode has been used to detect cortical dysplasia, it cannot be applied to allpatients because of invasively . And, it cannot determine the boundary of cortical dysplasia legion. Thisstudy proposed a non-invasive cortical dysplasia detection and region segmentation method usingmagnetic resonance (MR) images. Firstly , this study proposed parenchyma segmentation method inbrain MR images based on fuzzy object model. Secondly , this study proposed a method of estimatingdegree cortical dysplasia using texture features and fractal dimension. The experimental results showedthe proposed method segmented the parenchymal region with a false-positive-volume-fraction of 0.75 %and detected cortical dysplasia with a mean sensitivity of about 90 %.
