The Region Growing method, which is used in most of the segmentation, has problems that a leakage and a few isolated regions are generated in 2-dimensional domain. Therefore, we propose an efficient brain segmentation method for improving those problems. Our method has four step : 1) edge detection, 2) selecting ROI, 3) Region Growing with restricted processing area every slice, 4) two-way Region Growing. We applied our method to the T1-weighted MR image data of a patient. As the result, we have improved the leakage and the insufficiency of the extraction of brain data.
