One of the most common MRI (Magnetic Resonance Imaging) use is a brain visualization. Brain anatomy is highly complicated so it might be difficult to extract only these structures which have diagnostic value. In a consequence it is necessary to develop and apply most efficient brain segmentation algorithms. One of the first steps in case of neurological MRI analysis is skull stripping. It involves removing extra-meningeal tissue from the head image, therefore it is essential to find the best method to determine the brain and skull boundaries. In T1-weighted images, cerebrospinal fluid (CSF) space and skull are dark, that is why the edges between the brain and the skull are well-marked but even strong edges might be unsettled because of finite resolution during MRI acquisition or the presence of Other anatomical partial structures within the brain (connections between the brain and optic nerves or brainstem). There are many ways to perform this operation, none of them are as good as they are to standard proceedings. In many cases, there are limitations associated with the development environment, license and images that hinder skull stripping without specialized software. Proposed method is free of these constraints. It is based on application of morphological operations and image filtration to enhance the result of the edge detection and to provide better tissues separation.
