Magnetic resonance imaging (MRI) is a very popular, non-invasive medical diagnostic technique providing images of the human body. The method, commonly used in clinics and hospitals all over the world, is based on the magnetic properties of hydrogen atom and its interactions with magnetic field. MR images show differences in water content and distribution in various body tissues. Even different tissues in the same organ, such as the gray and white matter in brain, can easily be distinguished. For a precise analysis of the images obtained in the result of MR examination, special computer applications are used. The paper presents the basis for the magnetic resonance imaging and description of the method of brain segmentation which could be a useful software tool in daily medical diagnosis practice.
