A method of creating an image of brain fibers includes exposing the brain fibers to a magnetic resonance imaging process. The data acquisition from the magnetic resonance imaging includes the acquisition of diffusion-weighted, images that are later employed to calculate an apparent diffusion constant at each pixel along more than six axes. The data is introduced into a microprocessor which calculates six variable in a diffusion tensor and obtains a plurality of eigen values and eigen vectors. This may be accomplished by employing a diffusion sensor which is diagonalized to obtain three eigen values and three eigen vectors with the six values being subjected to further microprocessing to generate imaging information representing the properties of the fibers. The process in a preferred embodiment includes the initiation of fiber tracking by selecting a pixel for initiation of the same, connecting of pixels and effecting a judgement regarding termination of the pixel tracking in each direction based upon the randomness of the fiber orientation of the adjacent pixels.
