DTI allows the distinction of matter anatomy, because the measured diffusion is stronger in parallel with boundaries; such as for example cell membranes. For the reconstruction of the course of neuronal fibers, fiber tracking methods were developed. Classical methods cannot handle voxels that contain multiple fiber orientations, for example fiber crossings. A new diffusion simulation based fiber tracking method that uses time-of- arrival maps to reconstruct the tracts is presented. This method is able to solve problems of the commonly used methods. More advanced diffusion models, such...
