| SFB603 - TP C9: Reconstruction and Visualization of Neural Pathways Neural pathways are structures within the human brain that are
important for sensory, motor and other integrative functions. To avoid
neurological deficits after brain surgery in brain tumor cases these
fiber tracts must remain intact. Contrary to nerves of the peripheral
nervous system which are coated with collateral tissue the neural
pathways within the brain are hardly distinguishable from the gray
matter. The differentiation of neural pathways is therefore only
possible by using the capabilities of diffusion tensor MRI which
measures the diffusion behavior of water molecules withing tissue. The
aim of the project is to develop new approaches for the exact
reconstruction of fiber tracts from diffusion tensor data which
requires an exact analysis of the tensor data as well as filtering and
registration techniques. In the future, the planning of surgery will
be improved and the inherent risk will be reduced. | Project manager:
