Reconstruction of neuronal pathways from diffusion imaging data

Diffusion imaging provides information about the course and location of white matter tracts. White matter tracts, i.e. motor or sensory pathways, are important structures within the human brain. For neurosurgery, diffusion imaging data is of high value since these fiber tracts must remain intact in order to avoid neurological deficits after brain surgery.

However, the reconstruction of neuronal structures from diffusion imaging data is a non-trivial task due to the complexity of the diffusion information that is captured per voxel. Our research in this field addresses the reconstruction of the diffusion signal based on compressed sensing, as well as tracking and clustering of white matter pathways.
