Analysis Tool For Diusion

Diusion Tensor Imaging (DTI) is becoming a routine mag- netic resonance technique to study white matter properties and alter- ations of fiber integrity due to pathology. The advanced MRI technique needs postprocessing by adequate image analysis and visualization tools. Whereas such tools have been developed at various research centers to drive methodological and clinical research, they have not become widely available as software freely distributed to the community. We have devel- oped an integrated software package for ecient processing, fiber track- ing, and interactive visualization of DTI data. This allows even non- experts to explore DTI data and to obtain results that so far were ex- clusive to reseach teams with strong computer science support. This report describes our eort to combine common, well-established process- ing methods for DTI data, a recently developed powerful fiber tracking method and a modern image analysis and visualization environment into an integrated tool.
