Abstract :
We have been constructing a statistical atlas of white matter fiber tracts, in which probability density maps of tract structures are stored with diffusion tensor parameters on spatially normalized brain data. The atlas is based on our fiber tract modeling method by using vector/tensor field reconstruction avoiding fiber-crossings. In this abstract, we describe the model-based DTT method by using our statistical atlas, and the preliminary results
