Most
common methods of fiber tracking rely on a knowledge based selection of ROIs
on appropriate slice and then generating the fibers from there followed by
cleaning and augmenting the bundle obtained. For a part of source and
destination ROIs the procedure is similar. However, in practice the selection
of the right ROIs and the subsequent additions and deletions are normally
quite time consuming in practice and involves a considerable amount of trial
and error. In this presentation we propose a principal eigenvector (e1) field
segmentation using which the selection of ROIs becomes less time consuming.
