Local
fiber tracking approaches are based on the 'walker' principle, the fibres are
reconstructed path-by-path by small successive steps along the tracts. On the
other hand global ideas try to reconstruct all fibres at once by optimizing a
certain global objective. Local algorithms are fast but suffer from
accumulated errors. Global methods have a more sound foundation but are very
complex to optimize. This abstract presents an approach, which fuses both
ideas while keeping their advantages. The experiments show that the approach
is orders of magnitude faster than recent global approaches while improving
the detection performance.
