Welcome to the Tractometer website!
The Tractometer is a tractography evaluation tool. It is used to evaluate the end effects on fiber tracts of different :
- acquisition parameters & artefacts (b-value, number of directions, denoising or not, averaging or not)
- local estimation & modeling techniques (tensor, q-ball, spherical deconvolution, spherical wavelets, compartment models)
- tractography parameters (masking, seeding, stopping criteria)
- tractography algorithms (deterministic, probabilistic, geodesics, global).
NEWS
- 2017-05-15: The scoring system used in the Challenge is now available. See the tools page.
History
The first set of experiments used to produce results for the Tractometer (presented at MICCAI 2012) were based on a revisited
FiberCup analysis.
The Tractometer was also used to generate results and evaluate the submissions to the
2013 ISBI Hardi reconstruction challenge.
More recently, the Tractometer was used to score the
ISMRM 2015 tractography challenge.
Very interesting results
were presented in the talk that was given during the Diffusion Study Group
session at ISMRM 2015. The slides are available here.
The current goal for the Tractometer is to make it easier for people to submit new phantoms, datasets, tractograms and
tractography methods so that better insights can be gained on the current trends.
The Tractometer can highlight limits of the
algorithms and contribute to elucidating the open questions
in diffusion MRI fiber tracking
processing pipelines : from raw data to
connectivity analysis.
