Fiber tractography
WebThe general strategy of quantitative DTI fiber tracking is to create a 3D region of interest based on the voxels through which the fiber tracks pass. Quantitative DTI fiber tracking … WebScaling up tractography to meet these high-throughput demands yields new fiber tracking challenges, such as minimizing spurious connections and controlling for gyral biases. The aim of this study is to determine which of the two broadest classes of tractography algorithms-deterministic or probabilistic-is most suited to mapping connectomes.
