DOI: 10.1002/mrm.27471
Abstract: Human connectomics necessitates high‐throughput, whole‐brain reconstruction of multiple white matter fiber bundles. Scaling up tractography to meet these high‐throughput demands yields new fiber tracking challenges, such as minimizing spurious connections and controlling for gyral biases.… read more here.
