GeoSP: A parallel method for a cortical surface parcellation based on geodesic distance

1 code implementation26 Mar 2021 Narciso López-López, Andrea Vázquez, Cyril Poupon, Jean-François Mangin, Susana Ladra, Pamela Guevara

We present GeoSP, a parallel method that creates a parcellation of the cortical mesh based on a geodesic distance, in order to consider gyri and sulci topology.

Cortical surface parcellation based on intra-subject white matter fiber clustering

no code implementations16 Feb 2020 Narciso López-López, Andrea Vázquez, Cyril Poupon, Jean-François Mangin, Pamela Guevara

The output is the complete labeling of cortical mesh vertices, representing the different cortex sub-parcels, with strong connections to other sub-parcels.

Parallel optimization of fiber bundle segmentation for massive tractography datasets

no code implementations24 Dec 2019 Andrea Vázquez, Narciso López-López, Nicole Labra, Miguel Figueroa, Cyril Poupon, Jean-François Mangin, Cecilia Hernández, Pamela Guevara

We present an optimized algorithm that performs automatic classification of white matter fibers based on a multi-subject bundle atlas.

Robust imaging of hippocampal inner structure at 7T: in vivo acquisition protocol and methodological choices

no code implementations9 May 2016 Linda Marrakchi-Kacem, Alexandre Vignaud, Julien Sein, Johanne Germain, Thomas R Henry, Cyril Poupon, Lucie Hertz-Pannier, Stéphane Lehéricy, Olivier Colliot, Pierre-François Van de Moortele, Marie Chupin

Multi-slab registration yielded high quality datasets in 96 % of the subjects, thus compatible with further analyses of hippocampal inner structure. CONCLUSION:Multi-slab acquisition and registration setting is efficient for reducing acquisition time and consequently motion artifacts for ultra-high resolution imaging of the inner structure of the hippocampus.
