Larmor#

A Python library and viewer for diffusion MRI

Whole-brain tractography drawn as tubes, coloured by direction.

FOD glyphs on a coronal slice; round FODs hidden.

Asymmetric FOD glyphs.

FOD peaks as lines, their lengths set by amplitude.

DTI colours of the principal direction, modulated by FA.

FA over the T1-like image on a sagittal slice.

Streamlines over a slice of the T1-like image in the 3D view.

Drawn by BrainViewer from the ISMRM 2015 Tractography Challenge data, processed with Larmor.
