Principle Diffusion Direction Imaging Method Explained

Credit: Amanda Hammond, Human Connectome Project

Principal Diffusion Direction uses colors to map out the different directions that water molecules diffuse through the brain's white matter. This data is then used to reconstruct 3d representations of white matter tracts.

The colors are used to represent the spatial orientation of the fiber pathways: red is left-to-right in the brain, green is anterior-to-posterior, and blue is inferior-to-superior, in other words, RGB translated to XYZ.
