Differential geometric characterization of white matter fibre tracts
Diffusion MRI is a non-invasive imaging method which exploits the property that fibrous structures restrict the random motion of water molecules to provide maps of biological tissues. Indeed, water molecules undergo random motion associated to thermal fluctuations. Yet, they can encounter obstacles, interact with many tissue components such as cell membranes or fibres. Hence, the observation of the motion of water molecules provides us information on the geometric organization of cells in tissues.
Considering the brain, diffusion anisotropy of water molecules can be observed in white matter: as opposed to grey matter, which essentially consists of nerve cell bodies and glials cells, white matter is composed of axonal fibres organized in bundles. There the diffusion of water molecules is faster in the direction of the fibres than in the perpendicular way. This feature can be exploited to map out the brain connectivity.
Besides, diffusion MRI has macroscopic (millimetre) resolution whereas axons are microscopic in diameter (about 0.001 mm across). Then one single voxel of the 3D image may contain several fibre bundles. The aim of my project is, by analysing MRI data, to make inference on the microstructure of the brain and to estimate multiple-fibre directions within a single image voxel. I use a differential geometric model developed by Peter Savadjiev : the curvature class.
