Alignment of Tractography Streamlines Using Deformation Transfer via Parallel Transport

We present a geometric framework for aligning white matter fiber tracts. By registering tracts between brains, one expects to see overlap of anatomical structures that often provide meaningful comparisons across subjects. However, the geometry is highly heterogeneous, and finding direct tract-correspondence multiple individuals remains challenging problem. novel deformation metric allows compare while simultaneously obtaining registration. To accomplish this, are represented by an intrinsic mean along with fields tangent vectors from mean. In this setting, can determine parallel transport then register corresponding vectors. results bundle alignment on population 43 healthy adult
