The most common task in Diffusion MRI registration is aligning an anatomical reference with the tensor data or fiber-tracts derived from DTI. Because the DTI is tensor data, applying a spatial transform to this image is not trivial. Hence a common approach is to align the anatomical reference (such as a T1 MRI) to the DTI image and thus avoid having to resample the tensor. This, however, preserves the strong distortions often present in the DTI image and makes anatomical referencing difficult.

Case Inventory DTI

The most common task in Diffusion MRI registration is aligning an anatomical reference with the tensor data or fiber-tracts derived from DTI. Because the DTI is tensor data, applying a spatial transform to this image is not trivial. Hence a common approach is to align the anatomical reference (such as a T1 MRI) to the DTI image and thus avoid having to resample the tensor. This, however, preserves the strong distortions often present in the DTI image and makes anatomical referencing difficult.
