Abstract

In this paper, we describe work on the non-rigid registration of diffusion tensor magnetic resonance (DT-MR) images. The registration task for DT-MR images is complicated by the fact that DTs contain orientational information, which is affected by the registration transformation. We discuss how to properly account for this effect in the implementation of a registration algorithm which fully exploits this important aspect of the DT to improve the anatomic accuracy of the registrations.
