Diffusion-tensor image registration

Abstract

In this chapter, we introduce the problem of registering diffusion tensor magnetic resonance (DT-MR) images. The registration task for these images is made challenging by the orientational information they contain, which is affected by the registration transformation. This information about orientation and other aspects of the diffusion tensor are exploited in the development of similarity measures with which to guide DT-MR image registration, and the current state-of-the-art is reviewed. The chapter concludes with a discussion of some outstanding issues and future avenues for research in diffusion tensor registration.
