A comparison of methods for the registration of tractographic fibre images. In: 22nd Annual Symposium of the Pattern Recognition Association of South Africa (PRASA), Emerald Casino and Resort, Vanderbijlpark, South Africa, 22-25 November 2011http://www.researchgate.net/publication/237007529_A_comparison_of_methods_for_the_registration_of_tractographic_fibre_imageshttp://hdl.handle.net/10204/763822nd Annual Symposium of the Pattern Recognition Association of South Africa (PRASA), Emerald Casino and Resort, Vanderbijlpark, South Africa, 22-25 November 2011Diffusion tensor imaging (DTI) and tractography have opened up new avenues in neuroscience. As most applications require precise spatial localization of the fibre images, image registration is an important area of research. Registration is usually performed prior to tractography. However more reliable images could be produced if a viable registration can be performed post tractography. This study shows two available techniques for direct registration of fibre images and explores novel adaptations of these. The methods register volume images derived from the fibres, and reapply the transformation from these registrations to the fibre images. The first method is a local affine registration and the second is a global affine registration. The local affine method produced superior results.enDiffusion tensor imagingDTIImage registrationTractographyConference PresentationGolding, D., Tittgemeyer, M., Anwander, A., & Douglas, T. (2011).
