The localization of brain functional activity with respect to brain anatomy requires registration between a functional image and a reference high-resolution anatomical image. The fast functional magnetic resonance brain images acquired via echo planar imaging (EPI) in functional magnetic resonance imaging (fMRI) suffer from local geometric distortions. After performing standard rigid or affine registration,...
There exists a need for more accurate functional localization through the registration of functional to anatomical magnetic resonance brain images. This paper introduces a new software tool, named NPTK, that has been developed at the Signal and Image Processing Laboratory of the University of Texas at Dallas for improved functional localization in single- subject analysis. This software toolkit is...
