Announcing the IXI Aging DTI Template V2.0 Posted By: Gary Hui Zhang - Jul 26, 2010Tool/Resource: DTI-TK I'm pleased to announce the immediate availability of the IXI Aging DTI Template, release 2.0, for download. This new release substantially enhances the original template to provide out-of-the-box support for applying tract-specific analysis [1,2] to both healthy aging and dementia studies. The template is constructed from 51 normal elderly subjects (65-83 years old, 21 males and 30 females) drawn from the IXI brain database developed jointly by Imperial College of Science Technology & Medicine and University College London. It has been optimized for use with DTI-TK's registration and spatial normalization pipeline, as well as now the tract-specific analysis [1,2]. Further detail can be found in the manuscript [3] included as part of the template distribution available here: http://www.nitrc.org/frs/download.php/23...
