Validating validators : an analysis of DWMRI hardware and software phantoms

Diffusion Tensor Imaging (DTI) and its successor High Angular Resolution Diffusion Imaging (HARDI) are emerging MRI techniques for depicting in-vivo brain white matter, anatomy and connectivity. There is a wide range of utilizations of DTI and HARDI: from characterizing the local structure of the tissue, fiber tracking, segmentation, etc. However to apply any of the above-mentioned methods in a clinical setting, thorough validation is needed. The goal of the present work is to validate DTI and HARDI software phantoms, in regions of single and crossing fiber bundles, in relation to measured phantom data and in vivo data from human brain.
