متن کاملHow many diffusion gradient directions are required for HARDI?
Introduction: While the minimum number of directions required for robust diffusion tensor imaging (DTI) has been extensively studied [1-4], the equivalent studies have not been performed for high angular resolution diffusion-weighted imaging (HARDI) methods. This is due in part to the fact that many HARDI methods are available, each with their own requirements and parameters, making it difficul...
