DETERMINATION OF AN EMPIRICAL STATISTICAL DISTRIBUTION OF THE DIFFUSION TENSOR IN MRI

摘要

Diffusion tensor magnetic resonance signals are analyzed. Diffusion weighted signals are acquired, each signal having a plurality of voxels (10). The diffusion weighted signals are sampled to obtain at least one set of resampl ed diffusion weighted signals (11). A diffusion tensor for each voxel is determined from each set of the resampled diffusion weighted signals (12). A n empirical statistical distribution is determined for a quantity associated with the diffusion tensor from the diffusion tensors determined from the at least one set of the resampled diffusion weighted signals (13).
