Bias of Least Squares Approaches for Diffusion Tensor Estimation from Array Coils in DT–MRI

Least Squares (LS) and its weighted version are standard techniques to estimate the Diffusion Tensor (DT) from Diffusion Weighted Images (DWI). They require to linearize the problem by computing the logarithm of the DWI. For the single-coil Rician noise model it has been shown that this model does n...
