Hi,
I am looking for an appropriate reference for Eddy Current Correction (not the Beta version) and the algorithms used for the diffusion tensor estimation
Emma Robinson suggested to “simply refer to early eddy current correction papers such as J-F Mangin's MICCAI paper”.
My questions are:
- Mangin JF et al., Distortion Correction and Robust Tensor Estimation for MR Diffusion Imaging, Med Image Anal 6, 191-198 (2002): is this paper the correct one ? (= MICCAI paper (2001) 186-194)
- Does it mean that FSL uses for eddy current correction a slice by slice correction (not a whole brain global affine approach)?
- Mangin’s paper describes the Geman-McLure M-estimator algorithm for the diffusion tensor estimation. Does FSL use this algorithm?
- Or concerning the algorithms used to estimate the diffusion tensor (ordinary least squares or weighted least squares), we should cite this one: Basser et al, Biophysical Journal 66, 259-267 (1994)
Thank you
Oliver
