文摘
- •
We present a new method for correction of eddy current-induced distortions and subject movement in diffusion data.
- •
It is based on alignment to predictions based on a Gaussian process
- •
The results indicate that one can achieve reliable corrections even for high b-value data (b = 7000).
- •
A comparison to correlation ratio based registration (eddy_correct) indicates that the new method is vastly superior.
