An axial plane based high order eddy current correction (HOEC) method was previously proposed to mitigate diffusion gradient direction dependent image distortion often seen in images acquired with the Stejkal-Tanner diffusion sequence, which is known to produce images with higher signal-to-noise ratio than the corresponding dual spin echo images due to generally shorter echo time. In this paper, we show that HOEC correction can be extended to arbitrary scan plane with arbitrary diffusion direction through the application of gradient and polynomial basis rotation matrices.
