In this work, we proposed that retrospective motion
correction of diffusion-weighted images by using the
optimum order for measuring diffusion directions is
proposed. As for this method, retrospective motion
correction is performed by using intermediate
mean-diffusivity (MD) maps generated from respective
groups of six consecutive DW images. The proposed method
can reduce calculation error caused by subject motion in
diffusion MRI without the need for additional scan time.
