(A) Without implementing the data sharing, the subspace reconstruction only utilizes the data acquired for one diffusion direction (600 TRs by 8 acquisition groups). DP stands for diffusion preparation module and INV for inversion preparation module.
(B) Data sharing scheme. For the 1st diffusion-direction recon, 1–100 TRs of the 1–8 groups (red box) are used together with 101–600 TRs of all 48 groups (all diffusion directions, green box).
