In this work, we propose a unified compressed sensing framework to reconstruct the diffusion signals and propagators from raw data sub-sampled from both q-space and k-space. With the proposed method, we can reduce scanning time in both k-space and q-space, and obtain good reconstruction quality with low RMSE compared to the estimation using fully sampled data.
