In this work, we accelerate the high-SNR, high-spatial resolution in vivo diffusion MRI technique gSlider by applying subsampling jointly in the k,-q, and RF-encoding space. Good reconstruction quality is achieved if complementary information from the multi-dimensional space k-,q-, and RF-space is combined in a complementary fashion and the reconstruction problem is solved jointly.
