This work demonstrates the feasibility of reconstructing multiple b-value diffusion-weighted images (DWI) from a single RESOLVE k-space, where each blind was acquired with a different b-value. This multi b-value reconstruction uses the growing Constrained Alternating Minimization for Parameter mapping (g-CAMP) reconstruction method previously presented in ISMRM 2021. This can allow undersampling in the diffusion weighting dimension that is compatible with common undersampling schemes such as GRAPPA and multi-band EPI.
