The unknown contrast sources are iteratively reconstructed through a Bayesian compressive sensing (BCS) technique. The proposed MR-BCS-CSI approach is evaluated using synthetic data, demonstrating its accuracy and robustness. Comparative analyses with recent state-of-the-art methods further underscore the effectiveness and competitiveness of the approach.
