A new
model-based approach using low-rank and sparsity constraints is presented for
reconstructing the accelerated magnetic resonance fingerprinting (MRF)
time-series images. By enabling high-quality reconstructions of
contrast-weighted images from highly-undersampled data, the proposed method produces more accurate estimates
of tissue parameter maps compared to the conventional gridding based reconstruction
of the time-series. Ultimately, the goal is to reduce imaging time for MRF
acquisitions and improve spatial resolution.
