Making MR more accessible through precision quantitative MRI at 0.55T with optimized 3D MRF
Motivation: To enable high-resolution quantitaive imaging in economy-friendly 0.55T scanners. Goal(s): MRF with 1.2-mm isotropic resolution implemented on a FreeMax 0.55T scanner. Approach: MRF, subspace reconstructio, locally-low rank constraints, CRLB-optimized FA pattern, attention-based deep learning network for denoisig, trajectory correction, motion correction. Results: The proposed method was validated on phantom, in-vivo human brain and knee. Impact: Our research highlights the potential of affordable MRI scanners to deliver high-quality imaging.
