The present work reports on the development of fast 3D imaging at very-low magnetic field (6.5 mT) based on the intrinsic 1H NMR signal using balanced steady state free precession (b-SSFP). This result is the first implementation of b-SSFP at very low magnetic field. The presented optimized bi-planar electromagnet combined with fast 3D imaging strategies and sparse sampling has potential to reach clinical standards for patient imaging and open new perspectives for new generation of lower-cost high-performance purpose-built imagers practical for operation in hospitals, battlefield medical facilities, or forward triage.
