We constructed phantoms for the characterization of ultra-low field (~100 uT) MRI systems and measured them at 132 uT, 1.5 T, and 3 T. The phantoms permit characterization of resolution, PD accuracy, and T1 accuracy. The phantoms can serve as common references and guide ultra-low field scanner development.
