Abstract

A phantom for multinuclear simultaneous integrated magnetic resonance imaging includes a plurality of sealed containers, where a partition I and a partition II are provided in the sealed container and intersect with each other; the partition I and the partition II divide the sealed container into a plurality of subspaces that are interconnected; a thickness of the partition I is equal to a resolution of a nuclide 1H, and a thickness of the partition II is γH/γX times of the resolution of the nuclide 1H, where γH is a gyromagnetic ratio of the nuclide 1H, and γX is a gyromagnetic ratio of a pre-imaging nuclide X; the sealed container is filled with a mixture; and the mixture includes all pre-imaging nuclides. In the phantom, the partition I and the partition II are designed according to a ratio of gyromagnetic ratios of nuclides, and are combined with a mixture including all pre-imaging nuclides.
