    "abstract": "The methodology for obtaining two- and three-dimensional magnetic resonance\nimages by using azimuthally symmetric dipolar magnetic fields from\nferromagnetic spheres is described. We utilize the symmetric property of a\ngeometric sphere in the presence of a large externally applied magnetic field\nto demonstrate that a complete two- or three-dimensional structured rendering\nof a sample can be obtained without the motion of the sample relative to the\nsphere. Sequential positioning of the integrated sample-sphere system in an\nexternal magnetic field at various angular orientations provides all the\nrequired imaging slices for successful computerized tomographic image\nreconstruction. The elimination of the requirement to scan the sample relative\nto the ferromagnetic tip in this imaging protocol is a potentially valuable\nsimplification compared to previous scanning probe magnetic resonance imaging\nproposals.",
