    "abstract": "We introduce the concept of computerized tomographic microscopy in magnetic\nresonance imaging using the magnetic fields and field gradients from a\nferromagnetic probe. We investigate a configuration where a two-dimensional\nsample is under the influence of a large static polarizing field, a small\nperpendicular radio-frequency field, and a magnetic field from a ferromagnetic\nsphere. We demonstrate that, despite the non-uniform and non-linear nature of\nthe fields from a microscopic magnetic sphere, the concepts of computerized\ntomography can be applied to obtain proper image reconstruction from the\noriginal spectral data by sequentially varying the relative sample-sphere\nangular orientation. The analysis shows that the recent proposal for atomic\nresolution magnetic resonance imaging of discrete periodic crystal lattice\nplanes using ferromagnetic probes can also be extended to two-dimensional\nimaging of non-crystalline samples with resolution ranging from micrometer to\nAngstrom scales.",
