Abstract
A method of imaging a sample. A magnetic particle is positioned near a sample to be imaged. A strong direct current (DC) magnetic field is applied in a non-perpendicular direction relative to the sample, and a relatively weaker radio frequency (RF) magnetic field is applied. A plurality of polarized magnetic spins of the sample is produced in a region near the magnetic particle, and resonance of the plurality of magnetic spins is detected. The detected plurality of magnetic spins can be used to provide an image of the sample.
