Abstract
A portable magnetic resonance imager has a probe. One or more magnets are disposed in the probe, creating at least one magnetic field to precess protons at a target. A magnetometer disposed in the probe has a light source and a nitrogen vacancy diamond. The light source projects a light on the nitrogen vacancy diamond. The nitrogen vacancy diamond fluoresces in response to the light. A photodetector detects the fluorescence and produces a signal in response thereto indicative of the decaying of precessing protons having precessed in the presence of the one or more magnets.

A portable magnetic resonance imager comprising:
- a probe;
- two or more magnets, disposed in the probe, creating at least one magnetic field to precess protons at a target;
- a magnetometer disposed in the probe, the magnetometer having a light source, a nitrogen vacancy diamond, the light source projecting a light on the nitrogen vacancy diamond, the nitrogen vacancy diamond fluorescing in response to the light;
- and
- a photodetector detecting the fluorescence and producing a signal in response thereto indicative of the decaying of precessing protons having precessed in the presence of the two or more magnets.
