Abstract
Devices disclosed according to various embodiments use one or more arrays of atomic magnetometers to directly detection of relaxation of magnetic field induced subatomic precession within a target specimen. The disclosed devices and methods relate to application of utilization of a magnetic sensor with unique properties requiring changes in design, allowing new functions, and requiring alternative analysis methodologies. Various embodiments are also directed to methods for obtaining and processing magnetic signals. These methods may take advantage of the unique spatial arrangement of the atomic magnetometers and the capacity sensors to be used in either a scalar or a vector mode. Various embodiments have advantages over current techniques utilized for imaging of anatomical and non-anatomical structures. Such advantages may include, for example: development of a wearable, portable array, lower power consumption, potential wafer-level fabrication, the potential for development of a more rapid signal, decreased need for development of strong magnetic fields, and lower cost allowing wider availability.
