Abstract:
1. A portable, wearable apparatus for obtaining signals from a specimen, comprising: one or more magnetic field generators that apply an uniform polarizing magnetic field to polarize nuclear spins in a target anatomical region of the specimen such that a magnetic flux density of the applied magnetic field are uniform throughout the target anatomical region, wherein the one or more magnetic field generators are associated with an article of apparel such that they are portable together; an array of optical atomic magnetometers arranged on the article of apparel, wherein the array of optical atomic magnetometers comprises vector-mode atomic magnetometers, wherein each of the array of optical magnetometers comprises a container having a chamber filled with an atomic vapor, whereby the array of optical atomic magnetometers on the article of apparel detects magnetic field vector signals from a relaxation of polarized nuclear spins in the specimen when the applied magnetic field is removed; and one or more microprocessors for recording or processing the magnetic field vector signals to generate an anatomical map of the target anatomical region from the detected magnetic field vector signals.
