Abstract

Claims (22)

1 . A device for sensing a magnetic field associated with an individual, comprising:

a. an array of magnetometers configured to sense the magnetic field associated with the individual; and

b. a shield configured to shield at least the array of magnetometers from an ambient magnetic field, wherein the shield is sized to at least partially enclose at least a portion of a body of the individual, wherein the shield comprises an open end and a closed end, wherein the open end is configured to receive the portion of the body of the individual, and wherein the closed end comprises a tapered shape, a conical shape, or a substantially conical shape.

2 . The device of claim 1 , wherein the shield comprises a plurality of layers, a permalloy, or a mumetal.

3 . The device of claim 1 , wherein the shield comprises one or more layers of coils.

4 . The device of claim 3 , wherein a coil is positioned within a portion of the shield where a measurement occurs.

5 . The device of claim 3 , wherein a position of a coil is determined according to a type of measurement.

6 . The device of claim 3 , wherein a position of a coil is adjustable for each measurement.

7 . The device of claim 6 , wherein the coil provides feedback to a controller that a desired positioned is achieved by the coil when adjusting the coil.

8 . The device of claim 7 , wherein the feedback from the coil occurs prior to a measurement, during a measurement, or after a measurement.

9 . The device of claim 3 , wherein a coil is an individual wire with gold plated contact.

10 . The device of claim 3 , wherein the one or more layers of coils comprise an inner coil layer and one or more outer coil layers.

11 . The device of claim 10 , wherein coils in the inner coil layer are distributed at a predefined angle to form a predefined number of coils.

12 . The device of claim 10 , wherein coils in the inner layer form at least a 6 fold symmetry.

13 . The device of claim 10 , wherein the inner coil layer is electrically isolated.

14 . The device of claim 1 , wherein a connection to an amplifier or transformer is opened during a measurement.

15 . The device of claim 1 , wherein the shield is 3D printed.

16 . The device of claim 1 , wherein the shield comprises a material formed in a hydrogen furnace.

17 . The device of claim 1 , wherein the array of magnetometers comprise a plurality of magnetometers arranged to match a generalized contour of the at least the portion of the body of the individual.

18 . The device of claim 1 , wherein the array of magnetometers comprise at least one of an optically pumped magnetometer (OPM), an optically pumped vector magnetometer, a zero field magnetometer, a superconducting quantum interference device (SQUID), an inductive pickup coil, a vibrating sample magnetometer (VSM), a pulsed field extraction magnetometer, a torque magnetometer, a Faraday force magnetometer, an optical magnetometer, and a combination thereof.

19 . The device of claim 1 , wherein the array of magnetometers are configured to be adjustable in a spatial positioning of the magnetometers or a number of the magnetometers, thereby accommodating a plurality of different configurations of the array of magnetometers.

20 . The device of claim 1 , wherein the tapered shape, the conical shape, or the substantially conical shape of the closed end is configured to reduce noise of the magnetic field sensed by the array of magnetometers.
