1. A nuclear magnetic resonance (NMR) system, comprising:
a set of magnets producing a magnetic field over a region of interest within a bore configured to receive a finger of a user, wherein the set of magnets comprises an array of magnets arranged around the bore;
a transmitter;
a receiver comprising a surface coil, wherein a central axis of the surface coil intersects with a pulp of the finger, wherein a width of the bore along a first axis is greater than a height of the bore along a second axis, the second axis perpendicular to the first axis, wherein the first axis is parallel to the central axis of the surface coil, wherein the second axis is perpendicular to a longitudinal axis of the bore; and
a processing system configured to:
using the transmitter, transmit an electromagnetic pulse sequence;
using the receiver, sample a receive signal; and
determine a blood analyte concentration in the finger based on the receive signal.
