Abstract
The nuclear magnetic resonance system can include: a set of magnets, a housing, a set of coils (e.g., receive coil, transmit coil, gradient coil, active shim coil, etc.), and a processing system. The nuclear magnetic resonance method can include: applying a pulse sequence, acquiring a signal, and processing the signal (e.g., to determine blood analyte levels).
Claims20
A nuclear magnetic resonance (NMR) method, comprising:
- transmitting a sequence of electromagnetic pulses using a transmit coil, the sequence of electromagnetic pulses comprising:
- an excitation pulse configured to excite a finger of a user;
- a first set of refocusing pulses;
- and
- a second set of refocusing pulses;
- transmitting a sequence of gradient pulses using a set of gradient coils, wherein each gradient pulse in the sequence of gradient pulses is transmitted approximately concurrently with a refocusing pulse in the second set of refocusing pulses, wherein the sequence of gradient pulses is configured to select a target region of the finger;
- sampling a receive signal using a surface coil;
- and
- determining a blood analyte concentration in the target region of the finger based on the receive signal.

A nuclear magnetic resonance (NMR) system, comprising:
- a set of permanent magnets producing a magnetic field in a finger of a user;
- a set of coils comprising a transmit coil, a set of gradient coils, and a surface coil;
- and
- a processing system in communication with the set of coils, wherein the processing system is configured to:
- using the transmit coil, transmit a sequence of electromagnetic pulses comprising:
- an excitation pulse configured to excite the finger and a set of refocusing pulses;
- using the set of gradient coils, transmit a sequence of gradient pulses concurrent with a subset of the set of refocusing pulses, wherein the sequence gradient pulses are configured to select a target region of a pulp of the finger;
- using the surface coil, sample a receive signal;
- and
- determine a blood analyte concentration in the target region of the finger based on the receive signal.
